I would tie my last post into the idea that certainly, there are different charecteristics between different races and ethnicities of people. We are all humans, don't get me wrong, but if you believe in elvelutionary theory, then you must believe that the variations in different people are present to improve the survival skills of that group in thier climate. Indeed, given some millions of years of development, we might eventually have not only different races, but different spiecies of humans, given enough genetic and enviromental variations, though with new technology, this seems unlikely.
However, do these differences account for personality differences in individuals? In nature important to personality. Studies on individuals would seem to indicate that nature is very important. Is it important on a race-by-race basis though? I'm still in the air about that.
The key to asking relevant questions is to avoid the large categories that are called races, and instead ask about smaller ethnic populations confined to a small region. In these cases there may be significant genetic variations compared to the larger human population. The small region requirement is important, because as groups spread out intermarraige with other populations will wash out some of the genetic uniqueness.
