The adaptive value of sociality in mammalian groups
JB Silk - Philosophical Transactions of the Royal Society …, 2007 - royalsocietypublishing.org
According to behavioural ecology theory, sociality evolves when the net benefits of close
association with conspecifics exceed the costs. The nature and relative magnitude of the …

Social components of fitness in primate groups
JB Silk - Science, 2007 - science.org
There is much interest in the evolutionary forces that favored the evolution of large brains in

Strong and consistent social bonds enhance the longevity of female baboons
Longevity is a major component of variation in fitness in long-lived iteroparous species [1–4].
Among female baboons, variation in breeding lifespan accounts for approximately 50% of …

Growth rates in a wild primate population: ecological influences and maternal effects
J Altmann, SC Alberts - Behavioral ecology and sociobiology, 2005 - Springer
Growth rate is a life-history trait often linked to various fitness components, including
