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

middle-bronze-age-andronovo-horizon

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

late-bronze-age-mongolia-tarim-china

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

Ancient phylogeography: spread of haplogroups R1b, R1a and N

haplogroups-r1a-r1b-q

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 archaicRead the rest “Ancient phylogeography: spread of haplogroups R1b, R1a and N”

The expansion of Indo-Europeans in Y-chromosome haplogroups

yamnaya-corded-ware-y-dna-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”

The Lusatian culture, the most likely vector of Balto-Slavic expansions

early-bronze-age-languages-europe

New archaeological paper (behind paywall) New evidence on the southeast Baltic Late Bronze Age agrarian intensification and the earliest AMS dates of Lens culinaris and Vicia faba, by Minkevičius et al. Vegetation History and Archaeobotany (2019).

Interesting excerpts (emphasis mine):

Arrival of farming in the south-east Baltic

The current state of research reveals no firm evidence of crop cultivation in the region before the LBA (Piličiauskas et al. 2017b; Grikpėdis and Motuzaitė-Matuzevičiūtė 2018). Current archaeobotanical data firmly suggest the adoption of farming during the EBA to LBA transition. (…) By comparison, in other parts of N Europe subsistence economy

Recent paper (behind paywall) Multi-scale archaeogenetic study of two French Iron Age communities: From internal social- to broad-scale population dynamics, by Fischer et al. J Archaeol Sci (2019).

In it, Fischer and colleagues update their previous data for the Y-DNA of Gauls from the Urville-Nacqueville necropolis, Normandy (ca. 300-100 BC), with 8 samples of hg. R, at least 5 of them R1b. They also report new data from the Gallic cemetery at Gurgy ‘Les Noisats’, Southern Paris Basin (ca. 120-80 BC), with 19 samples of hg. R, at least 13 of … Read the rest “More Celts of hg.

Volosovo hunter-gatherers started to disappear earlier than previously believed

Interesting excerpts (emphasis mine):

The Sakhtysh micro-region is located in the Volga-Oka interfluve, along the headwaters of the Koyka River in the Ivanovo Region, central European Russia (Fig. 1). The area has evidence of human habitation from the Early Mesolithic to the Iron Age, and includes altogether 11 long-term and seasonal settlements (Sakhtysh I–II, IIa, III–IV, VII–XI, XIV) and four artefact scatters (sites

More Hungarian Conquerors of hg. N1c-Z1936, and the expansion of ‘Altaic-Uralic’ N1c
