Alright, Vitamin D accounts well for the races of humanity, the Caucasian, African and Occidental, the white, black and yellow races. For if you look at geography and the intensity of sunlight, and the need for vitamin D, that white is cold northern latitudes, black for hot near the equator and yellow for in between latitudes.
So the evolutionary pressure to have Vitamin D uptake to ward off disease and to have proper fit health would be a pressure to have white skin in Europe, black skin in Africa and yellow skin in Asia. The use of clothing for warmth is superior to hair for warmth and so the skin had to become white to gain enough sunlight and yellow to gain enough sunlight. So Vitamin D caused a color change of skin and a reduction in body hair.
Now there is another trait of Occidental of slanted eyes, but I researched that and slanted eyes appears in many African tribes and so I do not see it related to vitamin D, nor hair reduction nor skin color.
Now the origin of races via vitamin D should tell us something about whether Tuscan Man created the Occidental race or whether the African homo sapiens created the Occidental race?
Maybe, since the Occidental is closer in genetics to the Tuscan man, that Tuscan man is the origin.
Now I need to know if the American Indians races are closer to that of Occidental or closer to that of European? Because here we maybe able to tell which land bridge was crossed, the Pacific or Atlantic?
