Male genitalia show patterns of divergent evolution, and sexual selection is recognised as
being responsible for this taxonomically widespread phenomenon. Much of the empirical …

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 …

A common procedure in the regression analysis of interspecies data is to first test the
independent and dependent variables X and Y for phylogenetic signal, and then use the …

1. Classic evolutionary models interpret ageing as a cost of reproduction, but evolutionary
research has thus far largely neglected the conceptual links between the evolution of ageing …

Male–female coevolution has taken different paths among closely related species, but our
understanding of the factors that govern its direction is limited. While it is clear that …

Genital coevolution between the sexes is expected to be common because of the direct
interaction between male and female genitalia during copulation. Here we review the …

In many animal groups genital structures appear to have evolved extremely rapidly,
prompting enduring interest in why this is so. Throughout this literature there remains a bias …

One of the most enigmatic observations in evolutionary biology is the evolution of
morphological or physiological traits in one sex that physically injure members of the other …

Female genitalia have been largely neglected in studies of genital evolution, perhaps due to
the long‐standing belief that they are relatively invariable and therefore taxonomically and …

Insects display a staggering diversity of mating and social behaviours. Studying these
systems provides insights into a wide range of evolutionary and behavioural questions, such …
