Hahaha yeah so I've heard

Do you believe Christians were responsible for creating the literary context in which the (Paleo-)Arabic script and subsequently the Qurʾān emerged from? Something akin to what we see the influence of Christianity had on the Armenian, Cyrillic, and (less convincingly) the Geʿez abugida script?

read it from ehret. will get back to you on the cognates.

the story of a descending heavenly table also exists in a ge'ez homily attributed to a 6th century bishop but in relation to the nine tsadqan (saints) www.academia.edu/47608498/Bey...

there's limited genetic implications one can draw from linguistics presupposing linguistic clusters parallel genetic ones and that speakers have genetic continuity with predecessors of the same language family.

so linguistics only provides low resolution genetic info, especially archeogenetic info.

the west eurasian source for the naqada gebelein samples was best modelled as hotu iran, which has the highest percentage of basal eurasian ancestry yet recorded. modern egyptians are best modelled by neolithic levantine farmers than autochthonous north african basal eurasians found in naqadans.

oh you're referring to the unknown third intermediate, late intermediate, and byzantine samples. i agree with you, but it's just bizarre to me that upper and lower egyptians would continue to remain distinct in their basal eurasian ancestry after the middle kingdom period.

what is it about those samples there that suggest this component? that study has ancient egyptian samples from the predyn to the roman period

you're right. the west eurasian source for the naqada gebelein samples was best modelled as hotu iran, which has the highest percentage of basal eurasian ancestry yet recorded. and it's very likely that basal eurasians were autochthonous to north africa according to pagani.

there's no peer-reviewed publication yet, but there's an article from someone who had access to a naqada sample from gebelein. it's admittedly low resolution but this component peaks in the kadruka sample from kerma, as well as in modern-day nubians, copts, and bejas.

as far as im aware, there's no solid evidence of the language spoken in these early nubian cultures during the predyn period. evidence of a nilo-saharan language only really emerge from the meroitic period.

wouldn't it be likely that the middle/terminal a-group nubians from the lower nubia and the eastern desert, who had settlements as far deep into upper egypt as hierankopolis, were these cushitic speakers?
