clinal

Geneticists aren't saying there is no such thing as human variation across geographical distance; they're just saying that that variation is clinal.

Yet they don't have any strict genetic or pehnotypic border within, just clinal variation.

Populations differ in the patterning they have on the head, and while two subspecies have been distinguished on the basis of such differences, the variation actually appears to be clinal (McCarthy 1986).

At least some of the observed variation is real (and not just individual variation, or clinal) – but how much of it, and what does it mean for taxonomy and phylogeny?

To me they resemble the salukis of Arabia or most Iran, more than those of Central Asia, like mine, though all tazi- saluki variation seems clinal and influenced by climate and terrain, as in wild animals, rather than by faddish breeding.

Excluding these three groups, Rosenberg found a strong correlation between geographic distance and genetic distance, as the clinal theory would predict, but also found that the three main kinds of barriers -- oceans, the Sahara, and the Himalayas -- "adds an equivalent amount of genetic distance as traveling approximately 3,100 km on the same side of the barrier."

For population pairs from the same cluster, as geographic distance increases, genetic distance increases in a linear manner, consistent with a clinal population structure.

Rosenberg's new paper essentially quantifies my refutation last March of the pure clinal theory in VDARE.com.
