If we look around in a crowd in any great metropolis we’ll often notice, visually at least, great diversity amongst our species. Our facial features, height, weight, hair and eye color, skin color, bone structure, and style vary considerably. Yet, on a genetic level, there is surprisingly little diversity among humans.
Dr. Barry Starr is a geneticist-in-residence at The Tech Museum of Innovation in San Jose, California, and also works at Stanford. Dr. Starr says there’s more genetic diversity among chimpanzees of the same troop than of any two humans.
