Yes, where was G2a2? Perhaps slightly further north at the intersection of the northern Levant and southeastern Anatolia? Is that the origin though or further east closer to the Iranian Neolithic given the "G" found there? (G2a1 is in the Iranian Neolithic and G1a in the Iranian Chalcolithic.)
I agree. I'm sure you've seen this by now:
", no 190 affinity of Natufians to sub-Saharan Africans is evident in our genome-wide analysis, as 191 present-day sub-Saharan Africans do not share more alleles with Natufians than with other 192 ancient Eurasians (Extended Data Table 1).
The idea of 194 Natufians as a vector for the movement of Basal Eurasian ancestry into the Near East is also 195 not supported by our data, as the Basal Eurasian ancestry in the Natufians (44±8%) is 196 consistent with stemming from the same population as that in the Neolithic and Mesolithic 197 populations of Iran, and is not greater than in those populations."
The latter is the point we made in our own speculations. Then you add in that they find no affinity in the Natufians to SSA populations. So, maybe those speculations of Dienekes' to the effect that there was an early back migration of "E" to Africa were correct?
So, as we also speculated, there was a refugia closer to the Persian Gulf? That or in North Africa?
While there was continuity from the Mesolithic to the Neolithic, there was no continuity from the Neolithic to the Chalcolithic. By that period at the latest, all these populations were mushed together, as we might have predicted from the archaeology.
"During subsequent millennia, the early farmer populations of the Near East expanded in all 253 directions and mixed, as we can only model populations of the Chalcolithic and subsequent 254 Bronze Age as having ancestry from two or more sources. The Chalcolithic people of western 255 Iran can be modelled as a mixture of the Neolithic people of western Iran, the Levant, and 256 Caucasus Hunter Gatherers (CHG), consistent with their position in the PCA (Fig. 1b).
Admixture from populations related to the Chalcolithic people of western Iran had a wide 258 impact, consistent with contributing ~44% of the ancestry of Levantine Bronze Age 259 populations in the south and ~33% of the ancestry of the Chalcolithic northwest Anatolians in 260 the west. Our analysis show that the ancient populations of the Chalcolithic Iran, Chalcolithic 261 Armenia, Bronze Age Armenia and Chalcolithic Anatolia were all composed of the same 262 ancestral components, albeit in slightly different proportions."
So, the Levant Neolithic people moved around, but at a certain point, there seems to have been a specific movement southwest from the northeast, so much so that this contributes 44% of the Levantine Bronze Age.
I wonder how close this population was to the ancient Hebrews?
no G2a2 found, none
is G2a2 exclusive to Anatolian & European neolithic?

I'm not sure Basal Eurasian originated in Africa though.
The reduced Neandertahl may be related to admixture with E-Z830 and unrelated to the Basal Eurasian.
