What crows teach us about death with Kaeli Swift

TED Talks Daily


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
