That's bunk. Way too many non-genetic factors involved. Just as African-American men have a high rate of kidney disease, but the effect is not genetic, it's entirely due to lower socioeconomic status.

So controlling for SES there's no difference in rates of kidney disease? I hadn't heard that. Is the same true of hypertension?

I read that in an old paper but it appears to be wrong, since the APOL-1 gene is a risk factor with higher freq from African ancestry.

Are you starting to notice a pattern of Greg turning out to be right? Does that reduce your confidence in other areas where he claims something you think is wrong?

I think the evidence for the existence of different cognitive adaptations is weak, and that culture and environment are sufficient explanations for the data.

Is there evidence that culture is MORE important than adaptations? A reasonable person might be agnostic between explanations in the absence of evidence, rather than assuming it must be entirely one or the other.

So Occam's Razor points to culture alone. But I grant that brain adaptation *could* have happened. I just don't see clear evidence of brain differences between populations.

Brain volume is not equal between populations, and that's correlated with IQ.

That's a secret, and nobody knows how to measure volume.

You really want to go to the skull calipers ??

Is the word "caliper" a magical talisman in your mind that dismisses the plain and obvious argument? It's just a measuring tool and the findings of calipers are confirmed by every other measuring tool. This is like denying multiplication because it can be done on an abacus.

Elephants and whales have *huge* brains ....

And they're ( elephants and toothed whales) smarter than most animals. But their neurons are different, brain organization is different. I'm smarter than the average elephants and it's entirely possible that you are too.
