The Tocharian (Agni-Kuchean) Genetic Trail
How much Afansievo ancestry in Iron Age Xinjiang ?
Well its there, but Andronovo, Baikal and East Asian ancestry are prevalent.
Perhaps the linguistic stem for 'Tocharian' does derive from from a ''centum speaking' Afansievo group. But what about the Andronovo groups which entered Xingjian 1500 years before the Saka hal.science/hal-03220976v1 ? If this extends into the historic Tarim, we need to be conceptualy equipped to tackle the sociolinguistic corollary. Do the "Agni'' have an Indo-Iranian twang ?
Kudos, but two errors are perpetuated.
1. The Epicardial is mischaracterised, perpetually.
2. The ''TRB derives from Michelsberg'' falsehood. The 2 'cultures' are different, have different genomes & Y-DNA, lack IBD. McColl et al cite only one inadequate Ref, inoring vast amounts of continental literature, making their appraisal seem... amateurish
To fix things:
Excited to share our preprint on the spread of megaliths in Neolithic Europe. Trade networks formed in the wake of migrations, and megaliths then spread within those networks. On their own, migration and cultural diffusion tell an incomplete story. biorxiv.org/content/10.64898…
4. West Asia: Kotias_MUP (Georgia 25000bp) is close to Europe_UP. However, later Caucasus hunters diverge, & plot with Iranian samples ('PPN Iraq' is also in this cluster). These might have ancestry from a yet unsampled 'Eur_4, or Basal" Lineage.
By contrast, Pinarbasi (15000bp Anatolia) has close affinities with WHG. 'Natufians' look like a mix of Pinarbasi & north Africans (represented by Iberomaurisians from Morroco).
5. East Asia: there is metacontinuity from the early Paleolithic to Mesolithic (& Neolithic). Later East Asians, Papuans, Australians, in some shape or form descend from this Founder Population 40000 yrs ago.
6. Siberia: Yana sits between 'UP Europe' and "East Asia', as expected. However, younger Siberians (Mal'ta, Afontova) are shifted toward the Caucasus-Iran cluster.
On the flip side, we hear about ‘millennia old continuity’ narratives for Anatolia, the Aegean & Caucasus, despite clear evidence to the contrary. I will address this in Future.
Thus, despite the excellent advancements in aDNA tools & extraction methods, studies often remain cognitively deficient. I don’t think this will change until people like Reich & Lazarides continue to flood the media with their biased, poorly educated perspectives.
@DanTabin feel free to learn these basics.
There was no BB material culture associated with those individuals (phase 2 Bury) .

Somebody help this poor bloke out
Lazaridis & Reich Lab Co. present a problematic reconstruction of East Anatolian history for several reasons (1) they ignore context, and in this case the R1b-V1636 from Arslantepe is a sacrificial burial (from Skourtianoti ART038 - 'lying on top of stone slabs closing the Royal tomb. Probably sacrificed. Dating of human bone: 3361-3105 cal BCE (4534 ± 27 BP, MAMS-34112). (2) Lazaridis' models are poorly executed, ART-018, despite being R1b, has less (almost zero) steppe ancestry than KAx populations, suggesting that ART018 had indeed been part of a non-IE KAx meta-group; (3) Their explanation that the KAx expansion 'erased' steppe ancestry in East and C. Anatolia doesn't hold, because KAx expanded c. 3200 BC, whilst we have Chalcolithic samples from from E-C Ant dating to 4000 and 3000 BC, which lack steppe ancestry. Hence in addition to poor analysis, they seem to be historically mis-informed; (4) We have a clear trace of steppe ancestry in western Anatolia, coupled with a clear Y-DNA signal
