Its also found in dinka people indicating they carry north African/middle eastern ancestry, this north east African DNA is reflected in their haplogroups as Dinka people carry E-m215 and E m78 – Hassan 2008
https://imgur.com/a/jaacBlt This is also seen in the fact that the red component makes up a lot more of the ancestry in PN individuals than the analysis done by Prendergast et al shows, suggesting that there was north east African DNA hidden in Dinka peoples and that Cushitic ancestry is dominated by chalcolithic Israel/Neolithic Levant related DNA which is reflected in afro Asiatic speaking Horners exhibiting craniofacial patterns most similar to north Africans and middle easterners and haplogroups which show a clear dominance of northeast African lineages…
In this analysis dinka people show “non-African” related ancestry at k=2, but they have been found to have no neanderthal ancestry, indicating that they are in fact fully African I think this non-African ancestry represents a type of indigenous north east African population represented by the red ancestry that I previously mentioned which peaked in ancient Moroccans and Levantines, this population, genetically, had non-African affinities as seen at k=2 that would have carried E-m215 and E-m78, and may have carried M1a1 as this is carried by some Nilotic populations. Could this be a good representation of the kind ancestry we expect to see in ancient Egypt/Nubia? Could this be the common ancestry between, Ancient Egypt/Nubia, prehistoric middle easterners and modern/ancient MENA and the horn?
i could be completely wrong so i am ofc open to criticism

I think you're onto something here. It would make sense, given their location, for South Sudanese Nilotes like the Dinka to have been recipients of Northeast African ancestry related to ancient Egypto-Nubian populations. However, while I do recall reading that the Dinka have little to no Neanderthal ancestry like you say, I don't remember where I found that. Do you have a source for that to jog my memory?

You can use Carina Schlebusch 2019 paper on the Ballito bay sequenced samples. They're the latest to report Neanderthal estimates in African samples.
And yes the Dinka should definitely have "North African" ancestry. It's not non-African, but related to ancestors of Taforalt and early neolithic Moroccans.

Not doubting you or anything but how sure are you that this ancestry is related to ancient Egypto-Nubian populations?

Fu et al. [4] assumed that West and Central Africans (individuals from the Yoruba, Mbuti and Mende populations were grouped together as a single population) are outgroup to the East African Dinka population and present-day non-Africans. Then the Dinka represent a population with no archaic ancestry and Neanderthals and Denisovans ‘Archaic’ represent a population with complete archaic ancestry. https://www.cell.com/current-biology/pdfExtended/S0960-98221731195-8Posts: 161 | From: England | Registered: May 2020

i know you didnt direct this towards me but my opinion is that this could represent a population of mainly north east African origin, carriers of e-m215, e-m78, m1a1 and other lineages we expect to find/have found in Egypt and Nubia, such as haplogroup k1(found in abusir, Christian Sudan, Neolithic Syria, late Neolithic Morocco which are all populations we expect to cluster with early upper Egyptians/lower Nubians). This population also has non-African affinities at k=2 which is likely to be the case if Egypt and Nubia were dominated by OOA type ancestry
the fact that PN individuals and Afro Asiatic speaking Horners carried high amounts of this red component means this is possibly what comprised Cushitic ancestry to an extent(Dinka related as well), partly explaining the affinities between Nagadans, Badarians and Kermans with horn of Africans and modern north Africans who would carry this type of ancestry, this seems like the kind of common ancestry we would find in populations that cluster with Egypt/Nubia, groups such as Berbers/north Africans, horn of Africans, prehistoric middle easterners(Natufians, Neolithic levant) etc...
also, haplogroup k1 is found in Neolithic Moroccans, abusir and 18th dynasty Egyptians, Prettejohn Gully, horn of Africans and Berbers, the red component seems like a good fit for the kind of ancestry that all these groups contain and would have passed on this haplogroup, k1 is probably Eurasian in origin but the aforementioned north African DNA in Dinkas likely lacked this, as Dinkas have little to no neanderthal ancestry, so they mixed with this population very early or mixed with a subset which happened to be pure

where do you think the ancestors of taforalt/early moroccans came from? im assuming they were apart of a larger north african population? can you shed any light on this? thanks
