"God of the Gaps" would be assuming that the genetic differences between ethnicities MUST include genes that
1.) Significantly impact the intelligence gap
2.) Are causative, and not associative, like melanin or hair shape.

>We studied the within-family relationship between brain volume and intelligence in the much larger sample provided by the Human Connectome Project and found a highly significant correlation (disattenuated ρ = 0.18, p < .001) .
This is not a comparison between different groups, certainly not ethnic groups. It is a comparison between people who share the exact same environment. This tells you nothing about how much genetics impact intelligence, only that in the absence of different environments, they correlate. And again, things can correlate without being causal.

In fact it goes on to say
>Using bivariate LD Score regression, we found a genetic correlation between intracranial volume (ICV) and years of education of 0.41
How long you spent in school has as much association on your intracranial volume as does your genetics.

This doesn't go over how these vary between ethnic groups, it just locates some genes that are associated with brain structure (which itself is not just "big brain = smarter"). Again, "ethnic groups are different genetically" doesn't mean "ethnic groups are different in the ways I want them to be different." Why haven't you brought up the massive genetic gap between us and the flying fish people?
