@Amun @Grant what do y’all know about them?

The setting: Europe, about 7,500 years ago.

"Agriculture was sweeping in from the Near East, bringing early farmers into contact with hunter-gatherers who had already been living in Europe for tens of thousands of years.

Genetic and archaeological research in the last 10 years has revealed that almost all present-day Europeans descend from the mixing of these two ancient populations. But it turns out that’s not the full story.

Researchers at Harvard Medical School and the University of Tübingen in Germany have now documented a genetic contribution from a third ancestor: Ancient North Eurasians. This group appears to have contributed DNA to present-day Europeans as well as to the people who travelled across the Bering Strait into the Americas more than 15,000 years ago.

“Prior to this paper, the models we had for European ancestry were two-way mixtures. We show that there are three groups,” said David Reich, professor of genetics at HMS and co-senior author of the study.

“This also explains the recently discovered genetic connection between Europeans and Native Americans,” Reich added. “The same Ancient North Eurasian group contributed to both of them.”

The research team also discovered that ancient Near Eastern farmers and their European descendants can trace much of their ancestry to a previously unknown, even older lineage called the Basal Eurasians."

https://en.wikipedia.org/wiki/Haplogroup_DE

"The YAP insertion was discovered by scientists led by Michael Hammer of the University of Arizona.[12] Between 1997 and 1998 Hammer published three articles relating to the origins of haplogroup DE.[13][14][15] These articles state that YAP insertion occurred in Asia. As recently as 2007, some studies such as Chandrasekar et al. 2007, cite the publications by Hammer when arguing for an Asian origin of the YAP insertion.[8]

The scenarios outlined by Hammer include an out of Africa migration over 100,000 years ago, the YAP+ insertion on an Asian Y-chromosome 55,000 years ago and a back migration of YAP+ from Asia to Africa 31,000 years ago by its subclade haplogroup E.[15] This analysis was based on the fact that older African lineages, such as haplogroups A and B, were YAP negative whereas the younger lineage, haplogroup Ewas YAP positive. Haplogroup D, which is YAP positive, was clearly an Asian lineage, being found only in East Asia with high frequencies in Andaman Islands, Japan and Tibet. Because the mutations that define haplogroup E were observed to be in the ancestral state in haplogroup D, and haplogroup D at 55kya, was considerably older than haplogroup E at 31kya, Hammer concluded that haplogroup E was a subclade of haplogroup D.[15]"

Anyone of y’all got any info on them? Apparently the natufians were heavily mixed with these people

Most likely an early Out of Africa group that remained isolated from the main groups of OoA. They did not mix Neanderthals like other Eurasians. Likely lived around the Persian Gulf as fishermen/hunter-gatherers and went extinct when they admixed with UHG/WHG Levantines belonging to the main group of OoA.

The secondary thesis is that they were basal E & L3 North Africans, but this is likely dubious.

So they were Africans that migrated to the Middle East and stayed isolated there forming their own genotype? What did they look like? Since they had no Neanderthal or denisovan admixture I’m guessing african? Possibly khoisan like?
