The differences in the races may be explainable by the amount of
testosterone. Whites have the least, orientals medium, and blacks the
most. (The other races will be somewhere among these.) My hypotheses
regarding human evolution suggest that the group with the greatest
amount of testosterone, should be the group that stayed in Africa.
Hence, blacks have the highest testosterone. So, the genomes need not
differ by much at all to produce different races. You may read my
short explanation of human evolution at on the web.
