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

Genomic analyses in Drosophila do not support the classic allopatric model of speciation
Abstract. The allopatric model of speciation has dominated our understanding of speciation biology and biogeography since the Modern Synthesis. It is uncon

Genomic signatures of local adaptation across parasitised cricket populations
Host-parasite interactions are predicted to exhibit geographic heterogeneity, creating the opportunity for local adaptation. This is difficult to detect because it requires knowledge of selection pres...
