Biodiversity implies it isn't cultural.

Adoption studies also don't suggest that. Ashkenazi Jews seem to actually have a different brain model.

Different brain model?

Yes, a genetically different brain model.

Brain model doesn't seem to be a common term. The linked paper uses the word model several times but not in a way that matches how used it.
