The Dzudzuana paper wasn't absolutely certain of flow direction
Also "Basal Eurasian ancestry is highest in the Near East, with estimates as high as 66% in Epipaleolithic Natufian individuals from the Levant " a similar proportion is found in Talforalt
It’s hard to be be 100 % sure.
Nevertheless, some affirmations from 2 studies (Dzudzuana HG’s & Anatolian HG’s)
Dzudzuana : 24500/17000 BC // AHG : 13700/13000 BCE // AAF : 8300/8200 BCE // PPNB : 7700/7600 & 7000/6800 BCE -
Dzudzu HG’s: 28/29 % Basal Eurasian BE > < Anatolian HG’s AHG : about 25 % Basal Eurasian -
Dzudzu closer to Anatolian Farmers then to Levant Farmers, than to CHG ! -
Dzudzu closer to WHG (Villabruna cluster) than to Natufians or North-West Africa
after Dzudzu appeared input of ANE in Caucasus and Iran, and of North-West Africa on Natufians
AHG : midway between WHG and a pop close to Natufians (so a bit closer to Natufians than is Dzudzu) – the authors think what they consider as the result of a crossing took place at least 5000 years before the beginning of agriculture (so : ? 15000 BC or sooner?)
Anatolian Aceramic Farmers AAF : ~90 % AHG + ~10 % Neolithic Iran-like
Anatolian Ceramic Farmers ACF : ~75 % AAF + ~25 % others, principally from Levant
ACF had more of Iranlike than AAF but Neolithic Anatolia (West?) as a mean has
less than AAF, what could suppose external later inputs -
Levant Farmers PPNB : ~78/82 % Natufians + 18,2 % AHG or 21,3 % AAF -
& :
Iron Gates HG’s (Balkans) : 63 % WHG + 26 % AHG + 11 % Natufian (
only 1,6 % Basal Eurasian BE in all) ;
&& : based on BE percentages (poor in Iron Gates), the authors thought WHG’s ancestors gave genes to people of Anatolia, rather than they took from them -
what may we try to resume from that ?
- BE was not among European HG’s, neither WHG nor EHG
- but BE is old enough around Anatolia, Near-East, Caucasus and surely farther towards South-East, and does not seem come recently from Northern Africa
- full defined Natufians cannot be ancestors to European HG’s, by lack of BE and lack of NWA among Euro HG’s, and they cannot be ancestors of Dzudzu by lack of NWA among Dzudzu -
- a possible osmosis (bilateral matings) could have occurred before agriculture between South-East Europe and Western Anatolia, when BE was not already high among Anatolians ; it remains the supposed 11 % of Natufians in Iron gates with a so low % of BE : drift : it needed enough time to reduce BE ?…
supposition of mine : a common metapopulation of HG’s occupied South-Eastern Europe, Anatolia and Caucasus before LGM, without any BE : maybe an « indivision » where Y-haplo’s IJ, I, J were dense before splitting their ways, Y-I replacing for the most previous European HG’s with Y-C ? Then (when ? Possibly soon enough too) came BE rich bearers from South Near-East or Red Sea surroundings, missing to colonize the more northern lands ? Before the coming of NWAfrica or even North Africa (with elements giving way to the Natufian mix and spreading some Y-E subclades ? -
All the way, the diverse European HG’s, whatever the roads they ran, did it long ago and cannot be considered as Natufians descendants – It’s rather Natufians who took from ‘Euro HG’, at a small scale -
other games of « go and return » of less
demic importance occurred in Near-East Anatolia Caucasus during Neolithic, Chalcolithic, Bronze and Iron, but they did not send any important novelty on genetic ground, IMO, only progressive osmosis ; only in Europe Neolithic changed things, and even there, more by proportions than by novelty.
IN SHORT, more than a direction to people moves in past, but not the same ones for all pop’s and not in the same time ! Let4s not confuse everything, OR WE MAY SAY WE ARE ALL OF US ARABS BECAUSE OUR DIVERSES CLOSELY RELATED ANCESTORS CROSSED ARABIA FROM AFRICA AT SOME STAGE OF EURASIAN HISTORY.
