Sexual selection is a key component of evolutionary biology. However, from the very
formulation of sexual selection by Darwin, the nature and extent of sexual selection have …

The distinct reproductive roles of males and females, which for many years were
characterised in terms of competitive males and choosy females, have remained a central …

Ornaments, weapons and aggressive behaviours may evolve in female animals by mate
choice and intrasexual competition for mating opportunities—the standard forms of sexual …

Conventional sex roles imply caring females and competitive males. The evolution of sex
role divergence is widely attributed to anisogamy initiating a self‐reinforcing process. The …

Sperm are produced in astronomical numbers compared with eggs, and there is good
evidence that sperm competition is the force behind the evolution of many tiny sperm …

Research on sexual selection shows that the evolution of secondary sexual characters in
males and the distribution of sex differences are more complex than was initially suggested …

Mate choice by males has been recognized at least since Darwin's time, but its phylogenetic
distribution and effect on the evolution of female phenotypes remain poorly known …

Models of Adaptive Behaviour sets out a framework for adaptive explanations of behaviour,
and applies this to give analyses of a range of biological issues such as energetic gain …

Sexual conflict is a conflict between the evolutionary interests of individuals of the two sexes.
The sexes can have different trait optima but this need not imply conflict if their optima can …
