Many hypotheses have been proposed to explain why male intromittent genitalia
consistently tend to diverge more rapidly than other body traits of the same individuals in a …

In one of his few major oversights, Darwin failed to appreciate that male–male competition
and sexual selection can continue even after copulation has begun. The postcopulatory …

The first comprehensive genus-level phylogeny of the subfamily Sarcophaginae is
presented. A morphology-based phylogenetic analysis using parsimony is performed with …

Background The species-specificity of male genitalia has been well documented in many
insect groups and sexual selection has been proposed as the evolutionary force driving the …

The evolutionary forces responsible for the evolution of animal genitalia have a long history
of controversy. Why the special interest in genitalia? In addition to the intrinsic interest of …

Few disciplines in science are as obsessed with 'going digital'as taxonomy. This is not
surprising given that 'taxonomy is made for the web: it is an information-rich subject, often …

Sexual selection can displace traits acting as ornaments or armaments from their viability
optimum in one sex, ultimately giving rise to sexual dimorphism. The degree of dimorphism …

Our understanding of how fast mating behaviour evolves in insects is rather poor due to a
lack of comparative studies among insect groups for which phylogenetic relationships are …

The Sepsidae is, with approximately 300 described species, a relatively small family of
cyclorrhaphan flies whose behaviour, morphology, and development have been extensively …

Sexual size dimorphism (SSD) varies widely across and within species. The differential
equilibrium model of SSD explains dimorphism as the evolutionary outcome of consistent …
