ANE is a grouping of genes present at some times and in some places, and surely shared long ago by a lot of tribes, between Siberia and South central Asia and Eastern Europe. Concerning the I-Ean concretion, surely recent enough, we cannot rely only on this element; and are all these populations rich today in ANE sharing the same elements of primitive ANE? I don't know. Maybe I'm not logical?
Davidski argues that the "ANE" like ancestry in CHG is not just shared ancestry but real ANE admixture. We know that WHG is connected to Haplogroup I predominantly.
So if the Samara EHG did not get their R* Haplogroups from their WHG side than they must have got it from their ANE ancestry, supportive for this hypothesis is the fact that we have found R* Haplogroup in a ANE individual from Siberia 20000 years ago.
The fact that there is more ANE in some South_Central Asian populations than Indo European ancestry itself only proves that pre Indo Europeans there must have been a very ANE like paleolithic popultion in South_Central Asia and likely on the Iranian Plateau prior to Indo Europeans. That brings me to the conclusion that there should also be R Haplogroups which predate the Indo European expansion.
Another thing that it proves to me is, that if the ANE in CHG is real admixture rather than shared ancestry, than we will most likely find R Haplogroups in some CHG samples. How else could the ANE have ended up in the CHG population? So if they claim the CHG population did not have any R Haplogroups among them than those guys are simply contradicting themselves. Either the ANE in CHG is real, than it must have come via ANE migration. Or are we going to argue that wild Herders from the Caucasus kidnapped ANE wives now? This whole Wive Kidnapping exchanging nonsense is getting ridiculous.
But if they claim the CHG were entirely J Haplogroup and did not have any Rs among them, than ANE in CHG can't be real admixture but is only shared ancestry, because Haplogroup J is the brotherclade of I (UHG-WHG) and only afterwards with K.
I tend to the first option. Simply out of the logic that populations very high in CHG have very basal and diverse kinds clades of R Haplogroups.
As I said in the past in my very first posts and it seems my theory has been confirmed with all this.
In the Near East we are dealing with two or maybe even three ancient groups. One is EF (Anatolian_Levant farmers). The other are Caucaus-Iranian Plateau herders, who were a mix of something similar to EF and an ANE like group and became "CHG".
EF on itself is a group that appeared after two more ancient populations (Basal Eurasian and Proto UHG_WHG) merged.
A third group might be a Arabian type farmer population around NorthEast Africa or Arabia that appeared during late Neolithic when EF groups absorbed some [10-15%) Sub Saharan DNA.
