This actually doesn't prove anything. The IQ testing is performed using standardized tests, in which certain pattern always repeats. Furthermore, you cannot possibly measure one's intelligence using the score from the IQ test, because the intelligence itself is way more complicated, and possibly divided into several branches.
In addition, the title of this thread would imply that the differences are "largely genetic", but no genes(or even gene loci) were detected, that are responsible for the human intelligence.
Human brain is much more complex, to measure its intelligence by the means of primitive IQ testing.
I'd even compare that with a Neanderthal trying to run a nuclear power plant.
