Basal Eurasian discussion

[Desdonas]

Hey all what do you guys make of of the model from Lazaridis where ANA (Ancient North African) split from common Crown-Eurasian+Basal-Eurasian earlier. Does that make ANA a more basal than Basal Eurasian?

Can we safely assume that atleast Y-DNA E-M35 is related with ANA autosomal?! Looking at the skeleton remains from Paleolithic North Africa we can see that the so called Mechta-Afalou or Mechtoid people were quite robust in comparison with Natufians let's say, despite both bearing almost exclusively E-M35, with Iberomaurusians being more E-M78. I assume the high ANA autosomal is associated with more robust features, Paleolithic-Mesolithic Mechtoids were probably far more robust than Paleolithic Europeans, in terms of height they were at the same, with Mechtoids having taller individuals tendencies.

Can we talk with certainty there were ANA and Basal Eurasian population, or it's still to early to know for sure?

I think E is from back migration of basal type groups who lived in Sinai/NW hijaz and Egypt.
E has too low of a TMRCA,and especially it's subclades to be from an earlier split with Africans.

Taforalt could have extra layer of basal Ancestry for all we know.

On top of that ,natufians had more diverse and basal subclades of E M35 than taforalt which puts a hole in the whole theory.

East Africa is next to egypt/Sinai area,it makes sense we find more diverse clades of E there,but these could have been spread a basal type population from Egypt/Sinai,which later died out in its homeland(many examples like bacho kiro,ANE r1b,etc)

Yeah, but many of those Natufian samples were unresolved downstream, i guess even the Y-DNA CT were E-M35 of Natufian variant downstream.

Not holding a strong opinion but i think ANA should have been the original autosomal of Y-DNA E as a whole, with Bantuid Y-DNA E heavily admixing with more Basal human groups down Sahara like Pygmy, and those very distant Y-DNA A00 which were uproot even from Y-DNA A we saw from aDNA.

I also agree that ANA-related is the original autosomal of E (also D2/D0). Then, Southern and deep West African elements (A, A0, A00) merged with ANA-related. But I wonder whether ANA-related split from Crown-Basal relatively late. The chronology of C, F, and D1 points to a 65-64k split, and the three above all ended in Eurasia. Or we need more genome from East Africa, Sinai and Egypt to check whether pre-C, pre-F and pre-D1 exists. Last, the "Arabian Standstill" issue talked before may have some problems, but anyway the OoA allele selection points out a common bottleneck for the Crown-Basal meta branch.
