"one race is more intelligent than another" is broad, and can be very
misleading, but... yah.

Not "fundamentally" - it is a major factor. So is early nutrition in
individuals. It seems as if you'd like to paint it as purely genetic or purely
environmental and then pick holes on that basis. It doesn't make a lot of
sense to me that a study of Asian children, brought up in _very_ different
environments, cultural and otherwise, would lead to the identical variation in
non-verbal. It seems unlikely, to put it mildly.

Do you really believe that the brain is exempt from natural selection?
Consider also, when wondering how marginal cognitive gains could evolve so
quickly, that one of the most valuable adaptions a species could evolve is the
ability to adapt quickly.
