Primatology comes of age: 2002 AAPA Luncheon Address.

The growth of primate field studies has occurred along multiple dimensions representing expansion in the number of species studied, comparative studies of different populations of the same species, and populations and groups studied over time. The accumulation of data on a broader taxonomic diversity of primates has contributed to advances in the use of comparative methods for gaining insights into interspecific variation in behavior patterns, but the incorporation of intraspecific variation into comparative models of behavior has lagged behind. This delay can be attributed, in part, to the slow rate at which the interacting effects of life history and demography on behavior emerge in slow-growing, long-lived primates. It may also reflect the anthropocentric foundation of field primatology, which historically focused on interspecific comparisons with humans instead of interpopulation variation among primates. Conservation concerns have stimulated new thinking about the importance of populations and the range of behavioral variation that populations maintain. The integration of intra- and interspecific behavioral variation will distinguish the next generation of comparative models in primatology, and set a new agenda as field primatology comes of age.
