The Real Reason Africans, Asians and Europeans Look Different

10,000 years ago, a man in England had dark skin and blue eyes. We know because scientists read the DNA from his skull. So when did Europeans turn pale? Why do Europeans and East Asians have light skin for completely different genetic reasons? And how can two Africans differ in DNA more than an African and a European? In this video, we follow the evidence from ancient DNA, genetics, and evolution to explain where human skin color, hair, noses, and facial features really came from, and why the "three boxes" most of us imagine don't match what the DNA shows. 👇 Before you watch: When do YOU think pale skin became common in Europe?
