You have to kill off a lot of ‘stupid’

You have to breed for neoteny (big heads and finer bodies).

You have to get enough of the IQ in the verbal spectrum by transfer of feminine traits to males, without transferring male traits to females, or feminizing males.

Then you need to kill off even more stupid.

Then you need to redistribute reproduction upward to those that you’ve produced.

You will get german/nordics (bigger/heavier), slavs (bigger/lighter), and Celts(smaller/lighter) out of this process in the west. In the Han, well, they just have one population that persisted in the heartland, rather than the Polish-Ukrainian population that kept exporting waves into the european plain.
