Identifying specific genes and associated racial distribution is an informative direction. The racial admixture in American Hispanics made them an excellent choice for analysis.

Interesting that there is support for a negative effect for Native American ancestry. I had assumed the low test scores of Native Americans was due to impoverished lifestyle issues on the reservations. This means that higher average Asian IQs post-date population of the Americas from Asia and are relatively recent. Urban specialization and agriculture appeared in the Americas though perhaps not so pervasively. Was it demands/ benefits of those which spurred selection? Relative population density and latitude challenges? Something else? Curious.

Good article.

Native Americans genetically separated from East Asians over 20,000 years ago, and then went through a severe bottleneck while migrating to the Americas that greatly reduced their genetic diversity relative to East Asians

Now they have to use ancestry-ism as explanation for intelligence differences.

What would you say to someone if he claimed that you’re more related to a random white person than your half-African child?

If I flipped a coin 10 times and got 9 heads I would say there is something funny about the coin.

"If, on the other hand, the causes of the racial gaps are the same as the causes between individuals within races, then the same genes will be found..."

perhaps resulting in a double-whammy of inter-racial on top of intra-group differences; & maybe at last someone can sort out whether there's really any genetic difference between Hispanics & Latinos, or if that's just a nomenclature thing
