Recently published paper Genomic Data from an Ancient European Battlefield Indicates On-Going Strong Selection on a Genomic Region Associated with Lactase Persistence Over the Last 3,000 Years, by Burger et al., submitted to Current Biology, available at CellPress SneakPeek.
Interesting excerpts (emphasis mine):
Tollense sample shows no structure
Multiple lines of evidence point to little or no genetic structure in the population from which the Tollense individuals were sampled. First, all individuals fall within the range of Central and northern European variation when projected onto a principle component analysis (PCA) trained on modern samples and their spread matches that

When I started ruminating in 2016 over the apparent differences between populations that kept the two-velar distinction of Indo-Tocharian, and the only two unrelated dialectal groups that showed a strong satemization trend, I believed that – much like in modern times – there would be no clear-cut division in terms of ancestry or Y-DNA haplogroups between neighbouring forest-steppe and steppe populations.
The answer to the question of interacting ethnolinguistic groups had to lie, as everything else, on the investigation of fine-scale population movements that must have put Uralic-speaking peoples as the main substratum of Balto-Slavic and Indo-Iranian.
Still, … Read the rest “RISE1.SG, R1b from Poland CWC, a likely mislabelled Balto-Slav”
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:

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”
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.

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

In my recent post about the origin and expansion of haplogroup R1b-L51, Chetan made an interesting comment on the origin and expansion of R1a-Z645. Since this haplogroup is also relevant for European history and dialectal North-West Indo-European and Indo-Iranian expansion, I feel compelled to do a similar post, although the picture right now is more blurry than that of R1b-L51.
I find it interesting that many geneticists would question the simplistic approach to the Out of Africa model as it is often enunciated, but they would at the same time consider the current simplistic model of Yamna expansion… Read the rest “On the origin and spread of haplogroup R1a-Z645 from eastern Europe”
Open Access Mitochondrial genomes reveal an east to west cline of steppe ancestry in Corded Ware populations, by Juras et al., Scientific Reports (2018) 8:11603.
Interesting excerpts (emphasis mine, references have been deleted for clarity):
Ancient DNA was extracted from the Corded Ware culture individuals excavated in southeastern Poland (N = 12) and Moravia (N = 3). Late Eneolithic (N = 5) and Bronze Age human remains (N = 25) originated from western Ukraine and came from the Yampil barrow cemetery complex located in the north–western region of the Black Sea. Bronze Age individuals were associated with different archaeological
