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 …

Successful reconstruction of any aspect of human evolution ideally requires broad‐based
comparisons with other primates, as recognition of general principles provides a more …

There is particular interest in understanding socioeconomic and ethnic variability in health
status. The developmental origins of disease hypothesis emphasize the importance of …

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 …

Cooperative behavior is a hallmark of the primate order. Cooperation is therefore an area of
intensive theoretical research in biology, anthropology, political sciences and economics, as …

Chimpanzees are important referential models for the study of life history in hominin
evolution. Age at sexual maturity and first reproduction are key life history milestones that …

We present body mass (N= 419) and crown‐rump length (CRL, N= 210) measurements from
38 male and 49 female mandrills born into a semifree‐ranging colony in order to describe …

In most mammalian species, females regularly interact with kin, which is expected to reduce
aggressive competitive behaviour among females. It may thus be difficult to understand why …

We investigated relationships between fecal androgen concentrations, facial coloration and
behaviour in semi-free-ranging male mandrills. We found that fecal androgen levels were …

The timing of early life‐history events, such as sexual maturation and first reproduction, can
greatly influence variation in individual fitness. In this study, we analysed possible sources of …
