Definitive, broad-ranging reference work on Old World monkeys (Cercopithecoids).Old World monkeys are the most successful and diverse group of nonhuman primates living today. They can teach us much about evolutionary processes and the principles of ecology, and are among our closest living relatives. This volume presents a broad account of their biology including molecular, behavioral and morphological approaches to phylogeny, population structure, fossil history, functional morphology, ecology, social behavior and conservation. It will be the definitive reference for this group for professionals, graduate students and senior undergraduates in primatology, animal behavior, paleontology, morphology, systematics and physical anthropology.Old World monkeys are the most successful and diverse group of nonhuman primates living today.

Among our closest living relatives, they have much to teach us about the processes of evolution and the principles of ecology. This volume presents a broad, technical account of cercopithecoid biology including molecular, behavioral, and morphological approaches to phylogeny, population structure, allometry, fossil history, functional morphology, ecology, cognitive capabilities, social behavior, and colÓ%
