The L1a1-M27 found in Areni cave (Chalcolithic period 6200 ybp) is now uploaded in YFull. ( I1642 )
L1a1 is rare in modern Near East. It is popular in India but this is due to 4700 year old founder effect. In South Asia it is especially popular among Kalash people.
Only one Armenian from FTDNA is positive for M27. What is his exact relation to ancient Areni person is not yet clear but it is quite possible that he will be from the same subbranch.
Another L1a1-M27 potentially close to Areni lineage was found in ancient Central Asia (1700 ybp , Hunnic period ) . It seems L1a1 had a rare presence in BMAC. Most L found there are from L1a2 branch but not L1a1. After BMAC it made part of Saka community and reached even China.
In sum it seems that L1a1 ( 8300 year old lineage) expanded in Chalcolithic period from NW Iran and South Caucasus. In most likelihood it reached India during Harappan civilization period. Ancient DNA from Indus valley civilization is needed to prove this theory.
PS. We have five samples from Chalcolithic Areni cave. Three males. All L1a1. And two females.
