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 …

Recent theoretical models predict that the evolutionary diversification of the weapons and
ornaments of pre-mating sexual selection should be influenced by trade-offs with male …

Females of many species mate with multiple males, thereby inciting competition among
ejaculates from rival males for fertilization. In response to increasing sperm competition …

ABSTRACT A central question in ecology and evolution is to understand why sexual
selection varies so much in strength across taxa; it has long been known that ecological …

How barriers to gene flow arise and are maintained are key questions in evolutionary
biology. Speciation research has mainly focused on barriers that occur either before mating …

The year 2021 marks the 150th anniversary of the publication of Charles Darwin's
extraordinary book The Descent of Man and Selection in Relation to Sex. Here, we review …

Sexual and gender minorities face considerable inequities in society, including in science. In
biology, course content provides opportunities to challenge harmful preconceptions about …

The processes underlying mate choice profoundly influence the dynamics of sexual
selection and the evolution of male sexual traits. Consistent preference for certain …

The term 'sex roles' encapsulates male–female differences in mate searching, competitive
traits that increase mating/fertilization opportunities, choosiness about mates and parental …

Sexual selection theory predicts a trade-off between premating (ornaments and armaments)
and postmating (testes and ejaculates) sexual traits, assuming that growing and maintaining …
