В текущей версии Y дерева 2026.04.12 уже выложили 2300 образцов Akbari и добавили возраста
Теперь самый древний R1b - 13176 до н.э.
We have currently processed the Y-DNA of about 2,300 of the roughly 5,500 male individuals in Akbari et al. 2026. As a reminder, some samples from past studies were re-sequenced as a part of this study and thus required reviewing once more.
All processed samples have been added to Discover, although a small number completed during the active Discover update may not yet be visible there. All 2,300 processed males have already been incorporated into the haplotree, so any newly identified novel branches or splits created by ancient samples processed this week can already be seen there and will appear on Discover in the next update.
Discover Update + Oldest Known R1b!
While we are still waiting on the full archaeological contexts for the Akbari et al. 2026 aDNA samples, Y-DNA Discover now shows their mean dates, which already gives us useful clues about their contexts and how close they may have lived to their branch’s MRCA.
One sample is particularly striking: I5410, with a mean date of 13,176 BCE. Our team has determined that he belongs to R-L761, which makes him the oldest known R1b sample to date. The paper lists him as coming from “East” West Eurasia, a region the authors define as including modern-day Romania, Moldova, Ukraine, Belarus, Russia, and Kazakhstan.
On the mtDNA side, he belongs to K1, making him the oldest known K1 individual and the second-oldest known K sample overall. Even more interestingly, he appears to represent a true K1* lineage, with no private variants of his own. In the next update, dates will be added to the paper’s 10,000 ancient samples for mtDNA.
