Let me emphasize what I said earlier: every expressed gene you have is shared with people in the Great Rift Valley.

(Well, unless you have something like hemophilia or Tay-Sachs disease, though even then it probably exists in those groups either as a recent mutation or a recessive; the majority of genetic disorders are universal - most are point mutations which can spring up spontaneously - and are associated with specific groups only because of inbreeding forcing them to expression.)

The same does not hold in reverse.

If some disaster had struck the region now composed of Kenya, Nigeria, Ethiopia, Rwanda, and Uganda in 1000 AD, killing everyone in that area, 50% of human genetic variation would have been lost.

Had such a disaster killed everyone outside of that region, not one expressible adaptive gene would have been lost. Many would be masked, due to recessiveness, but they would all be there.

Have you checked all 25,000?

Hmmm, that could probably mean that there is 25.000 types of people.
500 - Are extremly dumb, white
200 - Are extremly dumb, black
1 - Are extremly dumb, yellow
5000- Are dumb, white
2000- Are dumb, black
10- Are dumb, yellow
10000- Are average, white
4000- Are average, black
100-Are average, yellow
3000- Are smart, white
3200- Are smart, black
4000- Are smart, yellow
500-Are extremly smart, white
600-Are extremly smart, black
700-Are extermly smart, yellow
And so on. You get the point. Now there may be subcategories, on beauty, skeleton weight, etc.

Now some of them reproduced more than others and so changed the numbers....

Schol-R-LEA: Are you sure for the 1.000 AD? If it happened 2.500.000 BC then it may change the genes...

No, I don't.

Hmm, I think it's either I who am confused or you?

I'm not confused.

Now, by talking about this thread we basically achieve nothing.

Unless you have some Neanderthal or Denisovan DNA in you. The science of it is still being looked at (as the story keeps changing), but it looks likely that the Tibetans got their genetic ability to live at high altitude from the Denisovans, and there may be other differences between Africans and non-Africans relating to that kind of DNA difference. It's unlikely that it has any impact on intelligence though as the Africans almost certainly represent the more intelligent species of the ones that interbred and the rest of the world's people don't appear to be at any disadvantage - some useful or non-harmful genes from Neanderthals and Denisovans were retained and the rest were lost through natural selection.

I wasn't aware of that; most of what I had read recently implied that there was no conclusive DNA evidence for interbreeding between different hominins and H. sapiens. Still, as you say, it isn't really anything indicating a variance in intelligence.

Something I forgot to mention is that inbreeding could be the cause of lower intelligence in some peoples. https://fellowshipoftheminds.com/2015/0 ... of-incest/

Seriously? Quoting that website?

They've cited reliable resources and, as an insider, I can confirm our detestable custom of cousin marriage.
