New preprint on the effect of ancient admixture / structure on genealogical trees. I introduce a new way of summarising reconstructed genealogies that captures a clear signal of ancient gene flow into the ancestors of modern humans. Feedback welcome!

New paper out in Phil. Trans. B! We set out to understand how seasonal migration evolves by combining a common garden experiment and scATAC-seq of the hypothalamus in ancestral migratory and derived resident populations of the Eurasian blackcap. 1/n

Differential epigenetic regulation underlies evolutionary transition of seasonal migration

Abstract. Seasonal migratory animals can evolve residency through adaptation. The threshold model of quantitative genetics predicts that residency evolves

New paper out: “allopatric” Drosophila species aren’t so allopatric after all. We show that most currently allopatric species pairs probably overlapped in the past and exchanged genes at levels similar to sympatric pairs. @evolletters.bsky.social doi.org/10.1093/evle... [1/6]

Genomic analyses in Drosophila do not support the classic allopatric model of speciation

Leaf? 🍃 Or katydid? 🦗 Our new @plosbiology.org paper sheds light on how these incredible mimics evolved their disguises, and what this reveals about how complex adaptations arise. We find that coordinated evolution between traits might be the answer… plos.io/4oUE741 1/n

Functional and evolutionary synergy of trait components can explain the existence of leaf masquerade in katydids

The evolution of complex adaptations often involves synergistic changes in multiple traits that lack standalone function. This study shows that leaf masquerade in katydids evolved through concurrent m...
