"For haplogroup R1b, we identified a previously unstudied “eastern” branch, R1b-GG400, found in East Europeans and West Asians and forming a brother clade to the “western” branch R1b-L51 found in West Europeans. The ancient samples from the Yamnaya archaeological culture are located on this eastern branch, showing that the paternal descendants of the Yamnaya population – in contrast to the published autosomal findings - still live in the Pontic steppe and were not an important source of paternal lineages in present-day West Europeans."

Im slightly confused what they mean. "Eastern' branches which are xL51, and/ or not found in western Europe have been known for a long time.
What are they referring to ? Surely not one which encapsulates all EE/ WA R1b, because some is within M269, some is pre-M269.

So, if I understand correctly, now we have three brother clades under L23? I.e. L51, Z2103 and GG400?

No, smal contacted one of the authors and it is just Z2103, not a new branch.

Thanks for information... so much ado about nothing...

There is "much ado" regarding the upcoming Balanovsky paper. The distribution maps should be very interesting.


The last – but not the least – step included screening branch-defining SNPs in the entire Biobank of indigenous North Eurasian populations (led by prof. Elena Balanovska), which includes 26,000 samples from 260 populations. This screening resulted in frequency distribution maps of 29 branches of haplogroups R1b and C, thus increasing the phylogenetic resolution by an order of magnitude compared to the two initial haplogroups.
