The problem is that your view is reactionary. You've decided that 'race does not exist' is a 'PC mindset' so you've concluded that RACE MUST BE A REAL, TOTALLY SCIENTIFIC IDEA WHICH IS SETTLED BUT HELD BACK BY THE PC BRIGADE.No that's Not true.
Even a child can tell race in humans or animals.
You have not addressed Any of My posts in this string despite me posting alot of Meat and debunking two of yours. Ergo, one Has to wonder if you Are interested in the TRUTH of the matter or just semantically critiquing Goshin.
ie, One doesn't have to be a geneticist to know Lions and Tigers are Cats but NOT the same/that there is some inherent (genetic) distinguishment.
Nor does one have to be an evolutionary Biologist to know a Pygmy/Bushmen/San couple can't be give birth to a Christie Brinkley or Ban Ki Moon.
(and it AIN'T just "melanin")
It's only a question of whether we're talking race/subspecie or species in the above cases.
Again Coyne:
"..The subject of human races, or even the idea that they exist, has become Taboo. And this Despite the Palpable morphological Differences between human groups — differences that MUST be based on Genetic Differences and Would, if seen in Other species, lead to their classification as either Races or Subspecies..." (the terms are pretty interchangeable in biology).
Which is nonsense. Yes, pick someone from Sweden, another person from Sweden, and someone from Korea and there will be less genotypical variations (which translate into phenotypical differences) between the two Swedes than between them and the Korean. This is understandable and expected - pick two brothers and then a stranger who lives down the road, and you'll see exactly the same thing.
But there are two problems with this, if you take the purely scientific approach.
1) Where to draw the line is far from well-defined. I share more DNA with (in order) my brother, my immediate family, people ancestral to the local area, people ancestral to my country, people everywhere, apes. What gets called 'family', 'locals', 'race', 'species' is not well defined. The reason that 'race' exists is not because some scientists have looked at DNA - it is because of sociological reasons. You are trying to use DNA to validate your views, but that's putting the cart before the horse. You are trying to make scientific decisions based on pre-existing social constructs; your confirmation bias is present.
This was mentioned in the very text you keep quoting:
"How many human races are there?
That’s pretty much unanswerable, because human variation is nested in groups, for their ancestry, which is based on evolutionary differences, is nested in groups. So, for example, one could delimit “Caucasians” as a race, but within that group there are genetically different and morphologically different subgroups, including Finns, southern Europeans, Bedouins, and the like. The number of human races delimited by biologists has ranged from 3 to over 30"

2) The idea of subspecies is based on geographical (or social) isolation. While that has happened to a certain extent (hence the phenotypical differences) there has been a vast amount of crossbreeding, population movement and mixture - especially for the last 300 years or so. For want of a better word, we are all mongrels; those who share all the characteristics of a type of a particular race are increasingly few and far between. Once you decide to delineate by geography, your version of 'race' is a gross oversimplification.
I did a quick google and discovered this interesting paper which argues for it's own regional version of races - termed 'tribes' by the paper. If nothing else, I recommend reading pages 19 and 20.
tl;dr: Yes, regional differences do occur - but 'race' is a vastly oversimplified generalisation rooted in sociology far more than in science.
