You really make me laugh. Yes, there is only 4% difference between me and a chimp, but does this mean that an absolutely miniscule difference of less than a percent between me and a Ghanaian doesn't prove anything? Give me a break!
Yes across our species we have different looks and different builds, but so far as anything that matters goes, we're the same. Or do you believe that big nosed people or brunettes are different from others?
If anyone wants to read up on the science of race there's a chapter in the book 'Intelligence in Question'. I'd lend you my copy, but I don't want it coming back covered in jam.
