A new paper in Ecology Letters show that allopatric divergence under sexual selection can create asymmetric introgression upon secondary contact. This does not only demonstrate that sexual selection is an important driver of hybridization, but also raises interesting questions about how sexual characters can be transferred from one lineage to another.
This paper is a collaborative effort between ourselves and teams throughout Europe who have contributed samples or genetic data to allow us to test how well predictions from experimental enclosures hold up in the wild.
