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

How many chromosomes can an animal have? In our paper out now in @currentbiology.bsky.social we show that the Atlas blue butterfly has 229 chromosome pairs- the highest in diploid Metazoa! These arose by rapid autosome fragmentation while sex chromosomes stayed intact. www.cell.com/current-biol...

Still possible to apply to this #post-doc position at CESAB #Montpellier. Application closing date: September 15th 2025 (12:00 PM CET) How taking intraspecific diversity and evolutionary processes into account in translocation-based programs. Please share widely #PopGen #NbS #Biodiversity

I'm hiring a postdoc... By combining samples that are more than a million years old with the short generation time of small rodents, we hope to gain a unique window into evolution unfolding across millions of generations!

🚨 Hiring! We are looking for a postdoctoral researcher with expertise in computational fluid dynamics and structural simulations to investigate biomechanics and mechanosensory feedback in insect flight. Extreme agility ✔️ Morphological computing ✔️ Meshes! ✔️ jobs.rvc.ac.uk/vacancy.aspx...

Our false head work is out! By analysing ~1000 #butterflies, we found many traits at posterior end of hindwings evolved correlatedly, likely forming a trait complex w/adaptive function to dupe predators into thinking these traits together are actual head!! royalsocietypublishing.org/doi/10.1098/...

Why do treehoppers look so weird?! Our latest paper, out this week in @pnas.org, suggests a perhaps unexpected reason - static electricity ⚡ We show that treehoppers can detect the electrostatic cues of predators and that their crazy shapes may boost their electrosensitivity! doi.org/10.1073/pnas...
