How Humans Lost Their Fur

The video explores the evolutionary history of fur, its functions, and the reasons behind human fur loss. It discusses how early hominins like Homo erectus adapted to their environment through bipedalism and increased sweating, which facilitated persistence hunting. The video also covers the role of skin adaptation to UV radiation and the development of sweat glands, highlighting how these changes contributed to human evolution and thermoregulation.
