As to the point of the discussion:
[QUOTE=smiling bandit]
I’ve mentioned it before and I will probably do so again, but there IS such a thing as race. It has nothing to do with intelligence or capability or moral worth, but the scientific concept does exist. Anthropologists are very uncomfortable with it, and tend to hide it these days, but it does exist and denotes certain extremely large human populations, all of which have interacted and interbred. There are only about four of them.
There is also such as thing as ethnicity, which is a much more complicated beast.
Now, I can’t imagine such as thing as a race traitor. or really even an ethnic traitor.

No. The Four (or Thre or Five–folks cannot even agree on that number much less who gets to be in which group), do not exist as a biological reality.
There are, indeed, populations of people who are more closely related, genetically, but there are far more than three to five of such groups. The lumping of large numbers of determinable populations into “races,” however, is meaningless. For example, most lumpers would put all the various African populations into the "black’ or “Negro” race, yet the Khoi-San are genetically more distant from the peoples of central Africa than the peoples of central Africa are from some Asians.
I do not like the phrase “races do not exist” because it makes a series of declarations with different meanings and different understandings among any group of speakers and listeners.
It is, perhaps, more accurate to note that the word race carries so much baggage that its (potentially) legitimate use as the term for “population” has been irredeemably compromised.
In the Decmber 20, 2002 issue of Science, (Vol 298), Noah A. Rosenberg, Jonathan K. Pritchard, James L. Weber, Howard M. Cann, Kenneth K. Kidd, Lev A. Zhivotovsky, and Marcus W. Feldman published a study, “Genetic Structure of Human Populations.” In that study, they determined that there were a number of neutral markers in human DNA that, when analyzed as groups of loci, could identify with relative certainty the geographical region in which a person’s ancestors lived. (There were six such regions, BTW, not four.) However, the clustering of such loci was required, because no specific marker could be found limirted to any of the four geographical regions. Two individuals from Asia or South America might be able to be identiied as such without sharing any of the loci in common. Each autosomal microsatellite locus could be found in every population. It was only by seeing which ones clustered (often differently) among different people that they could work back to the six geographic regions.
The point about anthropologists backing away from the use of “race” as a descriptor probably has some validity, but the anthropological community continued to discuss “race” well into the 1970s until Cavalli-Sforza began producing biological evidence that the identifications of “races” (i.e. lumping all people into three to five groups), had no biological basis.
