"mike darwin" Discussed on Your Brain on Facts

"And comments again so you haven't been ignored folks who've been communicating with me via via facebook. I just didn't know about it and I'll get caught up on all those shortly though shortly is how I do everything. SEAHORSES and their kin aren't the only underwater co parents. The African sicklers does what they do without benefit of a brood. Pouch after the females later eggs preferably on the smooth rock and the male is fertilized them. The female scoops the eggs up in her mouth where they stay until hatching. This process is called mouth brooding and several several species of fish do it. Some are maternal mouth brooders some are paternal while others trade off which is called by parental mouth brooding. UH regardless of WHO's parenting. The point is to keep the eggs safe until the little fry consumer way though some species will also let the tiny fry back into their mouth for a while. Oh like a kangaroo with Joey. What's normal for sicklids? Looks like an opportunity for the coup catfish like the namesake bird heard these catfish are brood parasites rather than going through all the fuss and bother of making a nest intending to their offspring. They get another animal to do it for them. mm-hmm without that animals permission or even knowledge the cuckoo catfish barges in on cyclic. Meeting eating some sick legs and depositing housing some of their own in the confusion as the sicklets tried to run them off. Catfish eggs develop faster and hatch sooner than the Cyclic X.. which start to hatch about about the same time the catfish fry need to start eating? The catfish intruders used their wide jaws and extra teeth to devour the new hatchlings head. I if they run out of stickler hatchlings they start to eat one another. It might be better down where it's wetter but there's mouth brooding on dry land to and it goes by by the name of Darwin's frog named for American writer and activist Mike Darwin. No of course it wasn't it was named for Charles Darwin. This South American American frog has a head that looks like a curling dead leaf to help it hide from predators and inside that leafy head is the next generation of their froggy. The family line when a female Darwin's frog lays her eggs. Her mate keeps careful. Watch until the tadpoles hatch then like a temperate and well-intentioned engined cronos the mail. Basically swallows his young squirreling away to grow safely in his vocal sac until they have legs and are ready to make a go of it unfortunately. Unfortunately one of the two species Darwin's Frog hasn't been spotted in the wild since nineteen eighty and researchers are nearly certain it's extinct the other species is in a precipitous decline and for once humans aren't the primary reason why instead the blame rests with the Chitral Fungus which is deadly to affiliates. And what if rather than Kinda swallowing the young Darwin's frog totally actually swallowed them. Well then we would be talking about about the Australian gastric brooding frog. Why is it always Australia? The Australian gastric brooding frog thought to be extinct. Since two thousand two who had a bizarre method of maternal care the female swallowed her fertilized eggs and incubated her young in her stomach. Her actual stomach for about don't six weeks per babys- go through their tadpole stage safe inside. Mom Stomach to later emerged from her mouth as fully-developed frog let's but wait if they're in her stomach why don't they get digested. The mother frog not only stops eating but also stops producing stomach acid. There seems to it'd be a chemical released by the eggs and hatchlings that inhibit the production of acid. The scientists don't know what that is. The mother would brewed about two dozen exit ago which by the time they were ready to be spat out could make up about forty percent of her total body weight. That would be like a woman who weighed a hundred and fifty pounds or sixty eight kilos lose carrying sixty pounds twenty seven kilos of baby in her stomach. It's not especially comfortable for the frog designed to do it either. The young frogs stretch the mother's stomach to the point that completely compresses her lungs forcing her to breathe through for skin. The baby frog. Let's normally emerge one or a few. What a time over a period of days as they become ready if the mother sensed danger though she'd give birth to all of them at once by vomiting them out researchers was once observed a female expel six little frogs all at once shooting them about forty inches or one meter into the air? All of these animal mothers. I have one thing in common. A male meat but a partner is optional. For animals capable of PARTHENOGENESIS SCIENC- Speaker Virgin Birth. It's not that the females are fertilizing their own eggs the eggs are able to develop without having been fertilized. Some animals like whip tail hill. Lizards are fully a sexual and don't need a male to give birth while there are also animals that can mate with a male but don't always do so everything everything from brine shrimp to wasps to sharks and even domestic turkeys. Scientists initially thought that parthenogenesis only happened with animals and prolonged. I kept that animals wouldn't have a need to do so if they weren't isolated such as the case of a Python in the Louisville Su who had never been in contact with a male male of her species but produced six snake babies over four years. They've since learned that virgin births can happen in nature even when there are males around like with the Australian stick bug who will drive away males that she finds wanting Anjali. Well do it herself in the eighteen. Hundreds reports started appearing virgin births among chickens for those who need a basic farmyard husbandry primer poultry. Lay eggs regularly. Those the ones you eat but but you need a male generally speaking if you want baby poultry. Researchers started studying similar events in Turkey's finding that the turkeys were laying unfertilised sized eggs that still developed into live chicks in most documented instances of parthenogenesis. The offspring is female a half clone if the mother the Turkey pulse however were always male which was put down to a quirk of bird. Generics where male sex chromosomes are dominant SUNA. parthenogenesis strain of domestic turkeys was developed in which most males appeared normal and reproduced successfully scientifically speaking the Turkeys for regarded. More as a curiosity. Something that only happened in human impose conditions in the past few decades though more and more cases of virgin births breath have been reported in snakes lizards and fish including sharks just what we needed infinitely replicating sharks to the people who greenlight green light sci-fi original movies know about this in two thousand one one of three captive adult female bonnet head. Sharks gave birth to the healthy female pup. The sharks had been caught when they were not yet breeding age yet. One of them in the tank had clearly given birth. Genetic tests confirmed that no males had been involved and since then the phenomenon has been discovered in four other shark species in two thousand. Six scientists reported that two different Komodo Motoko trangens giant carnivorous lizards with toxic. Spit had also had virgin births. UK Zoos scientists have also documented different snake species including boas and pythons giving birth in captivity in the absence of males. This left to questions. How and why one possible answer may lie with the whip tail Lizard? Certain subspecies are entirely female. Males have been cut out completely from the reproductive to process each female produces asexually creating new generations of females creating such an exclusive. No Boys Allowed Club. has its benefits. It's if any of these lizards were left stranded. They could still pass on their genetic material. The ultimate goal of all animals if you had to wait around for a male to show up in your DNA might end with you. That's thought to be the reason for the Virgin Snake. Birth in Louisville the snakes name is Thelma by the way thelma lived lived in a climate controlled environment and had plenty of food optimal conditions to undertake Sola parenthood. There's a catch though a sexual reproduction is the ultimate form of inbreeding. There's no way to insert genetic diversity so animals that clone themselves leave their lineages vulnerable to disease mutation for for that reason after the Virgin Birth of the Komodo dragons. Scientists recommended that the dragons which are endangered not be kept in isolation they would need genetic diversity city to withstand a chance of long term success as a species. Some scientists believe that parthenogenesis may actually be an ancient form of vertebrate reproduction action the species. That do it. Well like pythons and sharks for example are also some of the oldest species more recently evolved species it's like cobras fare less well producing only one or two babies which often died. Unfortunately parthenogenesis isn't something that we can tell by looking at the fossil record it's also pert near impossible for us to truly know how many wild species reproduce on their own. There are too many fish in the sea to be able to tell if they're forgiving virgin birth and many shark species are endangered to the point that it would be unethical to catch them for study. So why do animals reproduce alone when a sexual sexual reproduction has so. Many downsides and males are plentiful genetic diversity isn't the end all and be all baby sharks into virgin. Mothers are less genetically diverse than those born to two parents but they also appear to be justice healthy having been quote purged of all deleterious recessive genes. According to one researcher females females may also choose to reproduce alone because the act of sexual reproduction finding a partner having partners fight over you. The act of meeting itself uses up a lot lot of resources or perhaps something other than evolution is at work perhaps virgin birth sir triggered by an outside factor. Hormone or a hormonal imbalance once or even a pathogen like a virus or parasite species of Wasp for instance. That starts reproducing asexually after it's been infected with a particular bacteria and that's where we run out of ideas at least for today and now back no pun intended to the Suriname toad. If you have triple phobia an aversion to clusters of small homes. Thank you for listening. And I'll see you next week. For the rest of US Suriname toad reproduction. Election goes like this. The female toad laser eggs and the male toad fertilizes the eggs and then scoops them up onto the female's back. Her skin then grows Over the eggs protecting them until they hatch imagine a honeycomb but each cell rather than containing delicious delicious honey holds a tiny black tadpole or frog after a few weeks the little baby toads squirm and burst out of the holes of her skin. Ready to swim and look for food. The female then sheds her skin is ready to mate. Again it's weird and gross and amazing remember.

"That spirit of giving not lost on fellow always you alarms like Mike Darwin who grew up in total played football and as you and is now a tied in with the Dallas Cowboys you know the guy from the day I saw a photo of the state I was thankful for what he did. the impact that he had a localizado never be forgotten obviously our city is named after him and you know just the contribution that he did we wouldn't be where we are without him there stuff they from the posts out there but you know he he definitely losses will be forgotten George Boscobel is owner Jerry Jones was emotional and speaking of pictures one of his long time trials. personal friend and he was inspirational a man of sports. his love for competing frankly was on match so much of the things that he accomplished. or not about the dollar but more about the competitiveness in the game that he put that he was involved in figures donations that lex generated the most headlines with former as your deputy athletic director Dave Martin said Pickens did way more than just that both tickets will be really really missed the whole pagans will never be forgotten could be surprised how many schools big universities big ten other big twelve schools and things have come here on campus just to go through and see our facilities just a great fan I'm he was there all the time and you could always talk to him the cowboys will wear a special helmet sticker in honor of tickets for the rest of the season including Saturday's game at Tulsa and kick off on that two thirty on ESPN two and on our sister station ninety six one K. X. Y. pregame at twelve thirty with Dave John and Robert the Oklahoma Sooners with a much longer road trip this weekend they play out to southern California tomorrow for Saturday's game against UCLA but like in Riley says the trip will be like many others with one key difference the only thing that's different I would say then you know Lubbock Dallas in those is is just the time difference you know and and we all said to comedy that you know going east and point my course Virginian those guys too so the the time difference when you're not going out there for a bowl game when when the time difference for that matter you have plenty of time in between the game that is probably the biggest adjustment won the water come for Riley also says he's been fairly pleased with a new defensive schemes of Alex ranch and his team's ability to make tackles in space which was a big problem last year there's been a few plays each game that that that showed up and you know as the competition continues to get better better start with this week we're gonna hafta we're gonna have to clean that up and do do better there so but in or plan once you guys are gathered in experience quickly but again the communication and the way we've covered in all early on with the system has been a big positive shooters in Berlin's kick off at seven PM Saturday. on fox and during a week in which former thunder star Kevin Durant trashed Oklahoma City and other places people and things in a Wall Street journal magazine article Russell Westbrook gave okay see a shot out all the tonight show with Jimmy Fallon yeah and then it's got a different hearing you say welcome started work on Houston Rockets is kind of weird for me for the first time but you know this is exciting I'm I'm happy I'm so thankful for all the people in Oklahoma City in and just kind of a new journey so now the use is great and I think it's a good good food over there this is true really a good it's a new thing at hot it really is hot and humid rush returns Oklahoma City with as you deem on January ninth should be a very special night at the peak of March morning already ready to use radio one thousand Katie okay.
