>>19075516>>19075510The only primary physiologic difference among the races is the role of vitamin d, its production and absorption. We have basically 'woken up' in the middle of an evolutionary cycle where there were 5 basic races, but two were consumed into the Caucasoid in the stone age.
Blacks have lower serum vitamin d, which causes heart and metabolic issues in blacks primarily. Asians have moderately more than blacks but less than Whites, which shows that Asians are gradually becoming Caucasized, a process that started a few thousand years ago and will continue to completion within the next ten thousand years.
Essentially Caucasization is the replacement of genes, via recessive predation, that regulate the production and disposal of melanin within Vitamin A/D rich diets. Caucasoid humans require less consumption of vitamins A and D as they have physiological capabilities others do not. Whitening can be seen within 1-3 generations as the replacement of these genes causes D production, leading to exponential elimination of melanin waste product as, as it is disposed of, more D is produced.
