While there are minor differences in verbal and spatial ability between the race

While there are minor differences in verbal and spatial ability between the races and subraces at all levels, which appears to be due to degree of neotonic selection, and degree of selection for sexual dimorphism (in other words, very minor), the principle differences between the races and subraces are the scale of the underclasses, where underclasses are determined by IQ, Neoteny, Dimorphism, Symmetry (lower error).

In other words, the europeans and east asians were under greater selection pressure for cooperation in harsh agrarian cycles, whereas the warmer climes were under greater selection pressure for early maturity against disease gradients, food availability gradients, and competitor gradients.

So in that sense while it is true that europeans and east asians are more ‘advanced’ genetically no group is prohibited from achieving the very same rate of genetic development in just a few generations under soft eugneics (reduction of reproduction in the underclasses).

This means basically that we have been reversing evolution for over a century and a half.
