Well yeah; actually there is…
iiandyiiii’s “superficial characteristics” refer to appearance differences (among other genetically-driven superficial characteristics).
These appearance differences result from genes which arose in groups post the L3/M-N split (using mtDNA markers) around the point in time that humans left africa (say; 75 kya, give or take). What became various Eurasian populations developed new genes which gave those populations–on average–different appearances from african groups, and different from one another just the way groups inside of africa differ from one another in a clinal fashion.
Should africans and out-of-africans be two races? Should there be 10 races inside africa and 5 outside of it? Should there be a thousand races? No races?..
Who cares? Race is a social construct and one might even argue that it’s a linguistic construct. But…
IF we create groupings the way we do–by allowing self-assignment to a (crappily defined and softly-biologically-bounded) category of Race/Ethnicity, we end up with groups for which the average gene frequency differs, and differs consistently. We will always find an average difference for genes governing melanin if we measure a large enough self-identified group of “blacks” and “whites.” It isn’t a matter of “grouping genetically,” but rather the reverse. Group by self-identification, and average genetic differences emerge for the reason I described above: Humans who migrated out of africa had very limited backflow of their genes into african populations. Therefore new genes which arose in africa and new genes which arose post-africa largely remained within their geographically isolated descendant populations.
The reason the traditional “races” look different is that their average gene pool is different.
An egalitarian (one who believes all human groupings are about the same for all but “superficial characteristics”) relies on faith that evolution has driven genes for superficial things but has not driven genes for non-superficial characteristics.
Arguing that races don’t define well genetically completely misses the point. The change of only a single gene might make a tremendous difference for a given characteristic. So you could have one grouping with a huge amount of variation (a hundred “races,” say), and another grouping with almost no variation. If the second group has just one critical gene not available to the other hundred races, then the second group might be substantially advantaged for that characteristic.
The same grouping division derived from the “superficial characteristics” underpinning SIRE groups also divides human populations roughly at the point of exit from africa, and this separates average gene pools at that point in time. The whole reason SIRE blacks and whites look different–on average–is that they have–on average–different underlying gene pools driven by migration and evolution. It’s a matter of faith by egalitarians that the only genes affected have been “superficial” ones, because it’s a matter of fact that the average gene pools are different. So different that the average appearance is not even the same.
I do not agree that everyone who seeks to figure out if average gene pool differences among SIRE groups drive average outcome differences is a “racist” with some sort of evil or selfish intent.
For reasons discussed elsewhere in other threads, the problem is at the root of how to handle social policy and race-based AA (which I firmly support).
Bad science leads to bad social policy.
For this reason I am asking iiandyiiii if research into the topic is a priori “racist” by his definition.
