On Fatyanovo and the survival of R1a-Z93* among Mari-Permians

The recent preprint on ancient DNA from Veretye, Lyalovo/Volosovo and Fatyanovo from Saag et al. (2020) has been published in Science Advances Vol. 7, no. 4, eabd6535, and with it the BAM files.

Here are the Y-SNP calls from the files, following the FTDNA Haplotree standard, with Fatyanovo individuals in alphabetical order:

Veretye PES001 from Peschanitsa (ca. 10785–10626 calBC), mtDNA U4a1, Y-DNA R1aM459YP1301(pre-YP1272?), with 2 SNPs derived – YP1306 (T-C, 5 reads) and Y12474 (T-A, 6 reads) – and 46 SNPs ancestral at the YP1272 level. A sample with 5× coverage that

The complexities of 3rd millennium Steppe-related migrations

Open access paper Mobility and Social Change: Understanding the European Neolithic Period after the Archaeogenetic Revolution, by Martin Furholt, J. Archaeol. Res. (2021).

Content under CC-BY license. Interesting excerpts (emphasis mine, stylistic changes for clarity):

This detailed picture of Caucasian population history shows that the initial assertion in the 2015 papers, namely of a one-way migration from east to west, was a simplification supported by a variant of admixture analyses that featured Yamnaya as one unified genetic element (e.g., Haak et al. 2015, fig. 3), which led to calculations of Corded Ware individuals showing 75% Yamnaya ancestry.

Proto-Uralic Homeland (VI): Mythology & Metallurgy

This post is part of a draft on palaeolinguistics and the Proto-Uralic homeland. See below for the color code of protoforms.

PU (Saa., Fi., Md., Ma., P, Ms.?, Kh., Smy.?) *wäśkä (*waśki?) ‘copper; ore, brass’ (UEW Nº 1123; Kallio 2006: 6). Irregular cognates suggest it might have been borrowed during the split-up of Proto-Uralic (cf. Aikio 2015: 42). However, compare potentially regular cognates from *wäskä in PFi. *vaski ‘ore, copper, bronze; brass’ (Kallio 2012: 167; Zhivlov 2014: 115), PSaa. *weśkä ‘copper; brass’, Md.

R1a-Z93-rich Classical CWC-like Fatyanovo replaced Volosovo

Open access Genetic ancestry changes in Stone to Bronze Age transition in the East European plain, by Saag et al. bioRxiv (2020).

Interesting excerpts (emphasis mine):

Y-DNA chromosome haplogroup

(…) the Bronze Age Fatyanovo Culture individuals [] maternal (subclades of mtDNA hg U5, U4, U2e, H, T, W, J, K, I and N1a) and paternal (chrY hg R1a-M417) lineages were ones characteristic of CWC individuals elsewhere in Europe. Interestingly, in all individuals for which the chrY hg could be determined with more depth (n=6), it was R1a2-Z93, a lineage now spread in Central and South Asia, rather than the

Genetic continuity among Uralic-speaking cultures in north-eastern Europe

The recent study of Estonian Late Bronze Age/Iron Age samples has shown, as expected, large genetic continuity of Corded Ware populations in the East Baltic area, where West Uralic is known to have been spoken since at least the Early Bronze Age.

The most interesting news was that, unexpectedly for many, the impact of “Siberian ancestry” (whatever that actually means) was small, slow, and gradual, with slight increases found up to the Middle Ages, compatible with multiple contact events in north-eastern Europe. Haplogroup N became prevalent among Finnic populations only through late bottlenecks, as research of modern … Read the rest “Genetic continuity among Uralic-speaking cultures in north-eastern Europe”

Corded Ware—Uralic (II): Finno-Permic and the expansion of N-L392/Siberian ancestry

This is the second of four posts on the Corded Ware—Uralic identification:

I read from time to time that “we have not sampled Uralic speakers yet”, and “we are waiting to see when Uralic-speaking peoples are sampled”. Are we, though?

Proto-language homelands are based on linguistic data, such as guesstimates for dialectal evolution, loanwords and phonetic changes for language contacts, toponymy … Read the rest “Corded Ware—Uralic (II): Finno-Permic and the expansion of N-L392/Siberian ancestry”

Common pitfalls in human genomics and bioinformatics: ADMIXTURE, PCA, and the ‘Yamnaya’ ancestral component

Good timing for the publication of two interesting papers, that a lot of people should read very carefully:

ADMIXTURE

Open access A tutorial on how not to over-interpret STRUCTURE and ADMIXTURE bar plots, by Daniel J. Lawson, Lucy van Dorp & Daniel Falush, Nature Communications (2018).

Interesting excerpts (emphasis mine):

Experienced researchers, particularly those interested in population structure and historical inference, typically present STRUCTURE results alongside other methods that make different modelling assumptions. These include TreeMix, ADMIXTUREGRAPH, fineSTRUCTURE, GLOBETROTTER, f3 and D statistics, amongst many others. These models can be used both to probe whether assumptions of the model

North-Eastern Europe in the Stone Age – bridging the gap between the East and the West

Interesting PhD thesis The Stone Age of north-eastern Europe 5500–1800 calBC : bridging the gap between the East and the West by Kerkko Nordqvist (2018).

Some interesting excerpts:

On the Corded Ware and related cultures

The arrival of Corded Ware is without a doubt the clearest example of migration recognized in Finnish Stone Age archaeology. Its appearance has been understood to result from the movement of a new population from the southern or southeastern Baltic Sea area to the southern and western coasts of Finland (Europaeus 1922: 137; Luho 1948: 57; Edgren 1970: 62; Matiskainen 1994: 14) (Fig. 36).

More evidence on the recent arrival of haplogroup N and gradual replacement of R1a lineages in North-Eastern Europe

A new article (in Russian), Kinship Analysis of Human Remains from the Sargat Mounds, Baraba forest-steppe, Western Siberia, by Pilipenko et al. Археология, этнография и антропология Евразии Том 45 № 4 2017, downloadable at ResearchGate.

Abstract:

We present the results of a paleogenetic analysis of nine individuals from two Early Iron Age mounds in the Baraba forest -teppe, associated with the Sargat culture (ﬁ ve from Pogorelka-2 mound 8, and four from Vengerovo-6 mound 1). Four systems of genetic markers were analyzed: mitochondrial DNA, the polymorphic part of the amelogenin gene, autosomal STR-loci, and those of the Y-chromosome.
