El origen de todos los animales

❓ Do all animals share a common ancestor? ✅ Do humans share an ancestor with another animal? Do all living organisms have a common ancestor? From 98.4% with the chimpanzee to LUCA 4 billion years ago: the tree of common ancestry. In this video, we debunk the classic "we descended from monkeys" theory and set it straight: we didn't come from a modern-day monkey; we share common ancestors. We trace the lineage within primates, from the split with tailed apes 25–30 million years ago to our most recent common ancestor with the genus Pan around 7 million years ago, and explain why that 1.6% of DNA that differentiates us contains almost everything that makes us human. At this point, a famous yet controversial candidate appears: Sahelanthropus tchadensis. We also discuss what the most recent evidence suggests about how it moved and lived. Then we zoom in to answer the big question: whether all animals—and all life—share a common origin. From the mammalian tree (placentals, marsupials, and the extremely rare platypus), we jump to amniotes, amphibians, vertebrates, and finally, to the earliest, most primitive multicellular animals. We conclude our journey with LUCA, the last universal common ancestor, estimated to have lived around 4 billion years ago: what genetic clues have been found (including 355 protein groups) and why it fits with a world of hydrothermal vents, metals, and oxygen-free metabolism. And yet, after all this evolutionary journey, we still don't have a gene to prevent us from stubbing our pinky toe on a piece of furniture.
