Sexual selection drives asymmetric introgression in wall lizards

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.
