What causes evolutionary changes? Most usually this would be adaptation to new habitat, which only the slightest use of your abstract capabilities should be able to appreciate of that kind of pressure. Perhaps a class in physical anthropology might help out with understanding the racial differentiation. We have several dispersion models from out of Africa based on some marvelous wide range studies in genetic marker samplings.

But you can't imagine what might pressure these gradual changes from all the fossil & genetic data we have? Subject to new environments & climates after these migrations & dispersion? Back to the earliest bipedalism & adaptaion to living on the plains? Epic fail, we expected no less, now go sit in the corner, maybe try spinning yarn & make yourself really useful.
