An important update on R1b-M269 in ancient Armenia in Etiuni period.
Large numbers of samples are now uploaded to Chinese theytree service and we have three cases of R1b-PF7562 in Bronze Age Armenia. From this three cases at last one was predicted as such by Lazaridis in the Southern Arc paper's supplements. The I14057 from Bardzryal site in Lori. The other two cases are from Karashamb in Kotayk and Keti in Shirak province. The one case is somewhat doubtful but whatever.
Whatever the case we can now say that both Z2103 and PF7562 are Yamna/Catacomb lineages. Both have the same TMRCA. An alternative origin of PF7563 becomes less realistic now.
Currently the only subbranch we miss is the Z2110 but given it's small number in modern Armenia ( although we have two person from this branch in this group ) we must be more patient.
If there was a some slim chance for Balkanian theory to resurge with PF7562 it's now game over for it. We can say that PF7562 in Armenia is from Etiuni.
