"The methods discussed above for Neanderthals are entirely applicable to distinct modern lineages and can be used to explore systematic and consistent incompatibilities. To my knowledge, no such result has been found. In 2014 I specifically asked a postdoctoral fellow in David Reich’s laboratory if they had looked to see if the pattern with Neanderthal introgression could be seen more modestly in the African forager genomes that they had early access to through the Simons Foundation, and was told they had detected no such signature"
is there evidence with other admixed populations? (east africans, malagasy, south asians, laitn americans)? There are more admixed groups than african hunter gatherers.
- With thousands of human ancient DNA samples, scholars began to notice that there was a subtle pattern of decreased Neanderthal admixture over the last 50 thousand years
- More precisely, there has been selection against Neanderthal-origin DNA in our genomes
For sure at last 97% of this genes are brain related and a selection against inteligence, mostly spatial-IQ.
My DNA test says I am 8 percent Neanderthal, I shall require reparations and land statements from the following list of Eurasian nation-states
LOL.
You laugh at the oppression of my ancestors? Colonizer
I am less than two percent Neanderthal.
See you even brag about your sapienprivileges
great stuff as always Razib
Mr. Khan, thanks for an informative and to me interesting article.

"For sure at last 97% of this genes are brain related and a selection against inteligence, mostly spatial-IQ."
Where did this information come from?
Simple fact, reduction of brain size + bigger brain size in the neardenthals.
Bigger correlation between brain size and Spatial abilites compared to others brains areas.
Monkeys having better spatial memory than humans.
And the most important fact, most spatial abilities are only needed for survival in the nature.
Thats why spatial IQ decreased to the absolute minimum, brain size decreased and verbal IQ become untouched or even improved.
Justify "For sure at last [sic] 97%..."
I believe your scenario is entirely of tortuous logic.
Just joking, humans like to inflate numbers.
Anyways, no one know what exactly the function of genetics variants we losed throught time.
My scenario is better than the explanation of alot of people for reduction in cranial human size.
Question:is monogenesis true or rather is polygenesis?
for humans anagenesis is looking better and better every year...
