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...

An empirically-based scenario for the evolution of cultural transmission in the human lineage during the last 3.3 million years Humans accumulate an ever-growing body of knowledge that far exceeds the capacity of any single individual or generation. Social learning and transmission are essential for this process. However, how ...

Discover our results of the largest ancient DNA study ever conducted on a single burial site: 400 skeletons from the Belgian city Sint-Truiden (8th–18th century). A unique glimpse into 1000 years of genetic history. (1/9) @kuleuvenuniversity.bsky.social

Genetic ancestry and nucleotide diversity. Colors represent genetic ancestries estimated by whole-genome sequencing data of contemporary human populations. Countries having no data remained empty. Circle size indicates the average nucleotide diversity of each population.

Fantastic paper in @science.org today revealing:
1. strong selection for cold tolerance in Beringia
2. gene-flow across the strait around 5ky
3. diversification of S. American lineages into 4 groups ~ 14k-10ky
4. followed by population crash of >40-80%

Wat verhalen die de wereld over reizen over de mensheid onthullen In mythen overal ter wereld zitten elementen die al met de mensheid meereizen zo lang die bestaat. Dat blijkt als je culturele en genetische informatie combineert.

The Coming Out of a Transgender Scientist "I know that I am making the right decision because whenever I think about changing my gender role, I am flooded with feelings of relief."

We're disappointed to see Ben Barres's powerful book "The Autobiography of a Transgender Scientist" among the ~400 titles removed from the Naval Academy Library. Needless to say, we're proud to have published his book and will keep it — and his memory — alive.

A geographic history of human genetic ancestry Describing the distribution of genetic variation across individuals is a fundamental goal of population genetics. We present a method that capitalizes on the rich genealogical information encoded in g...

Really excited to see this work, led by Mike Grundler, published! It's a new method for inferring the geographic locations of shared genetic ancestors. In the paper, we and use it to infer the geographic history of human genetic ancestry

Our papers, out today in @nature.com, show how ancient DNA from the Eneolithic and Bronze Age steppe points to a North Pontic origin of the Indo-European language family and a Caucasus-Lower Volga (CLV) origin of Indo-Anatolian (inclusive of the now extinct Anatolian languages). 1/

Thank you, Felix! It's been wonderful meeting you and I sincerely look forward to the next time.
Lots of inspiring chats and prospects!

thank you so much, Sergi! It was really nice meeting you there, I hope we'll see each other again in the future!

Very interesting research on the relationship of cultural and genetic diffusion. Hélios (@heliosdlbs.bsky.social) gave an excellent presentation @icarehb.bsky.social yesterday. I look forward to the final publication.
