Examining biological diversity in an explicitly evolutionary context has been the subject of
research for several decades, yet relatively recent advances in analytical techniques and the …

For more than 70 y researchers have looked to baboons (monkeys of the genus Papio) as a
source of hypotheses about the ecology and behavior of early hominins (early human …

Anthropologists have long been interested in the behavioral ecology of nonhuman primates
living in savannas given what we know of early hominin environments. As expected …

This book describes one of our closest relatives, the orangutan, and the only extant great
ape in Asia. It is increasingly clear that orangutan populations show extensive variation in …

The baboons (Papio sp.) exhibit marked interspecies variation in social behavior. The thesis
presented here argues, first, that male philopatry is a crucial factor, arguably the crucial …

The extent of diversity within closely related taxa may be a function of their shared
evolutionary history or of selective forces causing adaptive changes. Examining variation …

It has been shown that differences in resource density and nutrient supply affect variation in
ranging patterns, habitat use, and sociality. Among nonhuman primates, chimpanzees (Pan …

Common baboons (Papio), gelada baboons (Theropithecus) and baboon–mangabeys
(Lophocebus) are closely related African papionin monkeys. In 2005, the species …

Traditional neo-Darwinism ascribes geographical variation in morphology or in behaviour to
varying selection on local genotypes. However, mobile and long-lived organisms cannot …

Previous research has shown that both environmental and historical factors influence the
taxonomic structure of animal communities; yet, the relative importance of these effects is not …
