I think the important take home message is that you can't control for all environmental factors so these kind of studies are meaningless. Genetic diversity is very low in the Human population and we only diverged from our original population in Eastern Africa 100kya at the most. Thousands of Human genomes have been sequenced and the small differences between geographical populations are related to digesting different food, resistance to local diseases etc. No evidence that intelligence has evolved differently or faster.
If you want to argue about science then you do have to come up with some actual evidence.

Nobody said they did and you still haven't got your head around
The scientific method says that you cant infer a genetic effect between two groups when you havent controlled for environmental factors.
But we do have data from thousands of genomes and if you want to argue about science then you really need to come up with evidence rather than racist wishful thinking or wandering into Darwinian fantasy land. There's evidence that some geographical populations have evolved to be resistant to local diseases or to digest some food better but none that show regional differences in intelligence.

Nothing in science is absolute but in general heterosis is beneficial and so is genetic variation. In the absence of evidence to the contrary that stands, unless you think your hand waving explanation is evidence?
This has nothing to do with what you called a priori convictions about equality, it has to with evidence. My opinion, based on the evidence, is that there just isn't enough variation between populations or enough time for something as complex as intelligence (or other behaviours) to have diverged to a measurable degree. All it will take to change my mind is evidence.

If you're looking for substantial evidence for a hereditarian view of racial differences in intelligence then you ought to consult Rushton & Jensen's "Thirty Years of Research on
Race Differences in Cognitive Ability" paper.
It looks at 10 categories of evidence:- the worldwide distribution of test scores
- g factor of mental ability
- heritability
- brain size and cognitive ability
- transracial adoption
- racial admixture
- regression
- related life-history traits,
- human origins research, and
- hypothesized environmental variables.
Some of these are essentially the same points I've made. The authors make a case for how the evidence points to some genetic component in BlackWhite differences in mean IQ.
Noose.

I think that's true for some individual offspring but for the population as a whole heterozygosity has increased. New alleles have been introduced to the population

EDIT: It also doesn't take into account something that we know now is very important to childhood development - pre natal environment.
You have a doctorate in a biological science and you are unaware that the brain develops with priority over the body? In the event of malnourishment, the brain is preferentially spared, while some part of the body is sacrificed, for instance rickets. Blacks are stereotyped as gifted athletes. They also have a fundamentally different developmental curve than other races. They learn to walk earlier. Their brain development plateaus earlier and degenerates earlier, consistent no matter the environment. There are similar male female differences, quantitative and qualitative. Are males and females gestating in unequal wombs?
Evolution predicts this seamlessly. Whatever the alternative theory is, (poverty, discrimination, ghetto culture, etc) it requires endless unique exceptions for every little observation. -

I got my undergraduate degree in 1996 when the first really important papers on epigenetics were coming out and it's this effect that I was referencing along with other critics of the work. Uterine environment affects epigenetics which even you must know means non genetic effects.
The rest of your post is just your usual rambling crap though I'd like to know exactly what you think 'evolution seamlessly predicts'.?

Where did I say race doesn't exist? I said -
This doesn't mean there aren't genetic differences between geographical populations, of course there are, they just don't line up with the obsolete classifications of race
. Sociologists and Human population geneticists can call those populations what they like I suppose, that's not really my point.
