Darwin's theory of sexual selection fundamentally changed how we think about sex and
evolution. The struggle over mating and fertilization is a powerful driver of diversification …

The emergence of complex social interactions is predicted to be an important selective force
in the diversification of communication systems. Parental care presents a key social context …

How novel phenotypes evolve is challenging to imagine because traits are often underlain
by numerous integrated phenotypic components, and changes to any one form can disrupt …

Behavioural traits are often noted to persist after relaxation or removal of associated
selection pressure, whereas it has been observed that morphological traits under similar …

The initial process by which novel sexual signals evolve remains unclear, because rare new
variants are susceptible to loss by drift or counterselection imposed by prevailing female …

Divergence of sexual signals between populations can lead to speciation, yet opportunities
to study the immediate aftermath of novel signal evolution are rare. The recent emergence …

Vocal communication is used across extant vertebrates, is evolutionarily ancient, and been
maintained, in many lineages. Here I review the neural circuit architectures that support …

Animals eavesdrop on signals and cues generated by prey, predators, hosts, parasites,
competing species, and conspecifics, and the conspicuousness of sexual signals makes …

The social environment is often the most dynamic and fitness-relevant environment animals
experience. Here we tested whether plasticity arising from variation in social environments …
