Polar Bear: What’s your best guess on the 1/3 African? Khoisan maybe?
The commenter is referring to the genesis of the Caucasoid race in the Caucasus 40-45,000 YBP which was formed by an input of 2/3 Ancient “Chinese” and 1/3 Ancient Africans as per Stanford anthropologist Cavalli-Sforza’s groundbreaking research.
Incidentally, this great man is now being attacked by antiracist morons because he had the temerity to suggest that such things as human races either exist or used to exist. This scientific fact is now banned by anti-science Cultural Left obscurantist “fundamentalists” who resemble the religious fundamentalists they hate more than they care to note.
The commenter is asking what the Ancient African component looked like, and then asks whether they looked like a Khoisanid type.
No one really knows the answer to this question because the Khoisan as a race are new. The Khoisan people go back 53,000 YBP, but before 10-15,000 YBP, they looked a lot different. But yes, those people were the ancestors of the Khoisanids.
Have you ever seen the reconstruction of the earliest Caucasian 35,000 YBP? He’s insanely ugly and he looks nothing like any type of modern Caucasoid. He doesn’t look like any modern race, but if anything, he looks somewhat Khoisanid. However, modern Khoisanids are rather attractive people, and this ancient Caucasian looks awful. I think when God was handing out looks, this guy thought God said books, and he said “I prefer horror.”
I haven’t seen any reconstructions of these ancient Africans, so no one quite knows what they might have looked like.
But only the Khoisan and the Pygmies remain of those ancient Africans. However, the ancestors of the Khoisan probably didn’t look Khoisan, and we don’t know what the ancestors of the Pygmies looked like because the jungle consumes and reduces everything to raw soil, including human bones.
And keep in mind that at the time we went out of Africa 70,000 YBP, there were 40 different groups in Africa, and they were all extremely different from one another. We don’t know what any of those people looked like. An ancient skull from South Africa 35,000 YBP looks “Caucasoid.”
But this is just yet another case of the parallel development that I discussed in this post in which “Caucasoid” is a frequent property of human skulls whether of the Caucasoid race or not simply because the phenotypes available to man are only a small subset of all possible phenotypes.
Hence, “Mongoloid,” “Caucasoid,” and “African” phenotypes pop up regularly outside of those groups. To give an example, many Australoids appear “African.” This includes Negritos, and other Melanesians. Some Africans such as the Khoisan appear “Asian.” And on and on. Therefore we can’t tell just by looking at a human which of the 3-4 large human races that they belong to.
Only two of those 40 groups present in Africa when we left are among those that left Africa, and at one point, those two groups out of Africa groups suffered a mass extinction event to where they were reduced to 1,500-2,000 people, possibly due to the Toba Volcano eruption in India 73,000 YBP.
What’s interesting is that there were already modern humans in India a the time of this eruption, and this is earlier than the usual 60,000 YBP date for humans leaving Africa. That there were people already in India before the Out of Africa date shows that some humans left Africa even before the given date.
This reduction of a large population to a very small number via mass death is known as a bottleneck, and it is known that we non-African humans definitely went through an evolutionary bottleneck. Other species can also go through bottlenecks in their evolutionary history.
These bottlenecks, while devastating in terms of mass death, are often good on an evolutionary basis in terms of fitness. Often only the fittest survive these events in other words, leaving a more robust and adaptive population after the bottleneck.
