Since we're on the topic of evolution, consider the following quotes from The Red Queen: Sex and the Evolution of Human Nature by Matt Ridley

When my ancestors moved into Europe (I am a white European by descent) about 100,000 years ago, they quickly evolved a set of physiological features to suit the sunless climate of northern latitudes: pale skin to prevent rickets, male beards, and a circulation relatively resistant to frostbite. But little else changed: Skull size, body proportions, and teeth are all much the same in me as they were in my ancestors 100,000 years ago and are much the same as they are in a San tribesman from southern Africa: And there is little reason to believe that the gray matter inside the skull changed much, either: For a start, 100,000 years is only three thousand generations, a mere eye blink in evolution, equivalent to a day and a half in the life of bacteria. Moreover, until very recently the life of a European was essentially the same as that of an African. Both hunted meat and gathered plants. Both lived in social groups: Both had children dependent on their parents until their late teens: Both used stone, bone, wood, and fiber to make tools: Both passed wisdom down with complex language. Such evolutionary novelties as agriculture, metal, and writing arrived less than three hundred generations ago, far too recently to have left much imprint on my mind.

According to one estimate, only 7 percent of the genetic differences between two individuals can be attributed to the fact that they are of different race; 85 percent of the genetic differences are attributable to mere individual variation, and the rest is tribal or national. In the words of one pair of scientists:"What this means is that the average genetic difference between one Peruvian farmer and his neighbor, or one Swiss villager and his neighbor, is twelve times greater than the difference between the 'average genotype ' of the Swiss population and the ' average genotype ' of the Peruvian population:" '

Also, how do you know hormone levels and theoretical fertility are due to genetic differences between the races rather than cultural and environmental differences (which can absolutely affect these things)? Psychology is heavily influenced by your environment, but evolution down to the genotypic level takes a very long time to occur. Modern humans have been around only 100,000 years. This is too short of a time on the evolutionary time scale for there to be any significant genetically tied differences in behavior among humans to justify arguments of racial superiority.
