BY nature or geological or evolution or whatever.. why are whites white colored? you know what i mean. so white that we are pinkish redish because you can see our blood. I know africans are darker because of the enviornement. Africa must be quite hot. Did the whites stay out of the sun, and hide in the caves? I think RUssia was quite cold so that explains it. What about in europe?
