Actually, they are not. The racial categories were established before there was any knowledge of genetics and no genetic information was included in the categorization. What Rosenberg et al. demonstrated, was that there are various genetic markers that can be used to identify geographic origin, but that there is no overall similarity in genetic make-up within the smaller populations that come from adjacent geographic regions. This supports Cavalli-Sforza’s examinations of genetics that led to his conclusion that “race” is a false category in biology: Cavalli-Sforza, L. Luca; Menozzi, Paolo; & Piazza, Alberto (1994). “Scientific Failure of the Concept of Human Races,” in The History and Geography of Human Genes. Princeton, NJ: Princeton University Press.

I can’t pull up a full Science article from home, but from Rosenberg’s abstract:
“Within-population differences among individuals account for 93 to 95% of genetic variation; differences among major groups constitute only 3 to 5%. Nevertheless, without using prior information about the origins of individuals, we identified six main genetic clusters, five of which correspond to major geographic regions, and subclusters that often correspond to individual populations. General agreement of genetic and predefined populations suggests that self-reported ancestry can facilitate assessments of epidemiological risks but does not obviate the need to use genetic information in genetic association studies.”
To me, that sounds different from what you are saying. Not saying you’re wrong, as I’m out of my field here!
But, it sounds like they ARE identifying genetic markers, within geographic regions, that are predictive of epidemiological risks. Is it such a stretch to predict that there would be genetic markers predictive of height, speed or even ability to hit a baseball? Are you saying that these geographically close “subclusters” do not group together genetically?
They even seem to be saying that self reporting one’s race is in the absence of genetic data, while not perfect, indicative of genetic groups as evidenced by epidemiological risks.
Leaving completely aside the concept of “race” as in, I think that dude looks black and taking “race” to mean these genetic markers. I mean, you’re absolutely right when you say that these racial categories were determine long before we knew there was a thing called DNA. From that standpoint, of course those characterizations were silly.
But, now we do know, and we have technology that is remarkable (and, actually a heck of a lot better since 2002 when Rosenberg published!). So, are we simply disagreeing on what a “biological basis of race” means? I mean “race” to mean nothing to do with what someone appears to be.
My guess is that there would be some differences in “intelligence”, to the extent that this is (like race!) a meaningful term. But, I make no claims, as Watson did, that I have any idea which direction those differences would be and in whose favor because the confounding variables of other, non genetic factors, are too great to make any blanket claims.
And that, you with the face is why I feel like I’m not defending the guy. I think it’s perfectly acceptable to research something, but Watson seems to have preconceived notions based on his life experiences which influence how he wants the data to turn out. So, he isn’t racist because he believes there is a genetic component of intelligence that might link to genetic race, but because he has already decided what direction that would go without the evidence to back it up.
