Sort of related: I watched National Geographic a while ago, and they had this show called "The Genographic Project" or something like that. It was basically about finding out where the human race had its roots. Now, most people know that the first humans migrated from Africa and spread around the world some 500,000 (?) years ago, but some stayed on the African continent. Eventually, the people in the programme discovered that different members of a specific African tribe had the facial traits of different ethnicities, despite their dark skin tone (one person would have for example Asian-like eyes, while another one would have more European-like eyes).
Exciting, huh?
