    I figured it was common sense that Koreans are genetically in between (coastal) Northern Han and Japanese. But I am ethnic Chinese, and born + raised in the US. That may be influencing my perspective.

    Sorry to see ybmpark got banned. I wonder what they wrote to provoke the mods...

    Apparently ymbpark made mention of intellectual differences between people of separate populations. As we know, that's just not permitted in Western social or scientific discourse in any way. The user seems to have been miffed about a previous comment I made about the Salkhit skullcap found in Mongolia being noted for having archaic features. Which I made just to juxtapose how remote ancestors from the north can be as disparate as those from the south. ymbpark may have taken it as an affront to Koreans somehow. However, I have a lot of respect for Koreans and the progress they made in their society.

    And then you can add the Q1a1as from Ulaanzuukh sites to the list as well if you didn't already (and the ones in Jeong et al.).

    Are these lineages so closely related that they imply direct kinship? Or in other words, do we have something similar going on with the Megalithic tombs in Atlantic Europe?

    Because it is rather peculiar that this lineage is super common in these burials but not nearly as present in later samples from the Xiongnu period with significant amounts of Slab Grave or Ulaanzuukh ancestry. If the prevalence of this lineage reflects the average population of the time then it's odd why we see much more diversity later on.

    Probably the most interesting discovery so far, Chemurchek sample that belongs to an extremely rare subclade directly below Z2103, and parallel to the much more numerous and widespread M12149:


    I12978; 2570-2476 BC; Yagshiin khodoo, Bulgan sum, Khovd aimag, Mongolia; Chemurchek_EBA; R1b1a1a2a2-Z2103>FT130482 (xFT130500)


    Z2103 level: Z2103/CTS1078+ G>C (2C)

    FT130482 level: FT130482+ A>G (2G); FT165136+ A>T (1T)

    FT130482>FT130500 level: FT130139- G>C (1G); FT130338- A>G (2A); FT130526- G>A (1G); FT130641- T>A (7T); FT130820- A>G (1A); FT130986- T>C (2T); FT131378- A>G (1A); FT132114- C>T (1C)

    FT130482>FTA3897 level: *no calls*

    Since I can't find the appropriate topic on N subforum, I might as well post it here since two of the samples from this paper are concerned. Until not long ago, N-L666 block contained 80 SNPs, but thanks to several ancient samples, and a modern sample from China, it can now be split into six separate levels:


    Y3037 is the youngest level, and it is defined by 15 SNPs that are derived in modern men that belong to its downstream clades F1101 and P43, but are ancestral in Baikal_EN samples from Shamanka and Lokomotiv sites.

    CTS4202 level is defined by 3 SNPs that are derived in Baikal_EN samples, but are ancestral in irk007, a closely related Baikal_EN sample that had split slightly earlier.

    L666 level is defined by 14* SNPs that are derived in Baikal_EN and irk007, but are ancestral in I12976, a LBA sample from Mongolia.

    Y3048 level is defined by 7* SNPs that are derived in Baikal_EN, irk007 and I12975, but ancestral in I1202, a Yankovsky_IA sample from the Russian Far East.

    F4309 level is defined by 31* SNP that are derived in Baikal_EN, irk007, I12975 and I1202, but ancestral in modern Chinese sample from Shaanxi province.

    F1360 is the oldest level, defined by 10 SNPs that are derived in all mentioned ancient samples and in modern Chinese.

    *Since I1202 and I12976 are 1240K sequenced, a lot of SNPs are not covered, especially at F4309 level. So we might expect that some SNPs from this level will be moved to downstream levels Y3048 and L666 when we get more shotgun ancient samples.

    This just amazing work Privbislav!
    Quoted from this Forum:

    "Which superman haplogroup is the toughest - R1a or R1b? And which SNP mutation spoke Indo-European first? There's only one way for us to find out ... fight!"

    " Cheddar man was an ugly brown dwarf ... I guess some people identify very strongly with their conquering aryan forefathers that the thought of having subhuman swarthy farmer blood running through their veins is absolutely appalling ... "
