Since Darwin's conception of sexual selection theory, scientists have struggled to identify the
evolutionary forces underlying the pervasive differences between male and female …

Following Darwin's original insights regarding sexual selection, studies of intrasexual
competition have mainly focused on male competition for mates; by contrast, female …

For sexual selection to act on a given sex, there must exist variation in the reproductive

“Beliefs about men and women are as old as humanity itself, but Fine's funny, spiky book

We give a historic overview and critical perspective of polyandry in the context of sexual
selection. Early approaches tended to obfuscate the fact that the total matings (copulations) …

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 …

In 1948, Angus J. Bateman reported a stronger relationship between mating and
reproductive success in male fruit flies compared with females, and concluded that selection …

Among primates, intense paternal care is manifested in only a few distantly related species,
including humans. Thus, neither purely phylogenetic nor socioecological hypotheses can …

This paper traces the development of our understanding of the development of different
approaches to estimating the strength of reproductive competition and sexual selection in …
