The role of hybridisation in facilitating macroevolutionary change

Species boundaries can remain semipermeable for prolonged periods of time. Interspecific gene flow mostly occurs between sister-species but instances of hybridization are occasionally also recorded among distantly related clades. We are interested in understanding to what extent occasional gene flow can benefit recipient populations and under what circumstances introgressed genetic variants can eventually drive evolutionary change.

To study these questions, we use whole-genome resequence or exon-capture data and focus on two different organismal groups: (i) Birds-of-Paradise and (ii) Cryptoblepharus skinks.
