Geometric morphometrics—a set of methods for the statistical analysis of shape once
saluted as a revolutionary advancement in the analysis of morphology—is now mature and …

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

The Darwin–Bateman paradigm recognizes competition among males for access to multiple
mates as the main driver of sexual selection. Increasingly, however, females are also being …

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 …

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 …

Background Following recent advances in bioimaging, high-resolution 3D models of
biological structures are now generated rapidly and at low-cost. To use this data to address …

Male reproductive success is influenced by competitive interactions during precopulatory
and postcopulatory selective episodes. Consequently, males can gain reproductive …

Male genitalia exhibit patterns of divergent evolution driven by sexual selection. In contrast,
for many taxonomic groups, female genitalia are relatively uniform and their patterns of …

In contrast to male genitalia that typically exhibit patterns of rapid and divergent evolution
among internally fertilizing animals, female genitalia have been less well studied and are …
