Those physical differences we make so much of are little more than cosmetic. For example, it was once taught that Asians developed their characteristic epicanthic fold as an adaptation to the bright sunlight and blowing sand their ancestors would have faced crossing the deserts into China. However, genetic analysis has shown that this trait developed after these people were in Asia. It could not have been an environmental adaptation. Instead, it's now thought that this mutation, as well as the characteristic straight, black hair, was selected for its aesthetic appeal. Potential mates who had these characteristics were prefered over those who did not possess them. It's not unreasonable to assume that other traits used to define "race", such as white or black skin, straight blond or dark kinky hair, were also originally selected for their aesthetic appeal. There's nothing PC about this.

We humans are 98% chimp and 33% daffodil in DNA mapping. The .01 to .2% difference in DNA mapping between human races and their subsets does account for more than strictly cosmetics. It accounts for marked physical appearance differences and bone structure and hormonal levels and hot/cold tolerance...etc.

Now you could surmise that some of these differences are cause by behavior or geography and you could be right but the DNA mapping differences doe exist nonetheless. Genes influence behavior which influences culture. Culture, behavior, and geography influence DNA over a period of time. The question like someone said before on a thread similar to this is "what came first?...the chicken or the egg"

I do not think that the DNA differences between races for whatever reasons they exist are purely cosmetic if cosmetic means inconsequential in your view.

Yes and no. Mainly no. If you'd like to hear more, ask.
