Indo-Iranian influence on West Uralic through the Catacomb culture

Featuredcatacomb-niche-graves-malopolska

In the recent Linderholm et al. (2020), I preferred to interpret the finding of R1b-P310* among late niche (catacomb) grave groups of Lesser Poland as derived from Late PIE – Late Uralic contacts, through a much earlier intrusion of late Repin/early Yamnaya chieftains among Late Trypillians.

This is one of the few aspects of the books where I tried to offer my own contribution to the field, by combining the Indo-Uralic concept (which supports a distinct evolution of laryngeals for PIE and PU) with a modified, ‘layered’ use of Koivulehto’s controversial and irregular PIE laryngeal borrowing as PU … Read the rest “Indo-Iranian influence on West Uralic through the Catacomb culture”

Early arrival of Steppe ancestry in Switzerland

late-neolithic-western-europe

Open access paper Ancient genomes reveal social and genetic structure of Late Neolithic Switzerland by Furtwängler et al. Nat. Commun. (2020).

Interesting excerpts (emphasis mine):

The ancient individuals from this study originate from 13 Neolithic and Early Bronze Age sites in Switzerland, Southern Germany, and the Alsace region in France. All samples taken from the individuals were radiocarbon dated.

The arrival of Steppe ancestry

Two distinct clusters can be identified and were also confirmed by ADMIXTURE analysis, one consisting of individuals dating to 4770–2500 calBCE, and one comprising individuals dating to 2900–1750 calBCE. The oldest individuals from the sites of

The Corded Ware culture, more complex than previously thought

corded-ware-malopolska-poland

Open access Corded Ware cultural complexity uncovered using genomic and isotopic analysis from south-eastern Poland, by Linderholm et al. Scientific Reports (2020).

Interesting excerpts (emphasis mine):

We have obtained genetic data from 19 individuals (16 of CWC and 3 of BBC). All examined individuals come from three geographical regions: the Rzeszów Foothills (part of the Subcarpathian Region; sites of Szczytna, Chłopice, Mirocin and Święte), the Małopolska Upland (Mistrzejowice, Proszowice, Bosutów, Pełczyska) and the Sokal Ridge (the western part of Volhynian Upland – site of Łubcze). All burials are of similar type exhibiting the same funeral rite with some differences

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

Fully Steppe-like Proto-Corded Ware Late Trypillians

late-trypillia-corded-ware

The genotypes from Human auditory ossicles as an alternative optimal source of ancient DNA, by Sirak et al. Genome Res. (2020), have been finally published by the Reich Lab, so we can get a sneak peek into what’s coming in future papers about the origins of R1a-rich Proto-Corded Ware and R1b-rich Italo-Venetic peoples.

NOTE. To avoid adding potential errors, I have merged the Reich Lab’s Curated Dataset (v. 42.4, March 1 2020) with these new samples before performing the qpAdm analyses. If you find something different with your files, you should probably check out this simple setting first. Read the rest “Fully Steppe-like Proto-Corded Ware Late Trypillians”

Earliest R1a-Z93…from Late Trypillia in the Podolian-Volhynian Upland!

chalcolithic-yamnaya-corded-ware

Recently, the preprint by Sirak et al. biorXiv (2019), Human auditory ossicles as an alternative optimal source of ancient DNA, was published in Genome Res. (2020), and the corresponding samples were finally uploaded to ENA.

I have been trying to get my hands on sample GLAV_14, a male from the Late Eneolithic site Glăvăneştii Vechi, classified as Romania Bronze Age (ca. 3500-3000 BC), mtDNA T1a1, referenced as investigated first in the study:

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”
