- Reposted by Chiara BarbieriWe have a few remaining seats left in the “Programming for Evolutionary Biologists” course - 10th edition, Berlin, Feb 17 to Mar 6 evop.bioinf.uni-leipzig.de A highly motivated and experienced team is waiting for you with an updated curriculum!
- "DNA tells story of language Methodologically, the study’s move is elegant. Historical documents can be rich but patchy, and for many regions and eras they simply don’t exist. Genes keep a different kind of ledger. When populations intermix, they leave an imprint that persists for thousands years."
- A very special paper where we did something NEW! 🔥combining a large genetic dataset 🧬, a large linguistic dataset 💬, and Bayesian multilevel logistic regressions 📈, counting the effects of areal contact (geographic constrains) 🌎. Genetic admixture explains higher levels of linguistic exchanges...
- Our paper is out! We linked genetic and linguistic data to study how contact changes language and found consistent patterns of borrowing across contact situations @balthasarbickel.bsky.social @chiarabarbieri.bsky.social @nccrlanguage.bsky.social @isle-uzh.bsky.social doi.org/10.1126/sciadv.adv7521
- ... as we are using genetics as an independent source to spot instances of contact between populations that speak unrelated languages. The ADMIXTURE runs from K=2 to K=30 on a global set of 4768 individuals in 558 populations associated with 373 languages is already an interesting result itself!
- Some features are preferentially borrowed between languages under contact, while a minority of features preferentially diverge. In contact within the same macro geographic region, prosody is a feature that preferentially diverges: a signal of distinction and identity marking!
- our study has implication to understand language evolution, language acquisition, social dynamics in cultural evolution, and how in time of globalization extreme contact is eroding deeper layers of linguistic diversity. thx to @nccrlanguage.bsky.social
- Reposted by Chiara Barbieri📰When populations meet, they exchange genes, but also language features. According to a new study by NCCR researchers, contact between human populations increases the resemblance between their languages to similar extents all over the world, but differently. evolvinglanguage.ch/capturing-la...
- New paper! ⚡ With Gabriel Aguirre and Marcelo Sánchez, looking at patterns of blowgun types and use across societies of the world. We find areal patterns, similarities mediated by cultural connections, and specific types characterizing distinct branches of the Austronesian language tree. 🎯

- New paper on the genetic legacy of living inhabitants of the Northern Coast of Peru. With Ricardo Fujita and José Sandoval of USMP Lima,master student Lea Huber,@epifaniaarango.bsky.social,@kkshimizu1.bsky.social Genetic lineages characteristic of the region link to aDNA from local archaeo sites...
- ...while other genetic profiles are related to Peruvian and Ecuadorian groups. We also find a local signal of structure that match with linguistic and cultural boundaries already present at the time of the Moche empire. We worked with Matthias Urban for linguistic contextualization...
- ... and with an international team of geneticists to reconstruct the mtDNA and Y chromosome genealogies. Uniparental markers are still very useful, as ancient and modern comparative data for the region is available...

- Feels like time travelling. Science and art reconstruct the life of our ancestors
- New volume on the interface between languages, human history, anthropology, archaeology and (a bit of) genetics, curated by M. Robbeets and M. Hudson. A very rich table of content for everyone interested in these multidisciplinary studies of the human past. I contributed two chapters:
- Here with Paul Widmer we provide a review of how modern and ancient DNA data have been expanding our knowledge of human history, and which demographic scenarios can be meaningful for linguistic reconstructions. I recommend the read to linguists that want to expand on the field of genetics!
- Here with Matthias Urban and Kurt Rademaker we cover the major linguistic, archaeological and genetic structural patterns of the Andes, focusing on interesting case studies where the disciplines tell us a coherent history.
- Reposted by Chiara BarbieriOur new paper is out in @science.org! By exploring the rich genetic diversity of Brazil, we show how fine-scale genomic analyses reveal that this diversity, rooted in Indigenous ancestry and centuries of complex demographic history, plays a key role in population health.
- SIBE Summer School: evolution of populations at a scale. Ferrara 7-11 September. Application deadline 11 May. Travel grants available. A very nice format to learn about population genetics, conservation genomics, grant application, outreach, and networking. See you in Ferrara!
