white female eggs have informed crossover during gradient ascent, the galaxybrains still havnt figured out how this is possible. Somehow the process that splices the DNA seems have foreknowledge of which side is going to perform better, and simply uses the best one, maybe there is some kind of intra-cellular tournement, maybe there are genetic markers and riders in the semen and emitted from the body which posts metadata about performance of every subsystem and keeps tallies of upvotes and downvotes in the existence of molecular structures which biologicsts still don't know the reason for their existence. Or maybe it's the process of calculus the female egg uses when reaching back into the carousel of "what worked before" to pick what will work best with a new thing now.

Regardless of the engineering explanation the white women seem to be evolving faster than the other racces and if you are able to keep that going for a few thousand years, then the human species will separate into mules, donkeys horses, race horses, and supermen.

The Youdi jelly like slime goblins are unhappy about having leaned into intelligence from mating within the 4th cousin group, so many thousands of years ago for 3000 years, creating their textbook ugliness.

The teachers have to be taught early and often to stifle this truth, that there is extreme variation in the human form. Even more than there are in Dogs, at least in terms of brain architecture.
