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

Rare in mammals but more common in primates, there remains a considerable controversy
concerning whether primate species traditionally described as monogamous actually …

Male mammals often kill conspecific offspring. The benefits of such infanticide to males, and
its costs to females, probably vary across mammalian social and mating systems. We used …

Humans stand out among the apes by having both an extremely large brain and a relatively
high reproductive output, which has been proposed to be a consequence of cooperative …

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 …

The evolution of parental care is beneficial if it facilitates offspring performance traits that are
ultimately tied to offspring fitness. While this may seem self‐evident, the benefits of parental …

Current discussions in evolutionary ecology and conservation genetics focus on the relative
importance of using selective neutral markers or markers of coding genes to identify …

Male care has energetic and opportunity costs, and is more likely to evolve when males gain
greater certainty of paternity or when future mating opportunities are scarce. However, little …

Understanding the evolution of mating systems, a central topic in evolutionary biology for
more than 50 years, requires examining the genetic consequences of mating and the …

Adult neurogenesis–the formation of new neurons in adulthood–has been shown to be
modulated by a variety of endogenous (eg, trophic factors, neurotransmitters, and …
