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”
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”
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:

I have recently written about the spread of Pre-Yamnaya or Yamnaya ancestry and Corded Ware-related ancestry throughout Eurasia, using exclusively analyses published by professional geneticists, and filling in the gaps and contradictory data with the most reasonable interpretations. I did so consciously, to avoid any suspicion that I was interspersing my own data or cherry picking results.
Now I’m finished recapitulating the known public data, and the only way forward is the assessment of these populations using the available datasets and free tools.
Understanding the complexities of qpAdm is fairly difficult without a proper genetic and statistical background, which I … Read the rest “Bell Beakers and Mycenaeans from Yamnaya; Corded Ware from the forest steppe”
Open access Unraveling ancestry, kinship, and violence in a Late Neolithic mass grave, by Schroeder et al. PNAS (2019).
Interesting excerpts of the paper and supplementary materials, about the Złota group variant of Globular Amphora (emphasis mine):
A special case is the so-called Złota group, which emerged around 2,900 BCE in the northern part of the Małopolska Upland and existed until 2,600-2,500 BCE. Originally defined as a separate archaeological “culture” (15), this group is mainly defined by the rather local introduction of a distinct form of burial in the area mentioned. Distinct Złota settlements have not yet been identified.

This is mainly a reread of from Book Two: A Game of Clans of the series A Song of Sheep and Horses: chapters iii.5. Early Indo-Europeans and Uralians, iv.3. Early Uralians, v.6. Late Uralians and vi.3. Disintegrating Uralians.
While the true source of R1a-M417 – the main haplogroup eventually associated with Corded Ware, and thus Uralic speakers – is still not known with precision, due to the lack of R1a-M198 in ancient samples, we already know that the Pontic-Caspian steppes were probably not it.
We have many samples from the north Pontic area since … Read the rest “ASoSaH Reread (II): Y-DNA haplogroups among Uralians (apart from R1a-M417)”
Interesting report by Bernard Sécher on Anthrogenica, about the Ph.D. thesis of Samantha Brunel from Institut Jacques Monod, Paris, Paléogénomique des dynamiques des populations humaines sur le territoire Français entre 7000 et 2000 (2018).
NOTE. You can visit Bernard Sécher’s blog on genetic genealogy.
A summary from user Jool, who was there, translated into English by Sécher (slight changes to translation, and emphasis mine):
They have a good hundred samples from the North, Alsace and the Mediterranean coast, from the Mesolithic to the Iron Age.
There is no major surprise compared to the rest of Europe. On the PCA

Open access A genomic Neolithic time transect of hunter-farmer admixture in central Poland, by Fernandes et al. Scientific Reports (2018).
Interesting excerpts (emphasis mine, stylistic changes):
Most mtDNA lineages found are characteristic of the early Neolithic farmers in south-eastern and central Europe of the Starčevo-Kőrös-Criş and LBK cultures. Haplogroups N1a, T2, J, K, and V, which are found in the Neolithic BKG, TRB, GAC and Early Bronze Age samples, are part of the mitochondrial ‘Neolithic package’ (which also includes haplogroups HV, V, and W) that was introduced to Europe with farmers migrating from Anatolia at the onset of the

This is the first of four posts on the Corded Ware—Uralic identification:
I was reading The Bronze Age Landscape in the Russian Steppes: The Samara Valley Project (2016), and I was really surprised to find the following excerpt by David W. Anthony:
The Samara Valley links the central steppes with the western steppes and is a north-south ecotone between the pastoral
