Blonde Hair's Secret History: What Science Tells Us

How did humans get blonde hair? Surprisingly, blonde hair evolved at least twice, once in Europe and once in the Solomon Islands of the Pacific, from completely different genes. In the Solomon Islands, up to 1 in 10 people are born with naturally blonde hair, and it has nothing to do with European ancestry. Scientists traced it to a single-letter change in the TYRP1 gene, a variant found only in Oceania. European blonde hair comes from a completely different genetic switch, linked to the KITLG gene. Same hair color, two separate origins, opposite ends of the planet. In this video, we explore the origin of blonde hair, the genetics behind hair color, what ancient DNA reveals about the first blonde humans, and why evolution sometimes reaches the same result twice. ⏱️ Chapters 00:00 Blonde hair in the Solomon Islands 00:00 The single letter of DNA 00:00 Where European blonde hair came from 00:00 The oldest known blonde gene in ancient DNA 00:00 Why did blonde hair evolve twice? 💬 If blonde hair evolved twice, what other human trait do you think did too?
