"Origin and introgressive spread of a sexually selected syndrome in a Mediterranean wall lizard"
Hôte : Arnaud Badiane
The joint expression of particular colors, morphologies, and behaviors is a common feature of adaptation, but the genetic basis for such ‘phenotypic syndromes’ remains poorly understood. In this talk I will present how we have traced the origin and rapid introgressive spread of a sexually selected syndrome in common wall lizards. By capitalizing on the adaptive introgression of the syndrome into a distantly related lineage, we were able to identify features of the developmental and genetic architecture that contribute to maintaining trait integration. I will discuss how these insights shed light on patterns of repeated evolution in Mediterranean wall lizards.
