We are offering a fully funded two-year postdoctoral position focused on sex chromosome evolution and speciation in the *Jaera albifrons* species complex. Please find the advertisement attached. We welcome applications from interested candidates. Join us :-)

Hybridization and introgression are major evolutionary processes. Since the 1940s, the prevailing view has been that they shape plants far more than animals. In our new study (www.science.org/doi/10.1126/... ), we find the opposite: animals exchange genes more, and for longer, than plants

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 www.science.org/doi/10.1126/...

📣 The final chapter of my PhD is now out in @evolletters.bsky.social !! 📣 🦌 Using genomic and fitness data from a long-term study of red deer we investigated the interaction between inbreeding depression and the environment (ID × E) doi.org/10.1093/evle...

Do you think marine evolution #MarEvol is cool? Maybe you were at the 2018 Marine Evolution meeting in Strömstad, Sweden? And surely you'd like us to do it again and organise MarEvol2? Why not in the South of France? Then fill in this questionnaire and spread the word: framaforms.org/my-interest-...

Do mutations that drive evolution improve many traits or few? Does this change over the course of evolution? Excited to share our work in PLOS Biology exploring these questions in the first 2 adaptive steps w/ Yuping Li, @gsherloc.bsky.social, @petrovadmitri.bsky.social 🧵 doi.org/10.1371/jour...

In 2010 (SMBE Lyon) I gave a talk about the impact of GC-biased gene conversion (gBGC) on functional sequence evolution. I argued that, because gBGC promotes G and C alleles irrespective of their fitness effect, it should generate some genetic load. 1/5
