I just emailed this to the authors of High-resolution genomic ancestry reveals mobility in early medieval Europe, a new preprint at bioRxiv [LINK]. I appreciate that Polish population history is not the main focus of your preprint, and also that you're constrained by the lack of relevant and suitably high quality ancient genomes from East-Central and Eastern Europe. However, I must say that your| Eurogenes Blog
A new preprint at bioRxiv by Kerdoncuff et al. makes the following, somewhat surprising, claim: One of the individuals, referred to Sarazm_EN_1 (I4290) described above that was discovered with shell bangles showing affiliation with South Asia, has significant amount AHG-related ancestry, while a model without AHG-related ancestry provides the best fit for Sarazm_EN_2 (I4210) (Table S4.5).

It's always amusing to see some random Jovan or Dimitar arguing online that Slavic speakers have been in the Balkans since at least the Neolithic. Obviously, Slavic peoples only turned up in the Balkans during the early Middle Ages. It's just that their linguistic and genetic impact on the region was so profound that it may seem like they've been there forever. A new paper at Cell by Olalde et| Eurogenes Blog
The ancIBD method paper from the David Reich Lab was just published in Nature (open access here). It's a very useful effort, but the authors are still somewhat confused about the origin of the Corded Ware culture (CWC) population. From the paper (emphasis is mine): This direct evidence that most Corded Ware ancestry must have genealogical links to people associated with Yamnaya culture spanning| Eurogenes Blog
A few weeks ago bioRxiv published two preprints on the Seima-Turbino Phenomenon (see here and here). I can't say much about these manuscripts until I see the relevant ancient DNA samples, and that might take some time. However, for now, I will say that both preprints really need to emphasize the profound impact that the Sintashta-related early Indo-Iranian speakers had on the Seima-Turbino| Eurogenes Blog
When used properly, Principal Component Analysis (PCA) is an extraordinarily powerful tool and one of the best ways to study fine-scale genetic substructures within Europe. The PCA plot below is based on Global25 data and focuses on the genetic relationship between Wielbark Goths and Medieval Poles, including from the Viking Age, in the context of present-day European genetic variation.

Here's an abstract of a new study from the David Reich Lab about ancient Slavs, titled "Genetic identification of Slavs in Migration Period Europe using an IBD sharing graph". Emphasis is mine: Popular methods of genetic analysis relying on allele frequencies such as PCA, ADMIXTURE and qpAdm are not suitable for distinguishing many populations that were important historical actors in the| Eurogenes Blog
I'm totally serious when I say that this video is more objective, informative and accurate than any peer-reviewed paper published to date when it comes to the genetic origins of the Khvalynsk people. However, that's not to say it's perfect. I think it misses some important details. See here...

I've now had the chance to read and digest the following two papers in Science about the origin of Indo-European languages: Language trees with sampled ancestors support a hybrid model for the origin of Indo-European languages, Heggarty et al.

I've started analyzing the Identity-by-Descent (IBD) data from the recent Ringbauer et al. preprint (see here). Unfortunately, it'll take me a few weeks to do this properly, so I won't be able to write anything detailed on the topic for a while. Meantime, this is the comment that I left for the authors at bioRxiv (at this time it's still being approved, but it should appear there within a day or| Eurogenes Blog
Lazaridis, Alpaslan-Roodenberg et al. recently claimed that the Yamnaya people of the Pontic-Caspian (PC) steppe carried "substantial" ancestry from what is now Armenia or surrounds. However, this claim is essentially false. Only one individual associated with the Yamnaya culture shows an unambiguous signal of such ancestry. This is a female usually labeled Ukraine_Yamnaya_Ozera_o:I1917. The "| Eurogenes Blog
Almost a decade ago scientists at the David Reich Lab extracted DNA from the remains of three men from the Khvalynsk II cemetery at the northern end of the Pontic-Caspian (PC) steppe. These Eneolithic Eastern Europeans showed significant genetic heterogeneity, with highly variable levels of Eastern Hunter-Gatherer (EHG) and Near Eastern-related ancestry components. As a result, the people at| Eurogenes Blog
Kevin Brook, who occasionally comments on this blog, has published a peer-reviewed book titled The Maternal Genetic Lineages of Ashkenazic Jews. The book focuses on 129 mitochondrial (mtDNA) haplogroups that are found in present-day Ashkenazic Jews, and reveals that these lineages can be traced back to a wide range of places, such as Israel, Italy, Poland, Germany, North Africa, and China.

This is about the only successful qpAdm model that I can find for the pair of Early Bronze Age (EBA) females from Yassitepe, Turkey, using a decent set of outgroups and markers. I wouldn't take it too literally, but it does suggest a potentially significant level of European ancestry, including some steppe ancestry, in these Yassitepe individuals.
