Article in press (behind paywall) Mitochondrial DNA of domesticated sheep confirms pastoralist component of Afanasievo subsistence economy in the Altai Mountains (3300–2900 cal BC), by Hermes et al. Archaeological Research in Asia (2020).
Previous zooarchaeological research at Afanasievo settlement and mortuary sites argues for the exploitation of both domesticated and wild cattle, sheep, and goats (Derevianko and Molodin, 1994; Gryaznov, 1999; Kosintsev, 2005; Kosintsev and Stepanova, 2010; Pogozheva, 2006). However, the biogeographic distribution of Siberian ibex (Capra sibirica) and argali sheep (Ovis ammon) includes the Altai (Baskin and Danell, 2003), while aurochsen (Bos primigenius) were also likely

Most of the Lake Baikal individuals occupied the space on a “ANE-NEA” cline running between “Northeast Asian” (NEA) ancestry represented by Neolithic hunter-gathers from the Devil’s Gate in the Russian Far East (Sikora et al., 2019, Siska et al., 2017), and the ANE ancestry represented by Upper Paleolithic Siberian individuals MA1, AfontovaGora 2 (AG2), and AfontovaGora 3 (AG3) (Fu et al., 2016, Raghavan et al.,

The previous post showed the potential use of TreeToM to visualize ancient DNA samples in maps together with their Y-DNA phylogenetic trees. I have written Newick trees for Y-chromosome haplogroups R1b-L388 (encompassing R-V1636 and R-P297, which in turn split into R-M73 and R-M269), R1a, and N.
I have reviewed some of the BAM files from my previous bulk analyses with YLeaf v.2, to add information that I had not previously included in the All Ancient DNA Dataset, and which might be relevant to the proper depiction of phylogenetic trees; in particular, positive and negative SNPs potentially distinguishing archaic… Read the rest “Ancient phylogeography: spread of haplogroups R1b, R1a and N”
A reader commented recently that there is little information about Indo-Europeans from Central and East Asia in this blog. Regardless of the scarce archaeological data compared to European prehistory, I think it is premature to write anything detailed about population movements of Indo-Iranians in Asia, especially now that we are awaiting the updates of Narasimhan et al (2018).
Furthermore, there was little hope that Tocharians would be different than neighbouring Andronovo-like populations (see a recent post on my predicted varied admixture of Common Tocharians), so the history of both unrelated Late PIE languages would have had to be … Read the rest “Proto-Tocharians: From Afanasievo to the Tarim Basin through the Tian Shan”
The latest papers from Ning et al. Cell (2019) and Anthony JIES (2019) have offered some interesting new data, supporting once more what could be inferred since 2015, and what was evident in population genomics since 2017: that Proto-Indo-Europeans expanded under R1b bottlenecks, and that the so-called “Steppe ancestry” referred to two different components, one – Yamnaya or Steppe_EMBA ancestry – expanding with Proto-Indo-Europeans, and the other one – Corded Ware or Steppe_MLBA ancestry – expanding with Uralic speakers.
The following maps are based on formal stats published in the papers and supplementary materials from 2015 until today, mainly on … Read the rest “Yamnaya ancestry: mapping the Proto-Indo-European expansions”
New open access Ancient Genomes Reveal Yamnaya-Related Ancestry and a Potential Source of Indo-European Speakers in Iron Age Tianshan, by Ning et al. Current Biology (2019).
Interesting excerpts (emphasis mine, changes for clarity):
Here, we report the first genome-wide data of 10 ancient individuals from northeastern Xinjiang. They are dated to around 2,200 years ago and were found at the Iron Age Shirenzigou site. We find them to be already genetically admixed between Eastern and Western Eurasians. We also find that the majority of the East Eurasian ancestry in the Shirenzigou individuals is related to northeastern Asian populations,

Matrilineal and patrilineal genetic continuity of two iron age individuals from a Pazyryk culture burial, by Tikhonov, Gurkan, Peler, & Dyakonov, Int J Hum Genet (2019).
Relevant excerpts (emphasis mine):
Of particular interest to the current study are the archaeogenetic investigations associated with the exemplary mound 1 from the Ak-Alakha-1 site on the Ukok Plateau in the Altai Republic (Polosmak 1994a; Pilipenko et al. 2015). This typical Pazyryk “frozen grave” was dated around 2268±39 years before present (Bln-4977) (Gersdorff and Parzinger 2000). Initial anthropological findings suggested an undisturbed dual inhumation comprising “a middle-aged European- type man” and “a young

Open access paper Bronze Age population dynamics and the rise of dairy pastoralism on the eastern Eurasian steppe, by Jeong et al. PNAS (2018).
Interesting excerpts (emphasis mine):
To understand the population history and context of dairy pastoralism in the eastern Eurasian steppe, we applied genomic and proteomic analyses to individuals buried in Late Bronze Age (LBA) burial mounds associated with the Deer Stone-Khirigsuur Complex (DSKC) in northern Mongolia. To date, DSKC sites contain the clearest and most direct evidence for animal pastoralism in the Eastern steppe before ca. 1200 BCE.
