    Bohemia: Dynamic changes in genomic and social structures in 3rd millennium BCE centr

    Dynamic changes in genomic and social structures in 3rd millennium BCE central Europe

    Future Data Location: https://www.ebi.ac.uk/ena/browser/view/PRJEB45006

    Europe’s prehistory oversaw dynamic and complex interactions of diverse societies, hitherto unexplored at detailed regional scales. Studying 271 human genomes dated ~4900-1600 BCE from the European heartland, Bohemia, we reveal unprecedented genetic changes and social processes. Major migrations preceded the arrival of “steppe” ancestry and at ~2800 BCE three genetically and culturally differentiated groups co-existed. Corded Ware appeared by 2900 BCE, were initially genetically diverse, did not derive all “steppe” ancestry from known Yamnaya, and assimilated females of diverse backgrounds. Both Corded Ware and Bell Beaker groups underwent dynamic changes, involving sharp reductions and complete replacements of Y-chromosomal diversity at ~2600 and ~2400 BCE, respectively, the latter accompanied by increased Neolithic-like ancestry. The Bronze Age saw new social organization emerge amid a ≥40% population turnover.

    GAC and Corded Ware seem like an easy two, but TRB would seem too far north. At 2800 BCE it would seem too early for Bell Beaker, but maybe they have some radiocarbon surprises. Any other groups they can be talking about?

    Baden culture and related groups from Pannonia made it to Moravia at that time, so a presence in Bohemias South East in particular could be an option. Could yield some E1b1b as well, probably.

    More likely to have plenty of R1b and even R1a. I'm sure some E-V13 as well.

    This page from Krause's book makes me think it's TRB, paper is also form Max Planck. Krause.png

    One of the others I suspect would be a Farmer rich population who was the source of females in the Lech Valley Beakers.

    I'm not sure there is any E1b1b and even less confident about E-V13. That's because E-V13 might have a more Eastern origin around Slovakia,South Eastern Poland, Northern Romania, in the area of the Northern Carparthians or close by.
    Its however possible because Baden is in part a heir of Lengyel and Lengyel did occupy this potential homeland zone and already showed some E1b1b. Unfortunately the resolution was rather bad if I remember correctly.
    We have new results from the sister group Sopot from further South and they were quite diverse, but dominated by G2 and I2. But earlier Lengyel-Sopot finds from further North had E1b1b too. I2 should pop up a lot, because it might have dominated both Baden and GAC in Bohemia as well.

    There is however a different option for E-V13, namely to come from Tripolye-Cucuteni, being assimilated by Corded Ware and becoming a minority element in the Epi-Corded horizon of the region. E1b1b was present TCC and it was probably in Nitra culture as well, if we interpreted it correctly.

    Which brings me to the least surprising conclusion that the local CW was most likely strongly R1a, just like the daughter group Nitra, which might have been more mixed on the female side and here and there some local male lineages made it too = path for E-V13. But more than 90 percent was R1a, which makes it likely for all CW groups of the region. If E-V13 was extremely rare but present in Nitra, it could also mean the V13 guys came from a neighbouring clan and there was just marriage exchange and trade between them. But then which neighbour could it be? Would bring us back to a Baden derived-related culture...

    I think all Bohemian Bell Beaker samples found to date that were resolvable were R1b-L2+. Interesting is sample DA111, dated to 836-780 calBC which is U152+ L2+ FGC4183+ and belongs to the Hallstatt-Bylany Culture. More interested in what the Corded Ware samples tell us than anything else.

    It will be all about the coverage, just like some highly interesting samples from Croatia and Italia suffered from the resolution and probabilities being to low. Like the Sopot related J carrier. I guess we all would have liked to know more.
    The Pannonian study Nitra R1a might be just as important by the way.
    We can observe, archaeologically and genetically a resurgance of R1a in Eastern Central Europe with Unetice. R1a was pushed back by BB before, but then there was a fusion of different elements, including R1a lineages from an Epi-Corded context. But from where exactly?!
    Could be from one group more than others and a position close to the Carpathian metallurgists would make sense. Which would connect them to E-V13 as well, which became dominant element in the Carpathian metallurgical centre latest in the LBA-EIA transition.

    That's why I think that Corded Ware R1a might have been pushed back too far, while some more Eastern groups, like related to Nitra, grew bigger and even some Proto-Slavic clades might have taken that path.
