>Those traits all involve a very small number of genes.
>Intelligence involves hundreds at least.
So how can anybody be confident that such intelligence-determining genes, numerous in number, are EXACTLY THE SAME across all population groups in the entire world? Or another possibility is that these population groups have different sets of intelligence genes, but yet they just HAPPEN to produce the EXACT SAME RESULT regarding mental capacity.

Neither of these explanations appears very plausible to me.

>I also have some doubts about the racialist theory of intelligence.
I don't see why that study would doubt the racialist theory of intelligence at all. It shows a small IQ difference correlating with a change in diet. But the differences in national average IQs, worldwide, is much larger than just a few points.
