The average nucleotide diversity (pi) for the 50 segments is only 0.061% +/- 0.010% among Asians and 0.064% +/- 0.011% among Europeans but almost twice as high (0.115% +/- 0.016%) among Africans. The African diversity estimate is even higher than that between Africans and Eurasians (0.096% +/- 0.012%). From available data for noncoding autosomal regions (total length = 47,038 bp) and X-linked regions (47,421 bp), we estimated the pi-values for autosomal regions to be 0.105, 0.070, 0.069, and 0.097% for Africans, Asians, Europeans, and between Africans and Eurasians, and the corresponding values for X-linked regions to be 0.088, 0.042, 0.053, and 0.082%. Thus, Africans differ from one another slightly more than from Eurasians, and the genetic diversity in "Eurasians is largely a subset of that in Africans, supporting the out of Africa model of human evolution." Clearly, one must specify the geographic origins of the individuals sampled when studying pi or SNP density. [1]

- DuskStar 7y agoIs there more genetic diversity in wolves, or in individual breeds of domesticated dogs? I would assume wolves. Does that mean that there are no dog breeds? For that matter, you seem to be conceding the point that there are different groups of people similar to those commonly referred to as "races" that have discernibly different traits - in this case nucleotide diversity. In other words, I do not think that your paper does not support your assertion that races do not exist. (And also completely failed to address the "these specific traits are significant and associated with particular races" component of my argument)
- MiroF 7y agoThe other poster is speaking from the large consensus among biologists whereas you are speaking from/citing...? Should I just presume you to be correct on race unless proven wrong?

- DuskStar 7y agoWhat terms would you prefer to use to describe different clusters of phenotypes? Or do you deny the existence of different clusters of phenotypes in humans? It doesn't have to be "race", since that's a really loaded word. "Ancestry" and "heritage" seem to be more popular modern equivalents. But do we really use either of those differently than people 100 years ago would have used "race", or are we just powering down the euphemism treadmill? I really think the main problem in this comment chain is that we're using different definitions and talking past each other.
