Three Y DNA are published from Berkaber (~2500bc) All are J1-Z1842 which was also found in previous works in Dagestan. Another J1-Z1842 was found in MBA Hasanlu (2000bc). And finally, we have another Z1842 from Arslan Tepe EBA shifted to east which confirms that Z1842 was an important Kur-Araxian Y DNA. The age of this branch is consistent with Kur-Araxian expansion.
Genome wide Kur-Araxians derive the bulk of their ancestry from preceding Neolithic and Chalcolithic periods of RoA/South Caucasus. They have also an extra CHG ancestry ~19%.
The most interesting finding is that Aknashen type of Neolithic farmers is important for Kura-Araxes (KA). Except those KA sites that are situated in Shirak province (Karnut, Kaps). Areni ancestry is also well represented in KA. It must be noted that there were archeologic claims of very old KA pottery in Areni. This was so unexpected that Sagona expressed doubts about the validity of the age. But maybe there was some rational in it.
Anyway proto-Kur-Araxian homeland might be in a place where extra CHG will meet the Areni and the archaic Aknashen type. This shouldn't be a place far from the territory of RoA. Or quite possibly in it.
PS. Aknashen is a new Neolithic DNA from Armenia. It is different from Azerbaijan and Masis Blur Neolithic samples because it has some extra CHG/Iran_N ancestry. An odd combination most probably representing an older forager ancestry.
His Y DNA is J2-PF5197.
An Y DNA linked with Iranian plateau. Chances are quite high that J1-Z1842 and its upstream Z1828 are also related to this Aknashen type.
