DESCRIPTION:Traits can only function together if expressed together\, but 
 the evolution of such phenotypic integration remains poorly understood. In
  this talk\, I will present our recent work on the evolutionary origin and
  geographic spread of a sexually selected syndrome in wall lizards. Climat
 ic effects on the strength of sexual selection causes a mosaic of phenotyp
 ic variation across the landscape\, and promotes asymmetric introgression 
 into a distantly related lineage. The phenotypic integration of color\, mo
 rphology\, and behavior persists throughout a hybrid zone\, pointing towar
 ds a genetic architecture with a single or few major loci. Analyses of gen
 omic data supports this hypothesis and reveals a single candidate region w
 ith striking structural variations. I discuss how this genomic architectur
 e can orchestrate the co-expression of color\, morphology\, and behavior\,
  and what it can teach us about the evolution of complex phenotypes.
