English Is Plain Weird
"English is not normal the more you hang around and linguistics to more languages you mess around with the more language histories you learn the more you realize that this language that i'm speaking right now. Although it has many advantages for muendane and often unfair reasons this language is not normal and by that. I don't mean that it's extraordinary. I mean that english is weird as languages go and i actually find this one of the funnest things that i know about language and yet it's very hard to perceive it because it's the language that we speak and it's the language spoken by so very many other people in the world. English can feel so normal. But it's actually a highly abnormal thing. And i want to share with you. How it's abnormal and what i mean specifically is that when we think about language we have to think about the history of homo sapiens and the history of homo sapiens. As far as is known now goes back about three hundred thousand years and we might suppose that language emerged then. It's the way. I tend to think of it now. It's also possible. That homo erectus had language in which case language goes back about one point eight million years that is daniel ever another linguist view and i am pretty convinced of it but let's be conservative for now. Let's say that it's three hundred thousand years. The thing is for most of that time. Humanity was different from what most of humanity is now. The neolithic revolution that large scale architecture and the development of what we call civilizations. That's only ten thousand years ago or so and so what that means is that i say two hundred ninety thousand years what humanity was relatively small groups living on the land language developed there. So anything that happens to language after that is a departure from what language normally was what this evolved to be
"To understand millan kovic cycles. We have to understand each of the cycles which the earth goes through individually. There are several of them. And it's gonna take a bit of visualization to get the concept via podcast where there are no visual aids. But it shouldn't be too difficult. We'll start by going through the cycles that the earth itself goes through to understand these need to think of the earth as a spinning top when the top spins. it's usually not perfectly upright. The top will be tilted somewhat just like atop. The earth has a tilt to rotation currently the earth tilts twenty three point five degrees. And that is what is responsible for the seasons. However that tilt known as obligatory isn't static it actually wobbles back and forth between twenty two point one degrees and twenty four point five degrees right now. We're in the middle of such a cycle. The time it takes to complete one full cycle of going from twenty two point one degrees to twenty four point five degrees and back again is forty one thousand years the greater the tilt the more sun the polar regions will get in the summer and the more extreme the seasons are the next part of the cycle is axial procession if you can imagine the spinning top again as it. Spinning the axis of the top is rotating. Circle isn't just tilting. In one direction on the earth the direction of our access in the north currently points to the north star players this temporary over the course of twenty five thousand seven hundred and seventy one point five years. The earth's axis will go in a circle that means that not only will the north star. Not be the northstar at some point but twenty five thousand seven hundred and seventy one years from now it will be the northstar again while the earth is going about it cycles on it's wobbling and spinning access there are also things happening to the earth orbit itself for this part instead of a spinning top. I want you to visualize a spinning plate. The edge of the spinning plate would be the orbiting. The earth and at the center of the plate would be the sun the first orbital cycle is the orbital eccentricity cycle the orbit of the earth around. The sun isn't a perfect circle. it's slightly elliptical the shape of that ellipse changes over time. And how much it deviates from a circle is known as eccentricity the eccentricity cycles between point zero zero three four which is almost perfectly circular two point zero five eight which is more slightly elliptical the changes due to the gravitational pull of large planets like jupiter and saturn. This cycle takes about one hundred thousand years. The next cycle is called app sill procession. If you can imagine that played again this time imagine it. As more of an oval plate as the earth is going around its orbit around the edge. The plate itself is rotating that means be closest and farthest point that the earth is from the sun will change over time. This cycle is about one hundred and twelve thousand years. Finally there's a cycle for orbital inclination. That rotating plate isn't flat and actually tilts and the tilt changes over time as well. This cycle is about one hundred thousand years as well and is very close to the same length. As orbital eccentricity cycle each of these cycles involves relatively small changes over long periods of time however they can compound each other or they can mitigate each other all of these cycles have been known for a while somewhere known back as far as antiquity and others were more recently discovered in the nineteenth and twentieth centuries in one thousand nine hundred eighty s serbian astrophysicists named bulletin. Millan kovic put all the pieces together. He realized that these cycles closely followed the patterns of ice ages in particular three of these axial tilt eccentricity and procession all affected the amount of sunlight that would fall on the northern hemisphere. These cycles could either cancel each other out to moderate the strength of seasons or they could compound each other making the seasons even more powerful in particular. What really mattered was the amount of sunlight falling on the northern hemisphere. In the summer why the northern hemisphere that is where most of the land is sixty eight percent of the land on earth is in the northern hemisphere land. Can't store heat as well as water. Which means that ice can form on it. Easier ice reflects sunlight which can cause further cooling during an ice age most. The ice accumulates in the northern hemisphere in the south is can only accumulate to a point before it hits warmer water and the ice will cleave off to form icebergs. Glaciers depend on how much of the ice melts during the summer when the earth is at its maximum tilt more sun is hitting the northern hemisphere in the summers if the orbit of the earth is such that it's at its closest point to the sun. When this happens summers will be very intense and ice will melt when he opposite happens when the tilt is at a minimum and the earth is farther away in the summers ice will not melt as much and glaciers will grow. All of these factors individually are rather small at its closest point to the sun which currently happens on january fourth. Remember back to my episode on why we celebrate new year's day when we do there's only about six percent more solar radiation hitting the earth than when we are at the farthest point likewise the axial tilt of the earth only changes a few degrees however these effects can be big enough when they work in conjunction to cause an ice age. The observed strength of ice ages is usually found to be stronger than the millen kovic cycles would suggest leading some climatologists to think that there might be a positive feedback mechanism at work. Something which causes the planet to cool faster than expected. The timing of ice ages is still being worked on. Kovic predicted that i would be about forty one thousand years apart and that was true up until about one million years ago since then ice ages have come at about one hundred thousand years which corresponds to the eccentricity cycle. Milne kovic cycles aren't just unique to earth like the earth. Mars has all the cycles. I just mentioned except that the timing and the extent of the cycles are different. Researchers estimate that mars has had between six and twenty ice ages over the last eight hundred million years. The martian milankovitch cycle might bring about an ice age every four hundred thousand to two point one million years. Some of you might be wondering if mellon kovic cycles are responsible for the recent climatic changes measured over the last several decades and the answer is no milakovic's cycles take thousands. If not tens of thousands of years to change their effects. Camping noticed over periods short as a decade so the next time you think about the earth as a spinning ball in space realize that the spinning the orbit isn't a static unchanging thing it's always slowly changing and there are cycles within cycles within cycles
Scientists Have Found Some Truly Ancient Ice, But Now They Want Ice That's Even Older
"It's chilly across the country today. Highs of just fifty eight in miami and sixteen in minneapolis which makes minnesota colder than an arctic as mcmurdo station but the cold weather doesn't last forever in the twin cities and in antarctica. It does ice their last hundreds of thousands even millions of years and as npr's nell greenfieldboyce reports that makes an arctic the perfect place to find some of the oldest ice in the world. Just how old is the oldest ice. On earth john higgins says. Nobody really knows you know. Would i be surprised at this point. We had five million-year-old is i mean. I'd be surprised. But not it's not unfathomable i think he and some colleagues recently collected ice samples in antarctica. That were later analyzed and shown to be as old as two point six million years. It's beautiful stuff when you pull out. The is it. Essentially as crystal clear accepted filled with tiny bubbles the bubbles contain air from when the ice formed and this trapped air is what scientists are really after higgins says if you want to understand how gases like carbon dioxide have affected the climate throughout history. You know you can't really do better other than getting a time machine and going back in time and taking an air sample then using these ice cores which physically just trap samples of ancient air to release that ancient air. All you have to do is melt the ice. That's the sound of a research camp manager in antarctica making drinking water by melting scraps of two hundred thousand year old ice in a metal pot to actually collect an analyze the release gases however ancient is has to melt in a lab. Sarah shackleton studies old princeton where she gets to watch the trapped air bubble out and that is something that i don't know if i'll ever get sick of watching. It's actually like pretty mesmerizing and one thing. That's released surprising every time to muse. Just how much gas is actually in the ice. She says it's a lot and samples from time. Periods undergoing past climate changes could be used to help make predictions about the future. One of the biggest questions in terms of kind of the modern warming and look anthropogenic. Climate changes helmich warming. Do should we expect with the amount of co two that we have in the atmosphere now. Antarctica has been covered by an ice sheet for at least thirty million years. But it's actually pretty hard to find really old ice. John gooch is a geologist. At the university of minnesota he says while snowfalls constantly add new layers of ice to the top of the ice sheet the oldest layers at the bottom can disappear. That's because of geothermal heat coming up from the ground so the rocks are giving off heat of slowly over time and so that has the potential to melt ice at the bomb. Still bits of super old ice like that two point six million year old sample can sometimes be preserved at the ice sheets edges the older snippets of ice. That we've been able to find come from places where the ice has flowed up against a mountain range and been exposed at the surface in those spots though. The ice can be all jumbled up and messy. It's not nice layers that have been laid down sequentially over a long continuous stretch of earth's history to get a neatly layered ice sample like that. Scientists need to drill straight down through the thick icesheet so far the oldest ice collected that way goes back eight hundred thousand years. Gooch says the goal now is to drill down a couple of miles to reach ice. That's older a million to two million years old whether or not we'll be able to find it at the bottom of the ice sheet where we can recover a relatively simple continuous record. Is i guess. That's the sixty four thousand dollar question at team from china has drilling underway a group from europe. We'll start in november. What everyone wants is i-i samples that cover a key time period about a million years ago. When there was a dramatic shift in the planet cycle of ice ages. Those had been coming every forty thousand years or so but for some reason that pattern ended and it changed to every one hundred thousand years instead unto us working on climate. That's a really big deal. Eric wolf is a climatologist with the university of cambridge in the united kingdom. It's a really big question as to why that change is fundamental tower climates. Work in a way you could say. We don't really understand today's climate. If we don't understand why we live in one hundred thousand year will draw the forty thousand year world. The coronavirus pandemic basically ruins the arctic research season. That would've been happening now but starting next fall researchers will be backed down there searching for really old ice nell greenfieldboyce npr news.
The Denisovans Expand Their Range Into China
"Like modern humans than neanderthals roamed widely throughout europe. We know this because they left behind. Extensive evidence usually bones or tools but their cousins. The denisovans our more mysterious until recently they were conclusively linked only to a single cave in southern siberia called denisova cave which lies between kazakhstan and mongolia in that cave. Scientists had found a finger bone three teeth and piece of skull which tip them off to the existence of a whole new lineage of ancient human now scientists have uncovered more of the range for the denisovans says de endo mossy lonnie of the max planck institute in germany. His team turned up evidence. The ancient humans occupied a high mountain cave on the tibetan plateau. Called by shia cave belongs to monks and -mongst things that it's a very holy place in fact among found a piece of jawbone there in nineteen eighty which has been tenuously linked to the denisovans salani and his team have now unearthed more conclusive evidence by sifting through cave sediments and sequencing the genetic evidence. The denisovans left behind. Buddy decay of people chests. Gabbing down the side like bleeding. There are coping ping could left their dna. The dna appears in layers suggesting the denisovans inhabited the cave as far back as one hundred thousand years ago as well as at sixty thousand years ago and perhaps even as recently as forty five thousand years ago meaning. The denisovans might overlapped in this region with modern humans. The results appear in the journal. Science mossy lonnie says. This method could enable more denise in detective work to this like so many caves when we have evidence of human activity but we don't have opening remain so if he can exploit to sediment can actually start to track down in segment. The denisova dini denise evans live on today in the genomes of some modern day humans from the south pacific further. Genetic work like this might give scientists more clues where early homo sapiens. I met and mixed with the elusive denisovans.
What crows teach us about death with Kaeli Swift
"Whether we want to or not human spend a great deal of time considering death. And it's possible we've been doing. So since shortly after Homo Sapiens, I began roaming the landscape. After all the first intentional human burial is thought to have occurred around one hundred thousand years ago. What might those early people have been thinking? As they took the time to dig into the earth deposit, the body and carefully covered up again. Were they trying to protect it from scavengers or stymie spread of disease? Were they trying to honor the deceased or did they just not want to have to look at a dead body? Without the advent of a time machine. We may never know for sure what those early people were thanking. But one thing we do know is that humans are far from alone in our attention towards the dead. Like people some animals including the corvettes, the family of birds that houses the crows. Ravens Magpies Jays also seemed to pay special attention to their dead. In fact, the rituals of corvettes made acted as the inspiration for own. After all, it was the raven that God sent down to teach Kane how to bury his slain brother able. But despite the clear recognition by early people that other animals attend to their dead, it's only fairly recently that science has really turned its attention towards this phenomenon. In fact, formal name for this field comparative Anthology. First introduced until twenty sixteen. In this growing field, we are beginning to appreciate what a rich place the natural world is with respect to how other animals interact with their dead, and it's in this growing body of knowledge at that time machine to our early ancestors might be possible. So what are we learning in this growing field? Well right now, we can split our understanding into two main groups. In the first, we have animals that display stereotyped predictable behaviors towards their dead and for whom much of what we understand about them comes from experimental studies. This group includes things like social insects, bees, ants, and termites, and for all of these animals colony hygiene is of critical importance and so as a result, these animals display rigorous undertaking behaviors in response to corpses. For example, they may physically remove carcasses from the colony they may consume them. They may even construct tombs. We see similar hygiene driven responses in some colony living mammals rats, for example, will reliably Berry cage mates that have been dead for forty eight hours. In our other group, we have animals that display more variable, perhaps more charismatic behaviors and for whom much of what we understand about them comes from anecdotes by scientists or other observers. This is the animals whose death behaviors I suspect might be more familiar to folks. It includes organisms like elephants which are well known for their attendance to their dead even in popular culture. In fact, they're even known to be attracted to the bones of their deceased. It also includes animals like primates which display a wide variety of behaviors around their dead from grooming them to. Prolonged attention towards them guarding them even the transportation of dead infants and that's actually behavior we've seen in the number of animals like the dolphins. For example, you may remember the story of Taleh, the ORCA in the resident J. pod in the puget sound who during the summer of two thousand eighteen carried her dead calf for an unprecedented seventeen days. Now a story like that is both heartbreaking and fascinating, but it offers far more questions than it does answers for example, why did Kerry her calf for such a long period of time. who she just that stricken with grief. Wishy more confused by her unresponsive infant. Or is this behavior just less rare in orcas than we currently understand it to be
Neanderthals Used Glue
"There was a time when neanderthal was used as an insult with the implication that this extinct species or perhaps sub species of hominids was unintelligent and unsophisticated. But the more research that goes into how neanderthals lived the more we learn that they were quite clever. For example, they made an used glue millennia before we humans figured it out. Pay. Bring stuff is Christian. Sager here. There are some things people just can't live without. So we invented them way before we ever invented writing coats, knives, roofs, fire turns out. Another thing are prehistoric precursors needed that we still need today is the ability to stick one thing to another thing, and then you know have them stay that way which is why neanderthals had glue they might have been caveman, but they weren't savages now. Hormone neanderthalensis used their glue a viscous tar distilled from Birchbark to fix weapons on the heads of a tool onto a half or maybe a handle and neanderthals were actually the leaders in glue technology beating US Homo Sapiens to the punch by more than a hundred thousand years they began brewing tar two, hundred thousand years ago whereas the earliest evidence of modern humans using tree resin as adhesive appears less than one hundred, thousand years ago. Research published in twenty eleven shows that neanderthals had the ability to create in control fire. So does the fact neanderthals could manipulate fire to produce tar proved they weren't as dimwitted as we'd like to assume scientists have been curious about the process neanderthals used to make their glue a new study published in the journal Nature Scientific reports suggest three different ways neanderthal tar could have been manufactured after all it had to be produced. This stuff wasn't just secreted from trees growing in the forest, but how difficult was making tar? Tar Making is definitely a process. No matter which way you go about the research team figured that out through a fancy bit of experimental archaeology, they devised three different potential methods of extracting sticky stuff from birchbark the ash mound method where tightly rolled layers of birchbark are covered in ash and embers the pit role cigar roll method where one end of Bertril is lit emplaced burning side down into a small collection pit and the raised structure method where a birch bark container was placed in a pit beneath an organic Mesh, which holds loosely rolled bark that is then covered with earth and fire. After recreating the three tar production methods, the scientists assess each according to three criteria the yield temperature in complexity the team found that though the simplest fastest method, the ash mound method yield digest a pea sized amount of tar the most complicated time consuming method that's the race structure method produced fifteen to twenty times more and was also the most efficient. They also observed that regulating the temperature of the fire didn't make much of a difference to the product even though they have no evidence that the neanderthal way. Of Making Tar. was similar to any of their experimental methods making the connection between the Birchbark the fire and the tar would have required that neanderthals possess a proclivity for abstract thought. So whether they were making easy inefficient tar instead of something like the high yield method requiring a folded cup and a little grill made of sticks neanderthals had something going for them. They were seriously using their
The earliest human footprints in Arabia
"Now, we have contributing correspondent and gibbons. She wrote this week about the likely earliest human footprints on the Arabian Peninsula high an hi Sarah how old or how early are these footprints but that's a good question. They threw a whole package of dating methods at them and came up with in the Ballpark of twenty, one, thousand, two, hundred, and ten, thousand years old. Now the dates are not absolute. There's some questions about them, but that's a pretty good ballpark. How does this age compare to previous hints or clues that humans modern humans early modern humans were on the Arabian Peninsula. Here's the. We know that early hominids members of human family have been migrating out of Africa for two million years because we find fossils of our ancestors in the public of Georgia we find them in. Asia. We find them in Eurasia place, but we don't know how they got out and the most logical route is they had to walk through Rabia because they couldn't fly. They couldn't paddleboats a at that point the one landmass in the way between Africa where humans arose originally, our ancestors arose and Eurasia is through Arabia. So we know they had to go through there, but there's a huge gap there are. No tools older than three hundred to five, hundred, thousand years, and what is there is not definitive. The only fossil have a member of the human family from Arabia is a finger bone that is about eighty eight, thousand years old. So the mystery is, where's the evidence of members of the human family marching through Arabia, and then the second part of that is modern humans specifically, our ancestors Homo sapiens arose probably in Africa, because we see fossils in the ballpark of one, hundred, eight, thousand, three, hundred, thousand years of Proto early Homo, sapiens arising and Africa, and then we find more of these sort. Of Early Homo Sapiens in Greece dating possibly back to as early as two hundred and ten thousand. So we know that they got out right now we're just trying to find evidence. Is there something that going on in the Arabian Peninsula that either people didn't want to hang out there for very long or that erased a lot of evidence. Reagan. Peninsula, has covered with desert's it's very dry today the food desert where they found these fossils is parched arid but there were periods in the past where the planet was cooler and wetter, and during those times hundred, twenty, five, thousand years ago it was. One of them, it was green radio was covered with tens of thousands of lakes. They were grasslands between them. If you think about these early human ancestors, it's not a separate continent or a separate place for them to go to its Afro Arabia, right? Yeah. So it's an extension of Africa if the client is good and they're following large game, how were they able to find these footprints? This is a very large area and it's a few remnants of human passing through. Yes. So this team will have by Michael, Leah and it's an international team of Saudi Arabians in a number of people on. Has Been doing a search of scouring the deserts of. Arabia. For the last decade, they start with satellite imagery which helps them see parched ancient lake beds which have sort of characteristic white halio souls often these ancient sediments that stand out in the satellites and then go down to ground truth what they see on the satellites, an airplane shots they go in on foot in jeeps, and in this case they saw this ancient. Lake better rolling out as white sediment. It had just been recently exposed by Rosen and they found the footprints of the animals which was amazing and as I looked closer to one hundreds of footprints, it was four hundred mostly animals but they did identify a small number. It was seven that seemed to be human footprints. So they knew right away they were very excited about that that this was something that was important how Can you tell that they're human footprints and not some other upright walking relative? There's not a whole science of studying human footprints ever since the first ones are found in la totally in Tanzania and Kenya there've been a number of footprints that have been studied people use three D morphometric dimensional analysis with computational imaging or can really look at the depth and they could model how much weight would have been needed to make. That footprint, the length of the foot, the stride between the steps, and then they've done studies living people in their footprints in Africa to sort of test out those ideas and Lo, and behold when they do that to these footprints, they seem to come up with somebody kind of humor that was taller and maybe a little lighter weight more like a modern human of Homo sapiens and say an Andrew Tall so based on that. They say, Oh, these probably were made by Homo sapiens although we cannot rule out that nanotubes might have been there to is there anything else can tell about these people by looking at these marks I think if they get more, they can start to tell about their social structure footprint studies in Africa. I've got quite complicated where you could see the direction that they're going in the payson different members of social groups you can. To see what they are the packs of humans look like you know, what size are they how many are in these groups? What are they doing a lot of the way in this case, they're not spending a lotta time. They're just sort of walking through. This is a bantering group. What is really really cool. Though is that footprint site these are a snapshot of a single moment in time a single day most of the. Time when you have an archaeological site in a layer soil that you get the fossils of the tools and the dates, all that took place. This fan is usually hundreds of thousands, tens of thousands of years. So if you find an animal bone near a prominent human early Human Boehner tool, you don't necessarily know fear there at the same time as parch with footprints like these these were lay down in the same day maybe. A couple of days and they dried out and then got caught up in preserved. So we know they were all there at the same time. So you get this really cool day in the life look at the and of the animals they were with, which is really cool in this case and lots of animals. Yes. Almost four hundred footprints of animals including very interesting. A wild asses which I don't think we're carrying burdens but. That's kind of neat and they were elephants and the thing that's interesting about the elephants as their popular disappeared for the Middle East, just in Africa. Thanks for three hundred years ago and here they are in hundred twenty, thousand in Arabia and the camps they also Campbell's it's kind of interesting that such large animals with Aaron. It begs the question were these humans following them where they attracted them. Going back to the, we talked about it being about one, hundred, twenty, thousand years old. There's some question about the date but if that were cracked, is there anything particularly Gordon about this time human history about what we know about migrations that we could link these prince two? Yes. So what is really interesting is that genetic evidence says that everybody outside of Africa. Came from migrations that happened in the last fifty to eighty thousand years. So this state predates that we happen to know that early Homo Sapiens were in the Middle East pretty quickly after this or at the same time they're fossils in caves. At school and cough so that our early sort of product Homo sapiens. So we know humans are at sorta suggests that because we don't have DNA that dates back this early these were failed migrations. These were members of the human family that went out they weren't shelled migrations for them they lived, but they did not contribute to the gene pool of letting people today that's one hypothesis but it also shows that there's more complex story of groups of humans migrating out of Africa constantly whenever the weather excitement is right that it's three to nothing that they can get water follow animals to meet and trek. Africa. They can cross the desert. It looks like humans were doing that whenever they could and so how do they contribute tour ancestry today a really interesting question and how many different kinds of hominids out there. Thank you so much an thank you. Sir,
What are the origins of English
"Think if it is a bunch of. It is probably a bunch of women, MOMS and aunts on the island of England. That's probably the people who invented the English language and they were called angles. So they didn't even call English. They called it anguish. My Name's Tom Howell and I used to write the Oxford Dictionary encounter and I wrote a book called the Rude Story of English and it is a history of some dudes and some woman thousand five hundred years ago trying to invent the language. So in a sense when you learned English. From the older people in your family. They are inventing English in a way because that is going to be a bit different. From the English that their grandparents spoke and then their great grandparents spoke and so on and so on and so on. Until when you go back far enough, it would be very difficult for us now to understand like great. Great. Great. Great. Great. Great great grandparents, saints which other think of how friend and neighbor are spell differently neighbors eat before I, friend is I before e friend came from one place where they said free owned once upon a time and neighbor came from another place where they were saying. It was actually called a near Ghabbour. You know has GM neighbor Mrs Weird thing we don't pronounce it now. It's just people stop pronouncing it properly but. Once upon a time, they would've been like, no, it's wrong to say neighbor without Jeanette they would have been like the correct way to say that is Nia Gabor because it was a boor who lived near you. So generations go by people make mistakes people say things a bit differently. People put on funny voices. Things Change. Now we say neighbor instead of new? Kabar I guess it is. The English is so complicated because it comes from all around the world. Yeah. What recalled English today like if you look up a word on the Internet to find out where it came from could come from anywhere. Like bungalow comes from India but you know even if you went back all the way to what the angles were saying, their language also came from all around the world like their language came from. Iraq and India and Russia and all kinds of weird places like people have been talking to each other for at least one, hundred, thousand years. So all of us, any point in history might say who invented our language and the odds would almost be some not dudes some arts and mother's thousand, five, hundred years ago. kind of doesn't matter where you are. That's always kind of be the answer.
Neandertals Tooled Around with Clams
"Around one hundred thousand years ago in what what is now. Italy are nandor tall cousins. Wait it out into the shallow. Coastal waters of the Mediterranean Sea in search of clams. Big Grant the the molluscs from the sea floor and perhaps even died for them in deeper water and they also simply collect clams from the beach but the creatures weren't just food in a recent Study University of Colorado Boulder archaeologist Paolo Villa inner team report that neanderthals modified the clams hard shells into tools for cutting and scraping. The clam derived implements were found inside the grow today. Motion rainy a coastal cave. That was first rediscovered around eighty five years ago by examining wear and tear on the shells the researchers determined that about seventy five percent of the tool source material had been found found dead on the beach. These shows had been worn down from being battered by waves and sand but the remaining shells were smooth and shiny indicating that the clams lambs were still alive on the sea floor when they were gathered. These shells were also thicker and therefore might have made more durable tools so even though gathering clams underwater took more work than picking them up on the beach. The effort may have been worth it also found in the growth at any pumice stones volcanic eruptions that occurred to to the south of the site. Those stones may have been used by neanderthals as abrasive tools. The study is in the journal loss. One neanderthals else were making these tools than fifty thousand years before modern. Humans first arrived in Western Europe but neanderthal intelligence was dismissed by the scientific community. Munity during much of the twentieth century in recent years however evidence of their tool use and even artistic abilities has grown neanderthals hunted. That'd made cave art cooked with fire us boats and when fishing just last year for example research by villa and others found that neanderthals tolls living not far from the grocery knee. Site used resonant. He serves to attach handles to stone tools. They may have gone extinct some forty thousand years ago but it's becoming ever more clear that neanderthals were intelligent creative. People who lead fully human lives.
Who Was First on Earth?
"Today are mysterious past the first the people on Earth. Where did they come from? Leonardo Davinci. Tesla is dying these three in one hundred others over the centuries all with ideas. You were ahead of their time. Where did these ideas come from? Metal Staples at held Mexico's Ancient Pyramids together yet. Local indigenous business people had no knowledge of metallurgy. The NASCA wells relied on air pressure to bring water up from underground rivers and the unexplained tunnels on on the two thousand five hundred mile. Inca road that are carved through solid stone. How did that happen? How were these deeds? Possible where to disadvantage. What's knowledge come from could survivors of a long extinct species of Homo Sapiens have somehow passed on the tiniest spark of knowledge through DNA? What a silly question indeed based on science I guess not so silly before you dismiss this premise? Completely let's take a look at the evolution universe. Science would agree that the planet earth is about four point five billion years old to put that number two perspective consider that a billion is a thousand million and a million is a thousand thousands for no less than a century. It has been believed that the earliest earth was covered with the see of vocally magma however evidence of this of the rocks have either eroded with time or stay down underground inaccessible enter Zircon crystals. Not the man made versions but tiny crystals pulled from the Jack Hills of central Australia. The oldest of which have revealed that during the first five hundred million years so the planet earth was not covered with the see of magma indeed that it was cold enough for the formations of continents were above sea level. What is revolutionary is these ancient crystals have revealed that early earth and some aspects? Wasn't that different from today. These science-based facts are less than a decade old. That already gaining aning the respect of mainstream science in one four point one billion year old crystal carbon was found suggesting that life existed justed on earth. Three hundred million years earlier than scientists previously thought. Twenty years ago this would have been heretical. This carbon resembles modern carbon. Though this all adds up to the conclusion that early Earth was more hospitable to life than science thought and begs the question could could the environment of early Earth supported. Humans could earth's I people have crawled out of an ancient ocean. The primordial soup so to speak and evolved over the next two hundred thousand years if we run with that rough figure man and is developed brain may have been walking walking around over a billion years ago not two hundred thousand. But where's the evidence of a civilization that all the answer is. Where's I the evidence of anything? Over one billion years old science degree so there have been five periods of mass extinction. Four hundred forty four million years ago. When eighty six percent of all species became extinct? Three hundred seventy five million years ago. When seventy five percent of all species became extinct and in two hundred million years ago with the loss of eighty percent and finally sixty six million years ago when seventy six percent fell to extinction keep keep in mind that the tortoise of the Galapagos has evolved over twelve million years each of the known periods of mass extinction did not eliminate all all the species and some fossils remain science agrees that there certainly could have been far earlier periods of mass extinction and extinction say over a billion years ago? One that would leave. No fossils. Time would take care of that. If Homo sapiens were among the victims uh-huh of an early earth extinction. Of course there would be no fossils. But what are the carbon found in Australia's ancient zircon crystals and what of the advanced knowledge displayed by South America's earliest indigenous people. Where did they come from? Your guess is as good as mine and only time time will tell
How Do You Compare to the Average American?
"The financial profile all of the average American or more accurately profiles of many average Americans since a proper apples to apples? Comparison takes into account several factors. So we're GONNA approach this this by looking at the financial life cycle of somebody which of course starts with birth. Fortunately you don't have to pay for your own birth. That's good because because the average cost of a birth in America these days ten thousand dollars and that's if there are no complications whatsoever So let's jump ahead to one of the first experiences people have have with actually earning money and that is an allowance. How many kids get an allowance? And how much do they get law. According to a recent survey from the American Institute of CPA's as two thirds of parents get allowance and the average is thirty dollars a week. It's pretty nice. Isn't ages they say what ages they start giving they broke it down a little bit. Okay but what was interesting to me was far too five. Parents expect the children to do work. Some people feel like you should just allowance because that's how you learn how to be responsible And they expect at least one hour week of chores but on average children are spending five point one hours a week doing chores for their allowance. So let me just say that my kids are below average with my kids are not doing five hours. Where the tour? I don't even do five hours worth of chores in our house and I do a lot of chores in our. What are these are? Are these kids living on a farm like that's a very good question. Chores chores could be clean your room for us. It is dishes this. This is the number one joy that kids do and we're not even very good of making them. Do it. Put your own shoes on in the morning to dress yourself. Live at Downton Abbey. Everyone everyone here anyway. So there you go. That's allowance so that's money from your parents but you'll eventually reach the point where you can start earning money from other people and here we are talking about being a teenager but the emphasis is can because most teenagers don't according to a study by the Hamilton project. And the Brookings Institute back in Nineteen nineteen seventy nine fifty eight percent of teenagers. Were doing some sort of work. But today it's only thirty five percent most teenagers don't have a job which not even like babysitting reasoning or I I guess not then the factors for why this has gone down as number one. They say that teenagers just have more things to do. Like like more kids are doing More kids are taking classes over the summer. Also there's less low wage work more competition from older folks and immigrants. That said I have three teenagers and I'm not sure I quite vile this Mike. Especially in the summer my kids have managed to find jobs but regardless the majority of teenagers not working. What was your first job while so I used to cut before I was of age to be doing? I cut lawns in the neighborhood and Dan. I watered flowers at a local flower shop. Then sure I've told you this story F.. I faked my birth certificate so I could work in McDonalds when I was age. Fifteen instead instead of sixteen so I did that ric have I to you. It was your first job horrible paper route once where you have to go door to door and collect the money which I always hated to do you so I never did it so I never really got paid for thing. What about you so my first job? I I went to high school where you are expected to work like four hours a day so you go to class in either the morning or the afternoon and then you would then so what kind of like work at the school. Yeah you'd work in the school or you'd lurk working in nearby bakery or you'd work farm too so you could work on the farm. Some people had farm jobs or work on maintenance and the school So I worked for the principal symbol. Of course I was responding. I did a lot of you. Know entering in people's grades and typing let transcribing letters and just the office work so as like fifteen. I think started. Did you like that because I've often thought especially as a former elementary school teacher junior high teacher. I thought a lot of this education is wasted in the dish. It's been half the day like working out in the basically interning at different types of jobs because they're not learning so much in school. Yeah no I mean it was is one of the better jobs to have on campus. That's for sure. So did you. And your friends. I'll get straight a's no but we I mean we could. We could have definitely changed. All of our grades were honest asked by it was a religious school so God would have smoked in us we. We were well aware of the consequences for changing our grades. So we didn't do it got got it. At least I didn't what's next in life. maxine life is well. We're going real job hitting their well even before. Then you finish high school and and then what college you go to college. I should first of all point out that it's nice if you want to write so point out. First of all. The graduation rate from public high schools is now eighty five percent near an all time high. So let's go so how many people then go onto college sixty nine point seven percent according to the Department of Labor not everyone gets four year degree as some people go to college and they don't get a degree. People get the associates so when you look at four year bachelor's degrees and graduate degrees. It's it's between thirty five and forty percent of people who actually end up with a degree but almost seventy percent do end up going to college which of course brings us to one of the first major financial decisions. A kid has to make depending on how much their family is willing and able to pay and that is the cost of college so according to the College Board. Let's go over the numbers here for the two thousand nineteen thousand twenty year a four year your public in State Education Room Board Fees Tuition Twenty one thousand nine hundred and fifty for your public out of state thirty eight thousand three hundred and thirty four year private school forty nine thousand four hundred ninety dollars ice now. The College Board is quick to point out at those are the published sticker prices and that most people don't pay those they say that about three quarters of students receive grants that reduce the actual price that people pay and just just about every college these days has something called net price calculator. You go onto their website. You put in some basic financial information. It gives you a general idea of how much you would pay. It's not binding or anything but if you're thinking of a college go to the net price calculator and you get an idea of how much aid you might receive. That said. We all know that grants. It's an aren't enough. which brings us to the topic of educational loan so approximately two thirds of kids graduate with debt with the average being between thirty thousand and forty thousand dollars depending on which source? You're looking at repayment. Can Take Ten to twenty years. And according to the Federal Reserve one fifth of ours were behind in their payments in two thousand in seventeen. So you have to wonder is a college degree worth the cost well for most people. The answer's probably yes. College grads on average earn seventy I five percent more than high school grads but that said the Fed did find that college is not a good investment for about twenty five percent of graduates and several studies of people who have loans at found that the majority of people regret the debt and they wish they would have found some other way to pay for college either going to community college allege not going to the private school something like that but regardless of how you pay for it you do graduate head out of college time for that first job. How much can you expect to make while starting salaries these days around fifty three thousand dollars? But who's paying you the most well engineering degrees computer. Peter Science and math those starting salaries are between sixty five thousand and seventy thousand math math. Now that's crazy math data that everyone is so hot with the data. One loves the data exactly so since we just brought up salaries. Let's expand this beyond starting income income in general in the United States. What is the average or the median household income and the United States and the answer is whereas the sixty three thousand one hundred seventy nine dollars? that's what you said family or average average average household household income but there are a lot of factors that would tournament starting with where you live. So the highest incomes are in the northeast. Meeting is around. Seventy thousand thousand filed by the West Midwest and the South South is lowest at fifty seven thousand. Being married helps. The median income for a household with a married couple earns. Ninety three thousand six hundred dollars Also age is a factor the households will make the most are in the forty five to fifty four age range with a median income of eighty. Four thousand four hundred dollars. We've talked about this before. Where income generally peaks at some point in your late forties or early fifties? Finally just just give me an idea of where your income puts you in relation to the rest of America. Here's how the income dispersion breaks down so if you make thirty seven thousand dollars you're in the bottom thirty thirty percent again. Median sixty three thousand. If you make one hundred thousand year in the top thirty percent hundred eighty four year in the top ten percent and to be in the top five five percent you make two hundred and forty eight thousand dollars. That's generally how income breaks down.
A Star In Orion Is Dimming. Is It About To Explode?
"One of the brightest stars in the night sky is named beetlejuice is about six hundred fifty light years away which is pretty close in outer space terms and if you've gazed eased up into the night sky and seen the Constellation Orion. You've seen beetlejuice before. So if you were to look up at it you would want to start by finding the three stars that make a nice little line that we call a Ryan's belts and then beetlejuice is as you're looking at it. The shoulder of Orion on the left. Emily Leveque is an astronomer at the University University of Washington who studies stars like beetlejuice which is known as a red supergiant supergiant because this star is enormous much bigger than our sun. If if you were to put beetlejuice where our son is it would swallow up all of the planets out past Mars and because it's so massive it means that it goes through a very different sort of life experience than our Sun will which brings us to why we're talking about beetlejuice right now. In recent weeks astronomers have noticed that beetlejuice. It's no longer appears to be one of the brightest stars. In the night sky there were sort of quick reports put out from people who monitor and observe beetlejuice very frequently. Saying you know it's getting dimmer and dimmer it's starting to get closest to the dentist we've seen there's also big dedicated networks of amateur astronomers that keep very close track of the brightness of stars like beetlejuice and they started noticing the same thing when we called Emily. She was preparing for this big astronomy conference in Hawaii Hawaii and she thought there would be a lot of buzz there about the dimming of beetlejuice beetlejuice is going to be a big topic. I'm sure especially family. She told us a Ryan is her. Favourite Constellation Constellation. But actually you don't have to be a pro astronomer to see what's happening with beetlejuice you can look for yourself at one point. beetlejuice was one of the brightest rytas stars in Orion. But now not so much so if you were to go up and look at it tonight it's dimmer than the star in Iran's right knee which is Ri- Joel and it's about equal in brightness to Ryan's other shoulder which is a star named Bella tricks so the fact that we can see with our eyes. That got noticeably dimmer really caught a lot of people's attention and then spiralled as just a wow. This is a really interesting and compelling thing changing sort of on our timescale in the night sky. So what's going on as we'll explain with help from Emily Leveque. Scientists have a few theories for why BETA disappear so dim and in the most dramatic explanation. Is that this star could be about to die. What's known as going SUPERNOVA? It would look pretty epic. I'm Emily Kwong filling informatics format today. This is short wave the daily science podcast from NPR. So here's the thing there's been quite a bit of speculation that the reason beetlejuice getting dimmer is that it's about to go Supernova. That's the big explode e end to the lifespan of a massive star and while dimming can mean that's about to happen for reasons that will get into it's not the most likely scenario for beetlejuice but first we had to clear up something with astronomer. Emily Leveque is this very cool star named after the tenth highest biased grossing film of One thousand nine hundred eighty eight. I'm pretty sure that it's the other way around. The spelling is different and sometimes here astronomers pronounce a little bit differently. Bentley will say beetlejuice instead of beetlejuice. Three times But it's actually derived from a Arabic name and there's I think some disagreement on what exactly it means but either means the arm of Orion or the hand of Orion or the hand of the hunter because the total constellation is looks like a person hunting. It's the only can I be honest. The only constellation I can ever successfully identify. Isn't that belt. It's very telling so I'll admit it's the easiest constellation and for me to identify to This is one of those. Well kept secrets of astronomy. A lot of us are embarrassingly bad at finding things in the night sky because we're used to looking at things that are so so dim that you can't see them with their own eyes and our telescopes have amazing computers. That can help us find things so we'll occasionally go out and look up and do just what a lot of people doing fine like that familiar. Little Line of three or another easy constellation to get our bearings A.. Let's talk about how astronomers such as yourself people who really study V. Stars have noticed something different about how beetlejuice looks in the night sky. How does it look different? So I will say we've been monitoring the brightness of beetlejuice for decades its and we've been measuring its brightness very frequently and we've seen its brightness change with times we've watched it get brighter and dimmer. This just caught people's attention because it was close close to the dentist that beetlejuice has ever been and what could dimming like this indicate so our guest right now is that what we're seeing is a combination of a few behaviors that we see in red super giants and that we've seen before in beetlejuice. The just happened to be coinciding. So we know that stars like beetlejuice. Have big support of boiling convective cells near their surfaces seal sort of get a bright hot spot and a slightly dimmer cool spot and it's entirely possible that this dimming is due in part to those convective cells we also know that stars like beetlejuice will actually shed off some mass from their outer layer. sobel sort popoff. The outermost layers of the star when that mass hits the Interstellar medium. It'll condense into what we call dust and dust dust in space kind of does. What does here it blocks light and gets in the way and can be a little bit of a nuisance but it would make star look a little bit dimmer if it then had a little veil of dust around it we also know that stars like this can pulse eight a little bit so their outer layers will sort of squeeze in puff out just due to instabilities in those layers and that'll also affect how bright the star looks so? I think the current guests is that we're seeing a couple different behaviors in beetlejuice. That on their own aren't too to strange. That just happened to be coinciding to make the star look especially dim so just as a thought experiment say beetlejuice is going to go Supernova. Br Nova how would we know. And what would it look like. So first of all the light that we're seeing from beetlejuice was emitted by the star about six hundred and fifty years ago. beetlejuice is a six hundred and fifty light years from Earth so when the light emerges it comes toward us as fast as it can but it's moving at the speed of light so looking at Beta Jesus a little bit like looking back in time to what the Star was actually doing six hundred and fifty years ago in terms of whether we will see beetlejuice go Supernova in our lifetimes beetlejuice and other massive stars like this kind of follow a live fast die young philosophy so they live about ten million with an m years beetlejuice in particular we know is moving into a later stage of its life because it is so big and so red but that could mean that we still have one hundred thousand years before it dies and produces a Supernova If it did though say we all went outside tomorrow and we we were seeing the light arrive from babies dying as a Supernova six hundred and fifty years minus day sometime in the Middle Ages. Let's say okay it. It would look pretty epic we have some records of other SUPERNOVA. That happened in the Milky Way and their appearance parents is incredibly dramatic. What we would see is Bagel juice getting brighter and brighter? Because we'd be seeing the incredibly bright signature of the SUPERNOVA explosion explosion. It would actually get so bright that if beetlejuice was up during the day we'd be able to see it during the daytime alongside the sun and it would last for for weeks and I think that if beetlejuice were to go supernova tomorrow and we saw it at night it would be comparable in brightness. I think to the full moon. ooh Wow we'd be able to see are shadows based on the light from the SUPERNOVA. Okay so what would it look like for beetlejuice more of a going collapsing inward on itself. I I am more of them. Exploding outward with star debris scattering across the universe. What what does it look like for Adl juice? It's a good question in it. We think that it's a bit of both both okay initial disruption comes when the core of the star collapses and depending on the type of star. And how much mass is in that core. It'll collapse into to a neutron star or a black hole after that collapse all the outer layers of the star come falling in toward the core and then bounce back off in a sort of rebound shock and that shock is what we see as a Supernova and what we would call a supernova because we see this outward blast of material you know new gas slamming into the interstellar medium and getting really bright and it looks to us like an explosion but it originally did start as a collapse. It's why I try to avoid saying that a star exploded as a SUPERNOVA. Because it's not to be the pedantic scientist it's not quite the first thing that happened in the star. But it's a bit Moroccan role as a turn of phrase. Oh yeah how would you so. This star is a part of your favorite constellation or Ryan and how would you feel if if indeed it we're we're going SUPERNOVA. I would be psyched. And I think some people expect that we would be very sad but it's a very exciting citing transition to watch and this would be one of the best studied stars we have available to US producing a Supernova. which right now is a process that we're you're still trying to understand we'd still be able to see the Supernova as it happened and then faded away these stars also leave behind what we call supernova remnants? So they're these these beautiful multicolored gas clouds that show us the dissipating material from the star. So it would be this amazing font of data and new ways to understand stars so I think it would be incredibly exciting.
The Real Paleo Diet: Roots and Tubers
"Paleo Diet is a popular high protein diet that that aims to mimic what our hunter gatherer ancestors aid. But what we buy at. The supermarket doesn't quite approximate. Those ancient foods take for example star Lily roots heard heard of those things. Lynn widely is an archaeologist at the University of the voters round in South Africa. Her team recently discovered the charred remains of star Lily. Roots in South Africa's border cave hunks of roasted root that date to a hundred and seventy thousand years ago.

Atmospheric Carbon Dioxide Hits Highest Level in at least 3 Million Years
"In our science fact of the day this just in according to the world meteorological association no you know flaming left wing think tank the a this is the W. ammo the literally the world meteorological association atmospheric levels of carbon dioxide CO two are now at the highest ever in three million years now that is longer than human history human history only goes back a couple hundred thousand years so atmosphere CO two levels right now are higher than when Lucy was around right the the pre human and a higher than when Lucy's ancestors were around getting Lucy was only about a million or so ago all of which means that our children and grandchildren can expect temperatures to continue to rise more extreme weather more sea level rise more destruction to marine life more destruction of land based ecosystems more death of insects and and stuff at the bottom of the food chain which then echoes up so that the birds die and and we're saying this right now you know sixty seventy percent of certain kinds of birds particularly the insect insectivorous birds drawn from our planet we're looking at at at an insect apocalypse right now and and this is just the very beginning we have not yet even hit one point five degrees Celsius increase in temperature over the bass line and the pre industrial base line I mean we're just about there but we haven't quite hit it and the bottom line what what all these climate scientists are saying is is that we have to stop it right there I can't go any farther and yet what is the industry doing right now and and in on the right wing media that is that is supportive of industry while they're making fun of the stuff I mean Michael Mann for example the the the scientist he's been a guest on this program many times as a brilliant easy university of Pennsylvania sciences he's the guy who invented the cop the hockey stick conception of the SCO to going up that Al Gore popularized bed professor of cleans climate science or atmospheric science or whatever it is add to Penn state university one of probably a top five climate scientists in the world Michael Mann me was made fun of by the competitive interest enterprise institute in their blog ran Samberg wrote that well first of all they they attacked Michael Mann they said that his science was nonsense and and that is so Penn state did an investigation because there was all this ball Rollin publicity Penn state did an investigation what they found was that he was totally stand up everything he said was true and the way he said it was fine and though he published it was in compliance with scientific rigorous scientific standards reviews stuff so the compatible devices that is one of these right wing think tanks in quotes it really just a propaganda show operation for industry guy name brand Sandburg wrote that Penn state had quote covered up one two in by Michael Mann and characterize man as quote the Jerry Sandusky of climate science because he had quote molested and tortured data in service of politicized science and then not a blog posted by hosted by the National Review online the national reviews the magazine that William F.

How Did We Miss This Week's Shockingly Close Asteroid Flyby?
"An asteroid as large as a football field is just flying past the earth with astronomers not detecting acting it until literally just a day before its closest approach. The giants space rock thought to be up to one hundred and thirty meters wide came within sixty five thousand kilometers of earth on july the twenty fifth in nominal terms. That's about as close as it gets. The asteroids being catalogued as twenty nine. Okay the european paint space agency says this near earth objects close approach illustrates the need for more eyes on the sky was able to observe the asteroid just before its fly by requesting requesting to separate telescopes in the international scientific optical network is on to take images of space rock the observations allow strana missed the determine the asteroids exact back position and trajectory yesterday it was i the technical the day before its closest approach by the southern observatory veneer of asteroids research observations of twenty nine thousand nine okay with an independently confirmed by other observatories including the chiba radio telescope in puerto rico and third telescope in the ice on network following following its discovery with knowledge of the astros would have been in the past based on its current course and by manually searching for it by existing images were found in the past is is an atlas skysurfer archives it turns out birth said they had in fact captured the asteroid in the weeks before it's ultra close encounter with earth but the space space rock was moving so slowly it appears to move just a tiny amount between the images and was therefore not recognized as a near earth object neo and hence the seriousness of the threat <unk>. It wasn't appreciated of course astronomers now of an attracting thousands of asteroids across the solar system so why was this one discovered so late will unfortunately originally currently there's no single obvious reason apart from its slow apparent motion across the sky before it's close approach twenty nineteen okay travels in highly elliptical orbit taking it from within the open of venus out too well beyond that of mas this means the time it spends near earth and therefore time it's detectable both current telescope capabilities is relatively short modules towards the size of twenty nine. Okay i relatively common throughout the solar system but they impact on average only about once every one hundred thousand years or so still an asteroid like that hitting a major city or urban area would cause major devastation destruction based from its current orbital path through the solar system the asteroid one come close to the game for at least the next two hundred years.

Is Permafrost Really Permanent?
"Brain stuff lauren Bogle bomb here in two thousand ten. A woolly mammoth carcass was discovered in Siberia near the coast of the laptev sea nicknamed Yuka. This specimen of the long extinct beast died around twenty eight thousand years ago yet her body was astonishingly well preserved complete with patches of reddened for brain that was largely intact and nucleus like cell structures so how did her body lasts so long without rotting away the short answer is Yuka was frozen but not inside some glacier iceberg after death you can became encased in a layer of what's known as permafrost. Let's break down what that is as we know. Water freezes at thirty two degrees Fahrenheit four zero degrees Celsius permafrost is any ground materials such as soil sediment and rock that remains at or below freezing temperatures for at least two consecutive years. It's about twenty five percent of all the land area in the Northern Hemisphere is known to contain permafrost. It was American paleontologist Simone W Mueller who originally coined the term permafrost appointment two of the words permanent and frost despite that name permafrost doesn't last forever thanks to climate change. It's been been thawing in large quantities. This has serious ramifications for the environment and the economy generally speaking permafrost tends to occur in places where The average air temperature is zero degree Celsius or lower every year. According to the national snow and Ice Data Center most of the Northern Hemisphere's permafrost sits between the high high latitudes of sixty and sixty degrees north Siberia Canada Alaska and parts of Scandinavia are loaded with this frigid turf further south permafrost tends to be found in high elevation areas like the Tibetan Plateau and this was elps permafrost isn't as widespread below the equator but it does underlie parts of New Zealand the Andes Mountains and Arctic adjust as its locations vary so does its composition. It's not uniform. Some sections are ice-free while others are made up of more than thirty percent ice likewise the depth age and extent of permafrost. Ken Vary widely oftentimes permafrost permafrost sits beneath an active layer of ground that is a layer that thaws and re freezes seasonally. The permafrost itself can measure anywhere from less than three feet. That's one meter thick to more than five thousand feet or fifteen hundred meters thick and it can get Patchy Northern Alaska occupies a continuous permafrost zone that means permafrost underlies more than ninety percent of the local terrain but at lower latitudes. It's a different story pretty much everything south of the Brooks mountain range sits discontinuance tenuous permafrost zone here permafrost resides under a smaller percentage of the land surface. That's partially because as counter intuitive as it may sound snow. Snow is a really good insulator so when thick blankets of snow stick around all year long they might keep the ground too warm for permafrost likewise in spots. That's where permafrost already exists insulating layers of surface level snow are liable to heat it up but while snows and impediment. Pete is a boon widespread in and around the southern Arctic. Pete is a kind of ground material. That's made up partially decayed organic matter like mosses or swamp plants by and large the. Ground beneath it is kept cool shielded from solar heat this pete safeguards permafrost evergreen forests lend a helping hand to their thickly thickly needled branches pine trees limit the amount of sunlight and snow that hits the surface in the process the evergreens help keep permafrost thawing so permafrost is common below the clustered pines and high elevation high altitude areas the arrangement is mutually beneficial since liquid water can't sleep through hard permafrost. I it acts like a drainage barrier unfrozen water. That's absorbed into the active layer gets trapped. They're barred from travelling deeper into the earth. This water sustained some of the plants that live at the surface although not all permafrost sticks around more than a couple of years some is quite old at minimum. The permafrost in prudhoe Bay Alaska is thought thought to be five hundred thousand years of age and some of the permafrost beneath the Canadians Yukon territory could be more than seven hundred thousand years old inside the ladder scientists. It is found in ancient horse leg complete d._N._A.. Samples Permafrost can keep all kinds of organic matter preserved over long periods of time in two thousand twelve Russian scientists is regenerated live plants from ice age fruits that have been encased in permafrost for about thirty thousand years unfortunately as permafrost thaws the trapped organic organic material decomposes releasing carbon and methane into the atmosphere those gases exacerbate climate change and the bad news is according to a twenty nineteen can study published in nature communications various permafrost deposits around the world have warmed up by a couple of degrees between the years two thousand seven and two thousand sixteen right now approximately one point seven billion tons of carbon is trapped in permafrost scientists. Don't know how much of this will be released into the atmosphere. If current trends continue continue or how quickly it will In the city of New Orleans gresh alone more than one hundred residential buildings have been damaged because the one solid permafrost beneath them is softening the warming permafrost has has also triggered landslides drained lakes and torn roads apart. It's yet another reason to be concerned about our contributions to climate change but to end on a positive note remember the woolly mammoth Yuga found in Siberian permafrost in two thousand ten. She was so well preserved that an early twenty nineteen scientists were able to extract eighty eight eight nucleus like structures from her cells an attempt to coax them back to life. The team injected the nuclei into mouse ovarian cells and while the cells never fully divided divided they did complete the process called spindle assembly which is a step where chromosomes attached to spindle structures before the parent cell breaks into two daughter cells.

This from John Mark, listen, he's supposed to ask mom before you play on the phone and this from Christopher Mark run about one thing that Democrats need to stop talking about what they were in favor of many years ago. What happened many years ago and how much they thought about it many years ago? And they do the border right now. I'm always delighted always delighted to have. Opposing points of view. I think it's interesting. Engage. Unfortunately, it's hard to do that. It's hard to part because as you see it has the potential almost every single time of devolving down into a a bunch of personal attacks and name calling. So you walk away from talking about the issues and just start calling names. I'm not going to do that. Maybe once upon a time, but not just the the time shift too serious, and we have too much to do Nancy Pelosi, listen carefully here, folks, Nancy Pelosi. Yesterday. Was a raise the wage event. Something we're going to be doing here in this state. She says the Democrats will work to keep their promise of creating a livable wage for all Americans and to strengthen the middle class, listen carefully. We all know that the Neal causes the backbone of our middle class in our country and the middle class and those who aspire to it those we are here to work for and that middle class is essential to the strength of our democracy. For those of you who might have gone through a moment of fuzzy on your radio or something let's play again, the really important part. I mean, the key part of what MS Pelosi just said we all know that in the middle class is the backbone of our middle class in our country. We all know that the middle class is the backbone. Of the middle class in our country. I'm not quite sure I understand. So what what the speaker seems to be saying that there's one class of individuals that is the backbone of the middle class. In this country. But I can't remember miss Pelosi. What class would that be who's the backbone of the middle class in our country? Okay. The middle class. All right. Good. Thank you for clarifying that I was so confused for moment. They are just absolutely. So confused. Can we cut six up again place because I know make a twenty six. No, I'm sorry.

We all know that in the middle class is the backbone of our middle class in our country and in the middle class and those who aspire to it are those we are here to work for and that middle class is essential to the strength of our democracy because the middle class. Is the backbone of the middle class of this country in the middle class the middle class. They're the backbone of all the classes in this particular country.

"It is to our great misfortune that we are being presented with the responsibility of dealing with existential risks at this point in human history. It was only perhaps fifty to a hundred thousand years ago that human started being born with the full package of behaviors and intelligence that makes us uniquely human. Our ability to reason and think abstractly to imagine different futures are -bility to organize imagine. If we had another hundred thousand years to continue to evolve before the eggs essential risks will have to address appeared on our horizon, but that's not how the chips have fallen. Instead, it is come upon us while we were in what Carl Sagan called our technological adolescence the most dangerous face on the way to technological maturity it is up to those of us alive in the twenty first century, we bear responsibility for saving the future of the human race. And we have come up with plenty of reasons why we shouldn't. Or more to the point. Why we won't? Probably I among them is that the chance of one of these risks befalling us is so small so utterly remote. Not even worth considering. It is true that the chance of existential catastrophe like an altered pathogen escaping lab in creating a pandemic is extremely room up, but as more labs conduct more risky experiments around the world, the probability of that remote risk begins to compound and the same is true in other fields as new particle collider run higher energy experiments as more companies deploy more self improving algorithms onto global networks. What was once a mere remote possibility exit central catastrophe becomes decidedly less remote? I think there are various forms of arguments against dealing with existential some of them much better than others. So I think the Hudson the signs of the action. Oh, it one path or it has never happened before that is a really bad. But it's of course, psychologically wrote the coma because his fits with Colin Tobias. That was Anderson Berg, the philosopher from the future of humanity institute. In addition to all of the advanced behaviors that we humans has evolved that served us. So well, we also operate using some extremely ancient techniques to shortcuts that allow us to deal with everyday life, but can breakdown going more faced with things that are out of the ordinary. What result are called biases. Take for example, being presented with the fork in the road, given that both paths look equally inviting we might have trouble choosing. But say we've been presented with the same decision. Elsewhere with other forks and other. Roads before and we've usually taken the left path since nothing bad happened to us all those other times. We've chosen to go left. We would feel pretty sure nothing will this time either. So we head down the left path this time to whistling without a care in the world, totally unaware of the family of hungry bears ahead. Our cognitive biases can make us overconfident suspicious of new things optimistic pessimistic frozen within decision. We are you could say a little hamstrung by them. But even when we managed to overcome our biases or set them aside, which we will need to win were dealing with existential risks. There are still plenty of other reasons we can come up with to avoid addressing them for one even discussing this type of risk can be dangerous. Such talk can have a chilling effect on a field that's struggling to establish itself as Eric Drexler found when he led the gray genie out of the bottle and engines of creation. Talking about things like AI becoming super intelligent in taking control of our world can really go a long way to turning the public off from the idea of scientists working on building self improving thinking machines, besides as most machine intelligence, researchers will point out at this stage in its development. The field is capable of producing a machine that's perhaps as smart as three year old or even if it is advanced it's advanced it just one thing like finding patterns and medical charts or identifying cat pictures. We don't need to worry about. In other words. This argument seem shortsighted if it is the case that we're at a point where we can still fully controller artificial intelligence. The now is the best time to plan for the potential future outcomes, they might bring so that we can ensure as best as we can that they'll continue to remain under our control..

Well, that's that's sort of what kicks kicks this off in a sense that, you know, this is sort of the this is now with a pretty solid finding that's ten thousand be seeing. It's coming around the time that primitive hunter hunter-gatherers are just beginning to domesticate, corn and wheat. So it's like how could this possibly be? That doesn't have go package.

"I also the invasion into our genomes genomes, many creatures from viruses as well. What do we something like eight or ten percents of our genome is actually from viral sources and dodge Anais retroviruses somewhere between eight and ten percent. So that's about four times more DNA, which actually makes us male. We move virus than we all man. I'm not going to follow up on that festive if you that's just bring bring it back to to humans because that's what we have to power through the whole history of life on earth hair on. So we're interested in the notion of what happens, these major transitions. And then something happened to us, which I think is a fundamental interest because we quite a anthropocentric species, understandably, which is at some point in the last hundred thousand years we become behaviorally modern, we become the creatures that we recognize today. Now what can we say that I, but then I want to move on talk to Danny about this as a neuroscientist. What can we say about what happens to our brains in the last hundred thousand years, which made us who we all. I think this is really interesting. In ongoing question. It's been very difficult to pinpoint any specific genetic changes that are associated with this transition. That probably means that it's more complicated than a single mutation that happens that sweeps through the population that makes us distinctly. Human different from any of our archaic common ancestors. So this really is a question about complexity. Were there many low frequency mutations that just happened to combine interact and a particular person in just the right environment? I don't know. But as we start diving into inch genomes and anatomically modern individuals from archaeological sites, I think we'll get closer to seeing that answer to all brains from the mentally change. We don't think for two hundred two hundred fifty thousand years, maybe three hundred thousand years, but I'll behavior has radically change in the laws. One hundred thousand years. We don't show precise dates of when that transition that code, but what can we learn about the emergence of our modern human behavior from the structure of our brains when we think about the human brain and what makes it maybe different than other brains, there have been theories that suggest that it is has to do with the number of neurons that are present in the brain. And that's sort of been set aside at this point. There was also a theory that it's the size of the brain, and that's been set. to. I think the current ideas that are prevalent at the moment are that it has to do with the complexity of the interconnections between neurons and other cellular components inside of brain tissue that allow for the complexities of behavior, the characterize us as humans. But crucially that we, as the human brain is the most complex structure in the known universe. Now, he's not. He's not a reasonable thing to say, is that a useful thing to say the true? It depends if you talk to an astrophysicist or not. Astrophysicists on this panel say, let's just say it's true. What does it mean in terms of the organization of the brain? Where does that complexity arise from the complexity arises from the fact that that individual components inside of neural tissue may each have different functions, but then they have to communicate that information to other parts of the cortex source of Portugal areas. So that pattern of communication becomes important. Just like the pattern of communications between us as humans changes the way that our country's work, our culture works. Our societies work the history of neuroscience and also often the way we talk about brains in this sort of public schools is we tend to think about them as sort of components. There was an area which does this. There's a speech center. There is a sense of emotions, old old bits of the brain, which control things like breathing, is that still a useful way to think about brains compartmentalized in in that manner? I think that there has been a huge success in the area of what's called brain mapping, which is trying to identify. What each of the pieces of the brain does particularly at the large scale. So regions of the brain that are important for auditory function or visual function or movement. However, I think it's it's a bit like mapping out a country, right?.

"And this is not just current now. I should like this literally for two hundred thousand years. Women were property. That's nothing right. It's only been a few thousand years and one hundred years where women have had the right to vote in most, right? So for two hundred thousand years, women were property and this is living in the limbic system and the nervous systems of all women, right? And now there's kind of a waking up a like a collective waking up of the feminine, and and men are confused because all of a sudden this not just your anger about your life and your relationship to men and all of that. But generations of beat raped, tortured, and you know, and and. So the first thing I I'm trying to do is get men to see that and really feel like make a practice now of feeling deep into her pain and not just her pain, but the collective pain of the feminine. And if you can start from there, men can take Dell. Well, you know, I just. Axes exit through intellectual. Well, yeah. Okay. So painful, but I'm paying a rat, right? Whatever guys are thinking. I'm just saying I'm doing this for her and that it's not that bad, but we are talking about the suffering of women like it is out there. It's been there. We feel it. I just I love that you bring. I had an exercise on Saturday night where I had all the men stand in front of the women. We ended that practice sink. You breath, look into her heart, you know, sync up with her. And then I had I had the women say no in every possible way for as must have been ten minutes and they were yelling, no, they were begging. No, all the knows that they couldn't say and the men were just weeping and the women were screaming, and it was just this really beautiful experience of men feeling how much pain is in the feminine body. And so you, I guess you could try that home. I think. You should try this at home. Yeah, you have to decide to feel it right? It doesn't. It's not hard to actually feel somebody more once you decide to feel more, you just have to make an intention to feel more. And of course the exercise that we talked about that. Yeah, no, definitely. I remember doing something some of that on your retreat. Yeah, yeah. So I start there and then and then from there, then you can start to feel like, you know, where is she a? Yes and where she? No, right. But once you once you can feel like, hey, I'm in a lot of pain, and I actually have to be super impeccable for her to trust me and super present for her to trust me because she's carrying not only mistrust of her whole life, but like for all women in a certain way, end generations back, I don't know if you know this book, it didn't start with you. Now. Great book about epigenetics out. Trauma gets passed down from generation to generation. It's really, really freaking good book that anyway. So if men are doing that than I'm just training them to start to get in sync with what women are going through, like this massive waking up. And if you do that and then you go out on a date like I when I was thinking about this, I've thinking like, would you know women are dying to be thrown up against the wall. It's great example. How would you like me to come. He was okay. If I throw you out. I just. Yeah, so so men have to try to feel like, where is that moment, where her eyes and her body tell me, throw me up against the non verbal consent, totally non non blog about and lot of posts on your website to check up. Let's explain that the nonverbal, what you're saying reading into it, the body language. So let's say I'm on a date with scouting or listen on a date and and I'm, I don't even have to let her know, but I'm slowing down. I'm looking into her eyes. I'm looking deeper into her. I'm trying to breathe with or like you just took an inhale with. Attentive way. Not right now I'm doing this thing, but you could actually it's accessible successful. Do it. Eddie moment at any moment, everyone should slow down all the time sexually and even date. So yeah. Okay. And you don't have to brag about like a baby..

"The science he dropped some sourdot history on the group nobody knows exactly where and when sourdot bread was first invented the earliest evidence we have for making bread comes from a site in africa archaeologists have dated the remains of that bread to a hundred thousand years ago it was probably made from pounded sorghum and water and baked on a hot stone we're not sure whether that was a sourdot or not but it may have been something like the indera that ethiopian still eat today had sort of spongy in bubbly in those bubbles or created by a community of wild microbes just like today's sourdot basically if you combine ground up grain something like wheat with water and you forget about it and leave it alone eventually it starts bubbling and that's because a bunch of different microbes usually a combination of fungi like yeast and bacteria lick lactobacillus the colonized the mixture feed on the flour and that is both the start of beer and a sourdot starter there is hot debate among historians about whether humans i figured this out because they were making boos or making bread i'm on tv beer to be honest but short of cynthia finally inventing her time machine we will probably never know either way humans figured that this wild bubbly mix made their flat breads into breads the non flat kind these loaves of bread would have all been soured owes there was no other way to make bread rice so full thousands of use soured uwa's being used by each and every baker old person that would big brits and even before people knew what microbes were they were already caring for these wild communities of bubbling beige glucose feeding them with more flour and water to keep them alive and happy they figured out that you only need to add a dollop of starter to your doubts eleven it which means you can keep the same starter going for years and years decades even just by feeding it with flour and water and using a little bit of it every time you bake it becomes like your own personalized wild limiting mix that you can keep alive and use it again and again and again other people develop variations on this approach in ancient greece for example plenty the.

"Listen as it he save appears less than one hundred thousand years ago research published in 2011 shows that neanderthals had the ability to create in control fire so does the fact neanderthals could manipulate fire to produce tar prove they weren't as dimwitted as we like to assume scientists have been curious about the process neanderthals used to make their glue a new study published in the journal nature scientific reports suggest three different ways neanderthal tar could have been manufactured after all it had to be produced this stuff wasn't just secreted from trees growing in the forest but how difficult was making tar tar making is definitely a process no matter which way you go about it the research team figure that out through a fancy bit of experimental archaeology they devised three different potential methods of extracting sticky stuff from birch park the ashish mound method where tightly ruled layers of birchbark are covered in ash in embers deep pit roll cigar roll method where one end of a bertril is lit and placed burning side down into a small collection pit and the raised structure method where a birch bark container was placed in a pit beneath in organic mesh which holds loosely rolled bark that is then covered with earth and fire after recreating the three tar production methods the scientists assess each according to three criteria the yield temperature and complexity the team found that though the simplest fastest method the ash mound method yielded just a piece sized amount of tar the most complicated timeconsuming method that's the race structure method produced fifteen to twenty times more and was also the most efficient they also observed that regulating the temperature of the.

"And to give it a lot more thought and to see how that would've how that would have happened well when you you look at it what you see is this the sun is type of star known as a yellow dwarf most yellow dwarfs have sterile planetary systems because they explode out ferocious waves of gamma rays every few hundred thousand years we know this because we see them doing it in in in out in in the galaxy now hours does not we know what dozen because we wouldn't be here if it did it is cers try kingly benign compared to most of its sisters are brothers depending on how you look at it again earth is just in the exact lease exact center of the narrow fifty five fifty thousand mile deep habitable zone around this star third the moon which it emerged out of a huge impact you know with the crater on earth the earth was left behind on earth that is of by the moon it's called the pacific ocean that was a big impact without the moon to slow the rotational winds of earth by because it's at the perfect distance and this is the perfect size we would not be here there would be nothing on the earth more than likens and things because the wins naturally generated by the rotation of the plant would be too strong the moon acts as a kind of break if the gas giants out beyond mars weren't here neither would waive because we would have long since been destroyed by asteroids coming in from deep space and the moon is there sweeping up the ones that most of the ones that do get through with the result that earth his hit far less frequently by bull odds and large objects than any other planet that we know of in the solar system so it's like goldilocks planet in a perfect place and i just wonder and that gets me now to this idea the basic idea of the book which is so in thrall ing it's a little bit like the ancient aliens but it's much more complex than that in deeper them.

"Probably at five hundred thousand years ago or more so there was an expectation that they should be a homo sapiens line going much deeper than the forces we have at two hundred thousand years in ethiopia and so there's been expectation but the problem was the they were possible sapiens fossil older but they were very complete will they went well dated now with the re dating and the re study of a good we've got a very good collection of what seems to be a primitive sapiens and a good dyke at around three hundred thousand so i think it breaks the mold of what we but we thought we knew about sapiens but it conforms with really the genetic data of a much deeper history for for us similar now to history we building for the talks that is true that you've been saying for a while that you think that the origin of saplings would be earlier than two hundred thousand years ago but the the place the location is a is another watt complete surprise to me where we are thousands of miles from southern africa niece in africa which is wet typically we thought was the the nursery of hummus at happens that's right yes and i think you shoes being the there's been this volleying for supremacy between east african and south african the fact is that probably different parts of africa were important different times in the story of modern human origins and indeed our autumn origin could even go back to some western asia because we've gotta think where did the common ancestor live of us and the knee and a thomason dennis ovens.
