    OK. I think I found new ancient Polish genomes:

    http://www.ebi.ac.uk/ena/data/view/PRJNA354503

    DNA samples were isolated from the teeth of human skeletons dated from 100 AD to 1,200 AD

    will prof.David Reich disclose us something new on the 12 july 2017?

    Iron Gates sample Vlasa37, dated to 6767-6461 cal BC), is R1b1a2-V88/PF6279. In the Mathieson Balkan paper, a lot of the Iron Gates samples are R1b1a(xR1b1a1)... with R1b1a1 the the lineage that lead to almost all modern Western European lineages. The association of the Iron Gates hunter-gatherers with the much older R1b1a Villabruna sample looks stronger than ever IMO.

    Author: Zuzana Hofmanova

    Dissertation Abstract: Palaeogenomic data have illuminated several important periods of human past with surprising implications for our understanding of human evolution. One of the major changes in human prehistory was Neolithisation, the introduction of the farming lifestyle to human societies. Farming originated in the Fertile Crescent approximately 10,000 years BC and in Europe it was associated with a major population turnover. Ancient DNA from Anatolia, the presumed source area of the demic spread to Europe, and the Balkans, one of the first known contact zones between local hunter-gatherers and incoming farmers, was obtained from roughly contemporaneous human remains dated to ∼6 th mil- lennium BC. This new unprecedented dataset comprised of 86 full mitogenomes, five whole genomes (7.1–3.7x coverage) and 20 high coverage (7.6–93.8x) genomic samples. The Aegean Neolithic population, relatively homogeneous on both sides of the Aegean Sea, was positively proven to be a core zone for demic spread of farmers to Europe. The farmers were shown to migrate through the central Balkans and while the local sedentary hunter-gathers of Vlasac in the Danube Gorges seemed to be isolated from the farmers coming from the south, the individuals of the Aegean origin infiltrated the nearby hunter-gatherer community of Lepenski Vir. The intensity of infiltration increased over time and even though there was an impact of the Danubian hunter-gatherers on genetic variation of Neolithic central Europe, the Aegean ancestry dominated during the introduction of farming to the continent.

    Is that the same one as SC1, or are we talking about at least two R1b-V88s from the Iron Gates?

    So maybe R1b-V88 was the Mesolithic y-dna lineage there at the Iron Gates?

    Meanwhile, P297 was farther east.

    Possible, but with the diversity exhibited I would not count out P297's presence in the region too.

    I don't know about P297, but six of the Iron Gates hunter-gatherers are confirmed xR1b1a1a2, and now with this V88 sample, it makes seven.

    Except there is no evidence of it. Can't count it out, but one can't really count it in either.

    Sorry but what does the fact that 7 iron gates samples are xR1b1a1a2 imply? That V88 has modern descendants? I don't know what the x in front of R1b1a1a2 means? He absence?
