Proto-Turkic homeland

This post is part of a draft on South Siberian language homelands and Sprachbünde.

The following text contains a description of Proto-Turkic and its main dialectal split. Contacts with Samoyed, Ob-Ugric, Iranian, Yeniseian, Tocharian, Chinese and Mongolic, as well as palaeolinguistics, hydronymy, and ethnonymy are taken into account to pinpoint the succeeding homelands and expansion territories. The archaeological-archaeogenetic discussion is focused on the Middle and Late Bronze Age Altai Mönkhkhairkhan and Deer Stone-Khirigsuur Complex and related groups, as well as on Ulaanzukh; Early Iron Age “Scytho-Siberian” Pazyryk & Uyuk and Slab Grave cultures; and on the Late … Read the rest “Proto-Turkic homeland”

R1b-rich Proto-Indo-Europeans show genetic continuity in Asia

Another preprint came out at the same time as Wang et al. (2020), from the Jena Lab of the Max Planck Society: A dynamic 6,000-year genetic history of Eurasia’s Eastern Steppe, by Jeong, Warinner, et al. bioRxiv (2020).

NOTE. I have now updated the Ancient DNA Dataset, the Prehistory Atlas – with PDF and GIS files including Y-DNA and mtDNA of all newly reported samples (starting with the Neolithic) – as well as the PCA files with those from Wang et al. (2020).

The conclusions are similar, but with some interesting twists. Relevant excerpts (emphasis mine), … Read the rest “R1b-rich Proto-Indo-Europeans show genetic continuity in Asia”

Yamnaya-like Chemurchek links Afanasievo with Iron Age Tocharians

New preprint by the Jena-Reich labs, The Genomic Formation of Human Populations in East Asia, by Wang et al. bioRxiv (2020).

Interesting excerpts (emphasis mine):

Mongolia Neolithic cluster

The three most ancient individuals of the Mongolia ‘East’ cluster are from the Kherlen River region of eastern Mongolia (Tamsag-Bulag culture) and date to 6000-4300 BCE (this places them in the Early Neolithic period, which in Northeast Asia is defined by the use of pottery and not by agriculture). These individuals are genetically similar to previously reported Neolithic individuals from the cis-Baikal region and have minimal evidence of West Eurasian-related admixture

Samoyedic shows Yeniseic substrate; both influenced Tocharian

Open access paper The deviant typological profile of the Tocharian branch of Indo-European may be due to Uralic substrate influence by Peyrot, Indo-European Linguistics (2019).

NOTE. This seems to be part of the master’s thesis by Abel Warries, but the paper is authored only by Peyrot.

Interesting excerpts (emphasis mine):

1. The stop system

The loss in Tocharian of the Proto-Indo-European obstruent distinctions conventionally noted as voice and aspiration is a very strong indication of foreign influence. Since Proto-Indo-European roots mostly have at least one stop, and often two, the merger of all three stop series into one must have

The expansion of Indo-Europeans in Y-chromosome haplogroups

I have compiled for two years now the reported Y-DNA and mtDNA haplogroups of ancient DNA samples published, including also SNPs from analysis of the BAM files by hobbyists.

Y-DNA timeline

Here is a video with a timeline of the evolution of Indo-European speakers, according to what is known today about reconstructed languages, prehistoric cultures and ancient DNA:

NOTE. The video is best viewed in HD 1080p (1920×1080) with a display that allows for this or greater video quality, and a screen big enough to see haplogroup symbols, i.e. tablet or greater. The YouTube link is here. The … Read the rest “The expansion of Indo-Europeans in Y-chromosome haplogroups”

Proto-Tocharians: From Afanasievo to the Tarim Basin through the Tian Shan

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”

Iron Age Tocharians of Yamnaya ancestry from Afanasevo show hg. R1b-M269 and Q1a1

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,

Early Iranian steppe nomadic pastoralists also show Y-DNA bottlenecks and R1b-L23

New paper (behind paywall) Ancient genomes suggest the eastern Pontic-Caspian steppe as the source of western Iron Age nomads, by Krzewińska et al. Science (2018) 4(10):eaat4457.

Interesting excerpts (emphasis mine, some links to images and tables deleted for clarity):

Late Bronze Age (LBA) Srubnaya-Alakulskaya individuals carried mtDNA haplogroups associated with Europeans or West Eurasians (17) including H, J1, K1, T2, U2, U4, and U5 (table S3). In contrast, the Iron Age nomads (Cimmerians, Scythians, and Sarmatians) additionally carried mtDNA haplogroups associated with Central Asia and the Far East (A, C, D, and M). The absence of East Asian mitochondrial

A study of genetic diversity of three isolated populations in Xinjiang using Y-SNP

New open access paper (in Chinese) A study of genetic diversity of three isolated populations in Xinjiang using Y-SNP, by liu et al. Acta Anthropologica Sinitica (2018)

Abstract:

The Keriyan, Lopnur and Dolan peoples are isolated populations with sparse numbers living in the western border desert of our country. By sequencing and typing the complete Y-chromosome of 179 individuals in these three isolated populations, all mutations and SNPs in the Y-chromosome and their corresponding haplotypes were obtained. Types and frequencies of each haplotype were analyzed to investigate genetic diversity and genetic structure in the three isolated populations. The results
