Por que os humanos são a única espécie que tem queixo?

For millions of years of evolution, dozens of human species walked the Earth. Neanderthals, Homo erectus, Homo habilis... none of them possessed a true chin like ours. In this video, we explore the main scientific hypotheses that attempt to explain why only Homo sapiens developed this peculiar characteristic. Did the chin arise as a simple byproduct of evolution? Or did it play a role in sexual selection and media? Throughout the video, we present the fossil evidence and the most accepted theories in paleoanthropology and evolutionary biology. 📚 Scientific Sources • Holton, N. E., Yokley, T.
