Ancient DNA from the Green Sahara reveals ancestral North African lineage - Nature

Pastoralism spread through cultural diffusion into the Green Sahara, where an isolated, distinct North African ancestry persisted.

First ancient genomes from the Green Sahara deciphered

A new study reveals a long-isolated North African human lineage in the Central Sahara during the African humid period more than 7,000 years ago

While a previous study could not precisely ascribe the ‘sub-Saharan’ component in the Taforalt genome, we now identify this ancestry as a deep North African lineage, with higher proportions found in the Saharan Takarkori individuals. This refines the earlier model, which proposed a dual admixture of Natufian and broadly sub-Saharan African ancestries. Our updated model suggests that the Taforalt ancestry is composed of a 60% contribution from a Natufian-like Levantine population, with the remaining 40% derived from a Takarkori-like ancestral North African population. Notably, both the late Pleistocene Taforalt and the mid-Holocene Takarkori individuals demonstrate equally distant relationships with sub-Saharan African lineages.

Our results showed positive values for Takarkori, indicating that it is genetically closer to Zlatý kůň than to sub-Saharan Africans, including Mota, a 4,500-year-old genome from East Africa. Nevertheless, various African populations with substantial OoA admixture were still genetically closer to Zlatý kůň than to Takarkori

In the global PCAs they float right above them lol. But in the Africa specific PCAs they're equidistant from modern African clusters.

What did the ANA people look like, are they closer to West Eurasians or Sub-Saharans

Beat me to it, you muddifuka. Aight time to lube up and read.

As for the study, the models even in the supplementary were dissapointing. None of them had DZU+TKK --> IBM

Also qpADM >>> G25

Weren’t the Takarkori 1/3 IBM 1/3 Nilotic related & 1/3 west African related?

Ah I see, so the takarkori women managed to keep the original ana genetic profile intact despite being only 7k years old.

This reminds me of the Tarim mummies that managed to keep the ANE genetic profile intact despite being only 4k years old

I'm seeing a lot of wild takes about how this proved ancestral north african are "not african" and are closer to eurasians.

Lots of these guys are having a field day with this
