    Default Ancestral heterogeneity of ancient Eurasians (Shriner 2018)

    So far it's a preprint, but it looks juicy nonetheless. Especially the last clause of the last sentence.

    Ancestral heterogeneity of ancient Eurasians
    Supervised clustering or projection analysis is a staple technique in population genetic analysis. The utility of this technique depends critically on the reference panel. The most commonly used reference panel in the analysis of ancient DNA to date is based on the Human Origins array. We previously described a larger reference panel that captures more ancestries on the global level. Here, I reanalyzed DNA data from 279 ancient Eurasians using our reference panel, finding substantially more ancestral heterogeneity than has been reported. This reanalysis provides evidence against a resurgence of Western hunter-gatherer ancestry in the Middle to Late Neolithic and evidence for a common ancestor of farmers characterized by Western Asian ancestry, a transition of the spread of agriculture from demic to cultural diffusion, at least two migrations between the Pontic-Caspian steppes and Bronze Age Europe, and a sub-Saharan African component in Natufians that localizes to present-day southern Ethiopia.
    Thanks to @BlessedbyHorus for bringing this to my attention.

    @Power77 Are you going to "Put some Respect" on your Omotic and North African Ancestors now?

    "Buh...Buh... The Natufians had LITTLE relations to Africans!!"

    "They were mostly Eurasian!"

    This is what happens when people throw away fair constructive criticism as Afrocentric nonsense. We tried telling them that the large E ancestry in the Natufians was the elephant in the room. But nope...

    Wow. Checkmate. Wow. I believed @Polako , @EliasAlucard , etc... Because they had so much passion in their convictions. Like they had the inside scoop on the shit...

    I am unlike many of the previous posters, in this thread, as I try to have as little bias as possible. But, yes Natufians and all successive, neighboring MENA people have legit East African-like admixture at non-negligible levels, and it's no "quirk of ADMIXTURE", it's no "Nubian slaves". It's basal, it has something to do Y-DNA E, and it can easily detected using modern ADMIXTURE (i.e. "Eurogenes"). *drops mic*

    That was your first mistake. Believing Polako about anything genetic outside of Indo-Europeans. He should just stick to that.

    .
    Not a good comparison IMO.
    Polako > EliasAlucard

    At least Polako has spent some time doing some actual analysis of African and Non African genomes.
    His failure to predict or even entertain what we are seeing coming from these latest studies is mostly due to his disinterest in African specific genetics and history.

    Seems like this Ethiopian-Natufian autosomal DNA admixture completely disappeared in Middle Easterners, in that case

    And you do understand that at this point, it's not so much mine and Polako's opinion, as it is an established fact, that the Natufians lacked Negroid admixture?

    Quote Originally Posted by Lazaridis et al. 2016
    Craniometric analyses have suggested that the Natufians may have migrated from north or sub-Saharan Africa, a result that finds some support from Y chromosome analysis which shows that the Natufians and successor Levantine Neolithic populations carried haplogroup E, of likely ultimate African origin, which has not been detected in other ancient males from West Eurasia (Supplementary Information, section 6). However, no affinity of Natufians to sub-Saharan Africans is evident in our genome-wide analysis, as present-day sub-Saharan Africans do not share more alleles with Natufians than with other ancient Eurasians (Extended Data Table 1).
    https://www.biorxiv.org/content/bior...59311.full.pdf

    So whatever they did in this new study, seems to be at odds with both Lazaridis and the rest of the independent genetics crowd out there.

    Anyway it doesn't really matter if the Natufians had Negroid admixture; it doesn't change anything if they did. Ancient Egyptians were still not blacks and that's like, the ultimate racial pwnage

    In fact, they are not even the Europeans in strict sense, meaning European as in bearing the responsibility and understanding of European interests. Poland has always been an subordinate country, on one side sucking German dick, on the other side -- Russian one, some kind of "novice" europeans, who are full of inferiority complexes, hysteria and obsessity neuroses. This is also true for all Baltic countries

    Maybe so! However he has said some foolish shit outside of Indo-European genetics that can't be ignored. Interest or not, that's not an excuse.
