Twenty years ago, a seminal paper summarized the role of sexual selection in speciation as
the coordinated evolution of (male) courtship signals and (female) preferences leading to …

Support for the role of sexual selection in speciation has grown over the last 30 years. Work
in this area, however, has largely focused on a single dominant question: when and how do …

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 …

Hybrid zones provide insights into the evolution of reproductive isolation. Sexual selection
can contribute to the evolution of reproductive barriers, but it remains poorly understood how …

Competition for mates can play a critical role in determining reproductive success, sha**
phenotypic variation within populations, and influencing divergence. Yet, studies of the role …

Research on sexual selection and hybridization has focused on female mate choice and
male–male competition. While the evolutionary outcomes of interspecific female preference …

Strongly selected characters can be transferred from one lineage to another with limited
genetic exchange, resulting in asymmetric introgression and a mosaic genome in the …

The common practice of using subspecies as conservation targets raises the question of
whether efforts are focused on preserving conspicuous components of the species' …

Divergence in sexually selected traits in allopatry should affect the degree and direction of
hybridization. However, few studies have established the causes and targets of sexual …

Colour polymorphism occurs when two or more genetically-based colour morphs
permanently coexist within an interbreeding population. Colouration is usually associated to …
