    Thats because of the low coverage:
    The sample-pool consisted of 29 males and 16 females. We performed whole mitochondrial DNA and 3000 nuclear SNP target-enrichment combining with shallow shotgun sequencing.

    Well, I hope they will do full genomes with decent coverage.

    Autosomal DNA is already there (although the quality of the samples is not too high), some of you must have missed it. They were ~45% East Eurasian and resembled present-day Mansis and Siberian Tatars.

    The five Uyelgi samples with an average of 22,540 SNPs show the most similar ancestry cluster proportions to present-day Mansis and Irtysh-Barabinsk Tatars. The structure of ancestry components is different from Uylegi in case of the Okunevo that shows more North Siberian and East-Asian related ancestry. Closest ancient proxies in the current published databases are the Iron Age Central Sakas and early medieval Kimak from present-day North Kazakhstan. The Central Sakas (Inner Asian Scythians) were modelled as a two-way mixture of Late Bronze Age pastoralists (56%) and southern Siberian hunter-gatherers (44%) by Damgaard et al.16, which scenario is plausible for the Uyelgi population as well.

    According to the admixture analysis, you do not get Uyelgi samples, if you mix Sintashta and Shamanka EBA. Sintashta has ca 20% Basal (black), Uyelgi has none. Moreover, Uyelgi has as much European (blue) component as Sintashta or more. In an even admixture, Uyelgi should have c. 10% European blue component.

    In addition to that, N-L1026 has not been detected in Baikal Neolithic or Baikal EBA.

    We need a different story.

    The samples are very low quality, you can see that the Uyelgi individuals even have quantized ancestry proportions in ADMIXTURE (!) We cannot draw overly specific conclusions from the autosomal analysis of this paper, which is why the autosomes are not presented front and center.

    Of course, it is a great pity that the quality is this, and I am waiting to see the result of the high quality samples. At the moment, this admixture analysis is all we have.

    I do not think that my observations were overly specific.

    From the linguistic point of view, I do not think that anybdy thinks that Ugric populations arose in a mixture between Sintashta and Baikal Bronze Age.

    Just by looking at the location of Avars' paternal N in the N haplotree, I think there's a good reason to reconsider Gyula László's Avar-Magyar continuity theory. It may well be that Avar N-B197 was a part of East Uralic expansion. The dispersion time of of N-L1026 TMRCA 4600 years > N-Y6058 TMRCA 4600 years > N-B197 4600 years seem to be approximately the same as the one of Uralic. Like in the case of Hungarian etc. N-L1026 > N-Z1936 TMRCA 4100 years, some part of N-B197 possibly was in contact with Oghur Turkic tribes, but further in Siberia, however not switching the language entirely.
