    The Genomic Formation of Human Populations in East Asia preprint

    This looks very interesting, with 191 samples total, though many are low quality.

    130 pass quality assessment:
    7 Jomon from Japan - 6 from near Tokyo, ~2000-1500 BC, and 1 from Hokkaido, ~3500-3200 BC.
    65 Neolithic to Iron Age samples from various sites in Mongolia (including Afanasievo, Chemurchek, and Slab Grave)
    20 from Primorsky Krai (extreme southeast Russia) - mostly Neolithic 5700-3600 BC, plus 1 Iron Age and 2 Early Medieval (Mohe)
    1 recent historical sample from Sakhalin (Ainu?)
    37 from Taiwan - 1 from about 1300 BC, the rest from ~AD 150-850.

    There are also 20 samples from Shaanxi, Central China, ~3400-2800 BC - all shotgun sequenced and of questionable quality, but still good enough to get some results.

    There's some J1 in EHG and Khvalynsk, so it was a minor lineage on the steppe since before Yamnaya/Afanasievo formed.

    Nothing amazing.

    Is the sample quality low overall or just the mtDNA coverage?

    Haven't had much time to look yet.

    Maybe the y call is good?

    The J1 call is 4.338 for the "average coverage on autosomal targets" column, where as the R-P311? guy is only 0.136. Are we looking at another case of those bad P311 calls like the ones on Central/South Asia. ie: that afghan sample?

    Judging by the coverage of the other samples 4.338 is pretty solid relatively speaking, so I assume that the J1 is fair game, the P311 quite possibly not.

    Yes, but not a minor lineage but the founder lineage who brought CHG_or proxies_Iran to the steppe and J1 has always been found in PIE archaeological remnants just like BMAC.

    The following blurb is quite fascinating from file "media-2". Indeed both Chemurchek males are R1b1a2a2, and it suggests close contact with Afanasievo, but also some parallels with collective burial megalithic Europe. Very bizarre since no R1b has been found in megalithic to date though. Some interesting discussion could come from this.



    Chemurchek (Qiemuerqieke) phenomenon: The Chemurchek phenomenon is named for the river 切木尔切克Qiemuerqieke in the Altai county of Xinjiang27,28. A complex of cultural features resembling those of contemporary peoples in Western Europe appeared in the slopes of Mongolian Altai (Northern Xinjiang and Western Mongolia) not later than 2700-2600 BCE. The architecture of the burial constructions, specifically megalithic chambers constructed from huge stone slabs with collective burials surrounded by multiple stone and soil cairns overlapping one another, the form and ornamentation of vessels, the stylistics of stone statue-menhirs with protruding facial contours and circular protruding eyes, paintings on slabs inside burial chambers (rhombs and chevrons inscribed into each other, parallel multi-triangle festoons, sloping nets, nets with cells filled with roundish spots, meander-shaped and volute-shaped curves), and other religious objects and images have strong analogies to cultural materials of the Middle-Late Neolithic of Western Europe. Only burial and ritual complexes of this entity were excavated (no settlements were identified). Finds included tin bronze and lead artifacts and domesticated animal bones. The Chemurchek people had close contact with peoples of the late Afanasievo culture who spread into Xinjiang, and later influenced the Elunino culture of Steppe Altai, the Karakol culture of Mountain Altai, and the Okunevo culture of Middle Yenisei basin.

    It's a minor lineage that was already present in Eastern Europe since the Mesolithic (EHG) and has nothing to do with the spread of PIE.
