Why Did Naked Humans Wait Almost A Million Years to Invent Clothes?

Humans lost most of their body hair almost 1.2 million years ago. The earliest clothing we can actually date back to? Somewhere between 83,000 and 170,000 years ago — found not from a scrap of fabric, but from a parasite that can only survive inside clothing. This video traces how scientists pieced together a story with almost no physical evidence at all: the body louse's DNA clock, a pigmentation gene used to date when our ancestors went bare-skinned, 120,000-year-old bone tools from a cave on Morocco's Atlantic coast used for scraping hides, a 50,000-year-old bone needle from Siberia's Denisova Cave that changed everything about how clothing was made, and Ötzi the Iceman — found in 1991 wearing a bearskin cap, a coat stitched from goat and sheep leather, and shoes stuffed with grass for warmth. It ends with the stranger part: once everyone had clothes, clothes stopped being just about survival — and started becoming a language we still haven't stopped speaking.
