Why Did Ancient Humans Evolve Different Hair Textures?

Every human being alive today descends from one small population in Africa roughly 200,000 years ago — so why does human hair look so radically different across the world? In this video, we trace the real evolutionary story behind hair texture: from the heat-shielding coils that protected early human brains on the African savanna, to the EDAR gene mutation that reshaped hair across East Asia 30,000 years ago, to the surprising Neanderthal DNA still shaping European hair today. This isn't cosmetic trivia — it's a 200,000-year map of human migration, climate adaptation, and survival, written directly into your scalp.
