Oral communication Ancient DNA and the New Science of the Human Past by David Reich (March 3, 2021).
I noticed this interesting slide called “Caught red-handed”, at approximately 45m 17s, where David Reich asserts that sampled Corded Ware populations had many “close cousins” with Yamnaya-related populations “within generations”. The method could also be used, always according to Reich, to identify “who the Yamnaya mixed with to form groups like Corded Ware”.
NOTE. Notice also the the number of new sampled individuals from Khvalynsk, Ekaterinovka, and new Yamnaya groups from Chelyabinsk, Urals, Volga, Don, Moldova, and Romania.
This represents the … Read the rest “IBD sharing between Corded Ware and Yamnaya-related populations”
Today is International Mother Language Day, a day as good as any other to start or continue learning Proto-Indo-European.
Fernando López-Menchero has just published the 3rd version of his Proto-Indo-European self-study book, A Practical Guidebook for Modern Indo-European Explorers, updating the previously published 1st version (2018). It includes:
- Multiple corrections to the already published lessons 1-30, based on many comments from readers, received by email and through the Modern Indo-European Group.
- The addition of previously announced Part II of the Guidebook, now published as lessons 31-42 and Appendices.
- Corrections and updates to the supplementary materials,

Recent paper (
behind paywall) Runes from Lány (Czech Republic) – The oldest inscription among Slavs. A new standard for multidisciplinary analysis of runic bones by Macháček et al. J. Archaeol Sci (2021).
Interesting excerpts (emphasis mine):
To date no archaeological find is generally accepted as evidence for a direct contact between Germanic tribes and Early Slavs in Central Europe (Brather, 2004). Here we report a novel archaeological find in support of a direct contact: a rune-inscribed fragment of a bone from the late 6th century found in a Slavic settlement. Runes are an alphabetic script, called fuþark,

I have been updating the Ancient DNA Dataset with date estimates published in the recent preprint by Sedig, Olalde, Patterson & Reich bioRxiv (2020), and it had a reference to some interesting new samples from Khvalynsk, showing tight family connections.
Information below is taken from the preprint and from the latest version of the Reich Lab’s Allen Ancient DNA Resource (AADR). Information about the three published Khvalynsk samples is taken from Mathieson et al. Nature (2015) supplementary materials, and each ID features a different font color in the text below for clarity’s sake.

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 BAM files from Egfjord et al. (2021) are out, and Y-SNPs of two-year-old Nordic MN_LN/LN migrant Gjerrild 5 (ca. 2284-2035 calBC) were accurately reported, which means that the sample will need to be labelled R1b>L754>L389>(pre-?)V1636, since one derived read Y125110+ (A->G) in this and one ancestral in a Progress2 sample, PG2001, cannot be used to infer anything certain.
NOTE. It has one derived read (A-T) for FT3897 at the R1b>L754>L389>V1636>Y83069 level, but the other 8 SNPs ancestral, which is not really helpful to define a potential pre-Y83069 branch, given the doubts above. A possible relative could … Read the rest “The Last of the Single Gravers”
Open access Genomic Steppe ancestry in skeletons from the Neolithic Single Grave Culture in Denmark, by Egfjord et al. PLoS One (2021).
Relevant excerpts (emphasis mine, content under CC-BY):
Gjerrild stone cist
The Gjerrild stone cist in northern Djursland, eastern Jutland, is remarkable for containing the largest and best-preserved assemblage of SGC skeletons known from Denmark. From this follows a unique opportunity to obtain information on the genetic ancestry of people representing the SGC in Denmark. In the cultural history of Neolithic Denmark, northern Djursland is peculiar as this area lacks finds from the final TRB period but

This is an update to the data from Human population dynamics and Yersinia pestis in ancient northeast Asia, by Kılınç et al. Science Advances (2021).
Files have been released, and some of them are huge, so it might take me some time to analyze them all and include specific subclades in the Ancient DNA Dataset.
For the moment, the sample I highlighted in the previous post, kra001 (2336-2135 calBCE), mtDNA C4b1, from burial Nº1 of Nefteprovod-2, is of very good quality, and it would not be surprising if it made its way to YFull’s tree. It can be … Read the rest “Earliest (and basal) haplogroup N-L1026, from East Siberia”
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. This
