Actually your supposition would be based on a classical view of natural selection, but the reality is that some traits may not have been evolved at all, but acquired from other groups of early humans. Modern studies have found that upwards of four percent of DNA in non African populations may in fact have come from populations such as the Neanderthals. A group that did share a common ancestor with modern humans, but had split off, and evolved separately for over a hundred thousand years.
The irony being that Caucasian skin may sweat more, because Neanderthals had stockier bodies, and thus needed to sweat more to regulate their body temperature. Obviously it wouldn't be necessary today, because Europeans have more skin area then Neanderthals. Yet it could have persisted in spite of environmental adaptation, because it isn't necessarily that prohibitive to survival. It isn't like Europe is bereft of plentiful water supplies.
Speaking to whether there are races of men. Well scientifically speaking the answer would seem to be yes if you agree with the current classification of Neanderthals being listed as a subspecies of Homo Sapiens. Which if the DNA evidence holds up wouldn't even be worthy of debate, because last I checked two different species cannot mate, and produce viable offspring. So if this all holds up then it is just a matter of deductive logic that the family tree outside of Africa is fundamentally different.
In that different populations outside of Africa may carry the genetic heritage of other populations more of one in particular, or none of another. So in a very real sense parts of us from different parts of the world could be up to a hundred thousand years removed from one another. While I agree with your sentiment which is as I see it a real argument against racism. I think the reality is far more humbling, and far more telling about humanity. The truth is that our ancestors don't seem to have given a fuck about who they would fuck. So why should any of us. It really doesn't seem to have hurt us at all.
