    Yes. But of course, it is possible that Chinese Neolithic N has no living descendants at all.

Of course, in the case of such a hypothesis, the source would be some predecessor of Hongshan culture (e.g. Xinglongwa culture) rather than Hongshan culture proper.
    Very strong evidence indeed. However, the Devils Gate admixture analysis shows that there was a migration from Siberia to East Asia and Amur and not the other way round.

The Baikal Neolithic specimens seem to have been more similar to the present-day non-Slavic indigenes of the vicinity of Lake Baikal than the Bronze Age Glazkovo specimens are similar to the present-day non-Slavic indigenes, but that does not necessarily mean that the Baikal Neolithic people have survived and reconquered their lost territory around Lake Baikal in subsequent generations; it is possible that people who just happen to have been genetically more similar to the Baikal Neolithic people than the Glazkovo people are similar to the Baikal Neolithic people have conquered the territory from the descendants of the Glazkovo people sometime between the Bronze Age and the present.
    Yes, you are right, maybe the modern descendants of yDNA N do not come from Hongshan and neither from Baikal but from Western Siberia.

    I think they mean 50000.

    "F23 showed Ne patterns similar to those of other out-of-Africa populations up to 50000 YBP"
    "Jomons experienced consistently small effective population size after 50000 YBP, with some increases after 25000 YBP"

    Another thing I noticed in the same figure, it dates the divergence between SSA and Eurasians all the way back 100,000 years ago, which is consistent with previous papers as well. So I think there's a good chance that intra-Eurasian pop structure could be significantly deeper than what is typically reported.

    Looks like we're getting another aDNA lab complex, alongside the ones in Jena, Max Planck and Boston. That would make the countries with aDNA capacities Denmark, Germany, the US and Japan, to be followed by China shortly.
    Eh, there is also Ireland(Dan Bradley's lab), Sweden(Mattias Jacobsson etc), Estonia(Mait Metspalu etc).
    The Max Planck group and the Harvard group are allied through common descent from Svante Paabo, and the two ended up in a situation through no fault of their own where they share a proprietary reagent which cannot be shared with outsiders. Its likely the upcoming Chinese lab, which descends through Reich and Paabo, would be under the same constraints, unless they develop their own pipelines like the Japanese have done. Hopefully the Japanese or the Chinese, if they develop and share an independent pipeline, could help to open up the field.
    If I remember correctly, Japanese guys consulted with Willerslev.

    But the earliest signs of paleolithic culture appear on Japan around 30 000 BCE, so does the study have genetic data on the Jomon before the arrival to Japan? Or are they simply speculating based on the genetic diversity of the population that arrived to Japan. 50000 years seems like an awful long time ago to have any population to exist that could be directly pinpointed as exclusively Proto-Jomon.

    There's a rumor going around that sampled Khazar Y-DNA is R1a and Q (with just one Q). Wouldn't be too surprising.

    I predicted R1a-M417 is the Y-DNA of the Turkic peoples some months ago. Good to see aDNA confirm another prediction I've made.

    Any specific Q subclade in those rumours?

    No, and no mention of R1a clade either although Z93 is what one would expect.

    Supposedly everything in the Moscow conference will be put on Youtube but no timetable was given on that either.

    Bad prediction.

    All of the R1a in Turkic groups is from Indo-Iranians and Slavs.
