The Genetic Time Machine: Neanderthals…

[Matt Osborne]

My DNA test says I am 8 percent Neanderthal, I shall require reparations and land statements from the following list of Eurasian nation-states

[Realist]

LOL.

[Matt Osborne]

You laugh at the oppression of my ancestors? Colonizer

[Realist]

I am less than two percent Neanderthal.

[Matt Osborne]

See you even brag about your sapienprivileges

[keBOBster]

great stuff as always Razib

Mr. Khan, thanks for an informative and to me interesting article.

- 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.

"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?

[A.Pozzi]

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.

[A.Pozzi]

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?

[Razib Khan]

for humans anagenesis is looking better and better every year...
