    The Neolithic Transition in the Baltic Was Not Driven by Admixture with Early Europea

    Wow!!

    Here:
    http://www.cell.com/current-biology/...822(16)31542-1

    Highlights
    •A degree of genetic continuity from the Mesolithic to the Neolithic in the Baltic
    •Steppe-related genetic influences found in the Baltic during the Neolithic
    •No Anatolian farmer-related genetic admixture in Neolithic Baltic samples
    •Steppe ancestry in Latvia at the time of the emergence of Balto-Slavic languages

    Further, the Y chromosomes of two of our Latvian Mesolithic samples were assigned to haplogroup R1b (the maximum-likelihood sub-haplogroup is R1b1b), which is the most common haplogroup found in modern Western Europeans [36].
    Great!

    Isn't that exactly as archaeologists thought it happened? Narva was always supposed to be continuity, as far as I recall. Like Ertebolla. Not to downplay importance of the paper, just good to see that DNA is not the only gauge in the past that works.

    The R1b in HG1 was fully WHG (See Supp Info, fig S4), which is the 2nd R1b in WHG.

    Narva and Ertebolle were pottery-making hunter-gatherer cultures descended from that which arrived in Samara, Russia by 7000 BC. We already have R1b1* from Sok River, Samara c. 5650-5555 BC. So no surprise. Exactly as expected really. At least by me. Quote from AJ:

    Around Lake Baikal in Siberia the favoured form of pot combined the pointed-base shape with an everted rim. The pots were mainly built up from clay coils, pinched together, and often left undecorated. This type of pottery reached the Samara region in the middle Volga River valley by 7000 BC... It was the first pottery in Europe. From there pottery of the same type had spread to the Baltic and Scandinavia by about 5500 BC, before any sign of contact with farming.

    Yet more evidence of R1b1b's provenance in Eastern Europe.

    The notion that R1b1b was introduced to Eastern Europe from West Asia just went from highly unlikely to near-impossible.

    Well, for me this came as a major surprise. After all those leaks from Mitnik's Baltic aDNA (remember I2a pure WHGs up until CW comes), this came as a lightning for me.
    Still have not read the paper... )

    We have to keep in mind that not only the Sok River sample is R1b1 but it is also in line towards R1b1a1a1. We don't know that that is the case for the Latvian samples ("the maximum-likelihood sub-haplogroup is R1b1b").

    No doubt.
    I would also go a bit further and say that we may not need to bring European R1b-M269 from the steppe in a post Neolithic time-frame.

    I don't think so, they had this to say about the samples

    In keeping with their geographical origins,they are in an intermediate position between Western Europeanhunter-gatherer samples (WHG; from Luxembourg, Hungary,Italy, France, and Switzerland) and Eastern European huntergatherersamples (EHG; from Russia).
