The history of J2-M67.

 I decided to dedicate about J2-M67 a special thread.

M67 is the most popular type of J2 among Armenians so lets understand it's origin.

M67 is 12.000 year old and has three different subclades each of them has quite different distribution.

1/ Z467 is mostly absent from Caucasus. It is not frequent among Armenians. It was found in Bronze Age Anatolia in possible Hittite period. Autosomaly shifted to East. It was also found in Italian Neolithic which is very surprising because in the rest of Europe it was absent. This means different origin of Cardial ware Italian Neolithic. 

2/ Z500 , M92 This is the most frequent type of M67 among Armenians. It is rare/not frequent among Caucasians. Except in Pontic region and parts of SW Georgia. We don't have much aDNA with M92 but judging it's structure and ages I am expecting to be a Kur-Araxian marker. A type of marker that moved mostly to West South West and not toward Caucasus.

3/ CTS900 Is found mostly among Caucasian people. Reaching the highest levels in the world among Nakh people. This peak is result of young founder effect related to the breakup of proto Nakh community. It was found in Eneolithic Meshoko Darkveti culture. Also in Maykop which succeded him. It migrated there from South which is confirmed by their autosomes. It was also found in LBA Hungary. Most probably it reached there via Steppe.

Conclusion. The M67 homeland was in historic Armenia. More precisely in it's Western / North Western part. Z467 migrated to West. CTS900 migrated to North, the M92 expanded in BA most probably with KA.
