peoples opinions on this subject.

what is the biologicaly superior skin color and why do you say that.

personally i believe darker skin has a biological advantage. because light skin is designed for being in a cold climate with little sunlight and is ment to absorb as much vitamin D from sunlight as it can and burn easily. and with the world having more warm sunny climates than cold dark arctic climates dark skin that is meant to prevent or atleast lessen sun burns and not absorb as much D all at once is better. if a very fair skinned person lived in the carribian where there is constant sunlight and a warm to hot climate they without high spf sunblock over time could absorbe fatal amounts of D and get frequent burns increasing the risk of cancer. but a darker skinned person living in the arctic would have a difficult but not nearly as bad life. just being out in what sun they can be in and dressing warm would suffice.

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?
