Abstract
Data on captive longevity in 587 mammalian species were analyzed in order to evaluate primate longevity in the context of general mammalian life history patterns. Contrary to some recurrent claims in the literature, we found that 1) primates are not the longest-lived mammalian order, either by absolute longevity, longevity corrected for body size, or metabolic expenditure per lifetime; 2) although relative brain size is highly correlated with longevity in primates, this is an aberrant trend for mammals in general, and other body organs account for an even greater amount of variation in longevity; and 3) there has been no progressive evolution of increased longevity among the primate superfamilies. The exceptional magnitude of primate longevity may, in keeping with evolutionary senescence theory, be due to an evolutionary history of low vulnerability to environmentally imposed death due to their body size, arboreal habit, and propensity to live in social groups.
