Thracian Origins, & the ''Aegeanisation'' of Southeast Europe. A work in progress ... some of the frames are off kilter.

Proximal Models for 'Thracians': (1) Aegean source: 'Minoans' or Kumtepe-6; plus (2) Central European: 'Kyatice_LBA' or 'Czech_Tumulus" Distal Model: 4 way admixture (1) ''Anatolian Farmer'' ~ 60%; (2) Yamnaya ~ 20%; (3) ''Iran_N'' ~ 15% (CHG fails); (4) Italian_HG ~ 5% (Iron Gates fails)

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 ?

The historic group which entered might have been Wusun or Yuezhi (whatever the case, part of the broader 'Saka complex'). Inner Asian officianados know the deets.

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.

The Myth of Population Replacement in aDNA Case 1: 'Anatolian Farmers replaced WHG" Not so. Two different populations initially avoided each other, then eventually mixed after few hundred years. Often, the new creole was dominated by WHG males.

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.

Also, raw % values are (whether determinesd via qpAdm, Admixture, or G25 methods), are kinda meaningless unless we know the original population sizes of mixing Groups. For ex: LBK communities 1000s , whilst WHG bands had dozens of people. So a 20% introgression is HUGE
