As I said 6 months ago, 2019 is a tough year to write a blog, because this was going to be a complex regional election year and therefore a time of political promises, hence tenure offers too. Now the preliminary offers have been made, elections have passed, but the timing has slightly shifted toward 2020. So I may have the time, but not really any benefit of dedicating too much effort to the blog, and a lot of potential benefit of dedicating any time to evaluable scientific work.
On the other hand, I saw some potential benefit for … Read the rest “A Song of Sheep and Horses, revised edition, now available as printed books”
I said I would write a post about topo-hydronymy in Europe and Iberia based on the most recent research, but it seems we can still enjoy some more discussions about the famous Vasconic Beakers, by people longing for days of yore. I don’t want to spoil that fun with actual linguistic data (which I already summarized) so let’s review in the meantime one of the main Uralic-Indo-European interaction zones: Scandinavia.
One of the many eye-catching interpretations – and one of the few interesting ones – that could be found in the relatively recent article Talking … Read the rest “Pre-Germanic and Pre-Balto-Finnic shared vocabulary from Pitted Ware seal hunters”
Sorry for the last weeks of silence, I have been rather busy lately. I am having more projects going on, and (because of that) I also wanted to finish a project I have been working on for many months already.
I have therefore decided to publish a provisional version of the text, in the hope that it will be useful in the following months, when I won’t be able to update it as often as I would like to:

This is the second of four posts on the Corded Ware—Uralic identification:
I read from time to time that “we have not sampled Uralic speakers yet”, and “we are waiting to see when Uralic-speaking peoples are sampled”. Are we, though?
Proto-language homelands are based on linguistic data, such as guesstimates for dialectal evolution, loanwords and phonetic changes for language contacts, toponymy … Read the rest “Corded Ware—Uralic (II): Finno-Permic and the expansion of N-L392/Siberian ancestry”
Interesting information from ISBA 8 sesions today, as seen on Twitter (see programme in PDF, and sessions from the 19th and the 20th september).
Official abstracts are listed first (emphasis mine), then reports and images and/or link to tweets. Here is the list for quick access:

Open access Ancient genome-wide analyses infer kinship structure in an Early Medieval Alemannic graveyard, by O’Sullivan et al., Science (2018) 4(9):eaao1262
The Alemanni were a confederation of Germanic tribes that inhabited the eastern Upper Rhine basin and surrounding region (Fig. 1) (1). Roman ethnographers mentioned the Alemanni, but historical records from the 3rd to the 6th century CE contain no regular description of these tribes (2). The upheaval that occurred during the European Migration Period (Völkerwanderung) partly explains the interchangeability of nomenclature with the contemporaneous Suebi people of the same region and periods of geographic discontinuity

Good timing for the publication of two interesting papers, that a lot of people should read very carefully:
Open access A tutorial on how not to over-interpret STRUCTURE and ADMIXTURE bar plots, by Daniel J. Lawson, Lucy van Dorp & Daniel Falush, Nature Communications (2018).
Interesting excerpts (emphasis mine):
Experienced researchers, particularly those interested in population structure and historical inference, typically present STRUCTURE results alongside other methods that make different modelling assumptions. These include TreeMix, ADMIXTUREGRAPH, fineSTRUCTURE, GLOBETROTTER, f3 and D statistics, amongst many others. These models can be used both to probe whether assumptions of the model

New bioRxiv preprint A genetic perspective on Longobard-Era migrations, by Vai et al. (2018).
Interesting excerpts (emphasis mine):
In this study we sequenced complete mitochondrial genomes from nine early-medieval cemeteries located in the Czech Republic, Hungary and Italy, for a total of 87 individuals. In some of these cemeteries, a portion of the individuals are buried with cultural markers in these areas traditionally associated with the Longobard culture (hereby we refer to these cemeteries as LC), as opposed to burial communities in which no artifacts or rituals associated by archaeologists to Longobard culture have been found in any graves.
