The genetic prehistory of the Greater Caucasus[preprint Harvard/Jena]

I just checked I6266 Klady 5200.0 Maykop J2a

He is positive for two SNPs at the J2a-Y11200 level, namely Y11861+ and Y18325+. Downstream he has no calls for any SNPs at the J-Z30677 level, and one negative SNP at the J-Y30811 level which is Y30811- itself. Also one negative SNP at the J-Y17946 level which is Z30682-

I also checked: I6268 Klady 5564.0 Maykop J2a1

He is positive for one SNP at the J2a-Y3020 lelel (Z7675+). Downstream he has no calls for any SNPs at the J-Y11200 level, but negative for two SNPs at J-Z30677 level (Z30700- Z30692-). But since he is negative for one SNP at J-CTS6804 level (Z7679-), he likely belongs to J-Y11200, like his contemporary I6266.

RK4001.A0101 Rasshevatskiy 4 Catacomb R-Z2108

Certainly adds some support that Catacomb derived from Yamnaya, and it should be no coincidence that nodes of Z2109 are most common in Europe, where as L584/L277 are more likely in the Middle East. Would be interesting to see where the other 3 R1b Catacomb samples fall.

Checked: I2056 Unakozovskaya 6477.5 Eneolithic Caucasus J2a

He is also in the J2a-Y11200 branch as he is positive for three SNPs at that level (Y11861+, Z30675+, Y18325+) with the rest being no calls. Downstream he is negative for two SNPs at J-Z30677 level (Z30690-, Z30687-) and the rest no calls.

Trojet thank you for all the hard work

Are you also going to check samples I2051, I2055, VEK008, MK5008, I1720 and I6270? By the looks of it I6270 and I2055 should also turn out to be J2a-Y11200.

You're welcome mate!

Any idea where sample I2051 Marchenkova Gora, D13 3260.0 Dolmen LBA J is precisely from, as I couldn't find this culture on the map. The sample is very low quality and reported as J by the authors, but I got one positive SNP at the J2 level

For the rest, might have to wait until tomorrow as I'm running out of time

After checking around 50 J2b-M102 SNPs, I just got one negative at that level (CTS1196-), so he should be some J2a.

I have no idea where he was from it would be interesting if he turns out to be some downstream M67, Z500 so far is the only branch of PF5119 that hasn’t appeared in ancient dna, so I wonder where it was hiding? It can also possibly belong to YP879 which is very common amongst Armenians.

Also something very interesting about these results makes me question the true TMRCA of Y11200 and Z1842 I don’t think its a coincidence that they were found but there upstreams and not common branches makes me wonder as these samples are young enough to belong J1-CTS1460 and J2a-Z30677, perhaps the TMRCA’s are off by 1000 years?

Some googling shows that it's from Gelendzhik District(you can just google Gelendzhik), on the Russian coast of Black Sea. There is no precise description of this particular dolmen, but here is the general article: https://en.wikipedia.org/wiki/Dolmens_of_North_Caucasus

This paper has turned up many interesting results, with hopefully some more surprises to come, we have the J2b-L283, the 3 J2a-Y11200 and J1-Z1842. The later 2 results might have further implications on the linguistic cultures of the area, as now some questions were answered but pose even more. We also have the 3 R1b’s tested with 2 V1636 and the Z2108 with more analysis coming up within the next couple of days.

Overall I would say pretty productive and relevant paper.

[ADW_1981]

I1635, the K-A sample from Armenia, also was R1b-V1636.

Yep, and these samples are about 4000 BC which would suggest that the Y chr in I1635 was an introgression from the north
