Chimps don't have different skin, hair and eye color. We're not as diverse as dogs, though. Does that mean we've undergone lots of harsh evolution in a short time? I really don't care if human DNA is 99.99999% the same. What's the point if we are clearly very different. I think humans are pretty diverse. Chimps don't have different skin, hair and eye color.
