Sounds like evolution to me. Does this mean that white people are more evolved than all the other races, or are we all just mutants?
I'll take mutants for $1000, Alex...
We're mutants, but so are brown skinned people, and blacks as well. For instance blacks have a gene (not all of them of course) which makes them more resistant to malaria, but they pay for it by being more likely to have sickle cell anemia. Similarly our light skin allows us to produce more Vitamin D in the lower sunshine of higher latitudes, but leaves us more vulnerable to sunburn and skin cancers.
Mutation is what allows evolution to proceed. Most mutations are undesirable, but they also allow species adaptation to changed conditions.
Reminds me of a bit from an old That Was The Week That Was compilation. Among a set of parallel sound bites demonstrating that loonie extremists on opposite sides are more similar to each other than either of them is to normal people:
Ku Klux Klan Speaker: The white man is two hundred thousand years more evolved than the black man!
Black Radical Speaker: The black man was the first man!
