Consequences of O&M 2018 (I): The latest West Yamna “outlier”

This is the first of a series of posts analyzing the findings of the recent Nature papers Olalde et al.(2018) and Mathieson et al.(2018) (abbreviated O&M 2018).

As expected, the first Y-DNA haplogroup of a sample from the North Pontic region (apart from an indigenous European I2 subclade) during its domination by the Yamna culture is of haplogroup R1b-L23, and it is dated ca. 2890-2696 BC. More specifically, it is of Z2103 subclade, the main lineage found to date in Yamna samples. The site in question is Dereivka, “in the southern part of the middle … Read the rest “Consequences of O&M 2018 (I): The latest West Yamna “outlier””

Olalde et al. and Mathieson et al. (Nature 2018): R1b-L23 dominates Bell Beaker and Yamna, R1a-M417 resurges in East-Central Europe during the Bronze Age

The official papers Olalde et al. (Nature 2018) and Mathieson et al. (Nature 2018) have appeared. They are based on the 2017 preprints at BioRxiv The Beaker Phenomenon And The Genomic Transformation Of Northwest Europe and The Genomic History Of Southeastern Europe respectively, but with a sizeable number of new samples.

Papers are behind a paywall, but here are the authors’ shareable links to read the papers and supplementary materials: Olalde et al. (2018), Mathieson et al. (2018).

Corded Ware culture contacts in the Baltic Sea region linked to immigrant potters

Article behind paywall Tracing grog and pots to reveal neolithic Corded Ware Culture contacts in the Baltic Sea region (SEM-EDS, PIXE) by Larsson et al., J. Archaeol. Sci. (2018) 91:77-91.

Abstract (emphasis mine):

The Neolithic Corded Ware Culture (CWC) complex spread across the Baltic Sea region ca. 2900/2800–2300/2000 BCE. Whether this cultural adaptation was driven by migration or diffusion remains widely debated. To gather evidence for contact and movement in the CWC material culture, grog-tempered CWC pots from 24 archaeological sites in southern Baltoscandia (Estonia and the southern regions of Finland and Sweden) were sampled for geochemical and micro-structural analyses.

The significance of the Tollense Valley in Bronze Age North-East Germany

An early Bronze Age causeway in the Tollense Valley, Mecklenburg-Western Pomerania – The starting point of a violent conflict 3300 years ago?, by Jantzen et al. (BERICHT RGK 95, 2014).

Excerpt (emphasis mine):

The causeway in the Tollense Valley, built of timber, stones, turf and sand, and documented over a length of more than 100 m, represents a unique finding from northern Germany. For the first time, part of a Bronze Age network of land routes could be made visible in the southern Baltic area.

Together with the other evidence, the archaeological remains suggest the construction of elaborate trackways

The concept of “Outlier” in Human Ancestry (III): Late Neolithic samples from the Baltic region and origins of the Corded Ware culture

I have written before about how the Late Neolithic sample from Zvejnieki seemed to be an outlier among Corded Ware samples (read also the Admixture analysis section on the IEDDM), due to its position in PCA, even more than its admixture components or statistical comparison might show.

In the recent update to Northern European samples in Mittnik et al. (2018), an evaluation of events similar to the previous preprint (2017) is given:

Computing D-statistics for each individual of the form D(Baltic LN, Yamnaya; X, Mbuti), we find that the two individuals from the early phase of the

mtDNA haplogroup frequency analysis from Verteba Cave supports a strong cultural frontier between farmers and hunter-gatherers in the North Pontic steppe

New preprint paper at BioRxiv, led by a Japanese researcher, with analysis of mtDNA of Trypillians from Verteba Cave, Analysis of ancient human mitochondrial DNA from Verteba Cave, Ukraine: insights into the origins and expansions of the Late Neolithic-Chalcolithic Cututeni-Tripolye Culture, by Wakabayashi et al. (2017).

Abstract:

Background: The Eneolithic (~5,500 yrBP) site of Verteba Cave in Western Ukraine contains the largest collection of human skeletal remains associated with the archaeological Cucuteni-Tripolye Culture. Their subsistence economy is based largely on agro-pastoralism and had some of the largest and most dense settlement sites during the Middle Neolithic in

Our monograph on North-West Indo-European (first draft) is out

I wrote yesterday about the recently updated Indo-European demic diffusion model.

Fernando López-Menchero and I have published our first draft on the North-West Indo-European proto-language. Our contribution concerns mainly phonetics, and namely two of its most controversial aspects: a common process of laryngeal loss and two series of velars for PIE.

There is also an updated linguistic model for the Corded Ware substrate hypothesis, which seeks to explain certain similarities between Germanic and Balto-Slavic, and between Balto-Slavic and Indo-Iranian, and potential isoglosses between the three.

The Tollense Valley battlefield: the North European ‘Trojan war’ that hints to western Balto-Slavic origins

It was reported long ago that genetic studies were being made on remains of a surprisingly big battle that happened in the Tollense valley in north-eastern Germany, at the confluence between Nordic, Tumulus/Urnfield, and Proto-Lusatian/Lusatian territories, ca. 1200 BC.

At least 130 bodies and 5 horses have been identified from the bones found. Taking into account that this is a small percentage of the potential battlefield, around 750 bodies are expected to be buried in the riverbank, so an estimated 4,000-strong army fought there, accounting for one in five participants killed and left on the battlefield.

Germanic–Balto-Slavic and Satem (‘Indo-Slavonic’) dialect revisionism by amateur geneticists, or why R1a lineages must have spoken Proto-Indo-European

I feel there has recently been an increase in references to quite old – and generally outdated – terms, such as Germano-Balto-Slavic and “Indo-Slavonic” (i.e. Satem), described as Late Indo-European dialects. This is happening in forums and blogs that deal with “Indo-European genetics”, and only marginally (if at all) with the main anthropological subjects that form Indo-European studies, that is Linguistics and Archaeology.

Firstly, let me go apparently against the very aim of this post, by supporting the common traits that these dialects actually share.

Satem Indo-European or Indo-Slavonic

Balto-Slavic is a complex dialect, whose known proto-history and … Read the rest “Germanic–Balto-Slavic and Satem (‘Indo-Slavonic’) dialect revisionism by amateur geneticists, or why R1a lineages *must* have spoken Proto-Indo-European”
