Ancestor of R1a men on GEDmatch

[Arhat]

Conventionally the Yamnaya are thought to have been the PIE culture which spread westwards.

P.S. Nice to see you back, brat! You are the real Aryan here

Interestingly this Sredny Stog guy can be modelled as mixture of Yamnaya and GAC but Yamnaya did not exist 6000 years ago so there was already a population similar to Yamnaya in the steppe prior to Yamnaya. Maybe this was Repin?

Yeah, Yamnaya was not the first Proto-Indo-European culture. Caucasus-related ancestry is from HGs in the North Caucasus region and already existed in Khvalynsk.

It already existed in a small quantity in a Karelian hunter-gatherer from ca. 5500 BC.

[Imperator Biff]

Seems to me like this I6561 Sredni stog II guy was a mix of Khvalynsk eneolithic and local EEF Cucuteni-Tripolye populations.

[Peterski]

He was from Sredny Stog Phase II:

https://en.m.wikipedia.org/wiki/Sredny_Stog_culture

"The expert Dmytro Telegin has divided the chronology of Sredny Stog into two distinct phases. Phase II (ca. 4000–3500 BC) used corded ware pottery which may have originated there, and stone battle-axes of the type later associated with expanding Indo-European cultures to the West. Most notably, it has perhaps the earliest evidence of horse domestication (in phase II), with finds suggestive of cheek-pieces (psalia)."

Yes Gedmatch Genesis is a bit different compared to regular Gedmatch:

whats the main difference?

[Norb]

is anyone here related to him on gedmatch?

how do I compare my results with his?

Seems to only work if I put in a lower threshold and minimum segment CM size

by lowering the SNPs and minimum cM, everyone matches with everyone else on gedmatch lol
