During the latter half of the last century, evidence of reproductive competition between males
and male selection by females led to the development of a stereotypical view of sex …

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
success of that sex as a result of differential access to mates or fertilisations. The …

Although competition between females is one of the cornerstones of the theory of natural
selection, most studies of reproductive competition have focussed principally on mating …

Animals living in groups will profit most from sociality if they coordinate the timing and nature
of their activities. Self-organizing mechanisms can underlie coordination in large animal …

Primates are noted for their varied and complex pelage and bare skin coloration but the
significance of this diverse coloration remains opaque. Using new updated information …

Multimale–multifemale groups, where both sexes mate promiscuously and the operational
sex ratio is male biased, represent a classical mammalian society. Theory predicts low …

The causes and consequences of being in a particular dominance position have been
illuminated in various animal species, and new methods to assess dominance relationships …

Social learning can play a critical role in the reproduction and survival of social animals.
Individual differences in the propensity for social learning are therefore likely to have …

The second important evolutionary insight is that the greater investment by females in each
reproductive event usually takes females out of the reproductive population for longer …
