PRIMATE ORIGINS: ADAPTATIONS
AND EVOLUTION
DEVELOPMENTS IN PRIMATOLOGY: PROGRESS AND PROSPECTS
Series Editor: Russell H. Tuttle, University of Chicago, Chicago, Illinois
This peer-reviewed book series melds the facts of organic diversity with the continuity of
the evolutionary process. The volumes in this series exemplify the diversity of theoretical
perspectives and methodological approaches currently employed by primatologists and
physical anthropologists. Specific coverage includes: primate behavior in natural habitats
and captive settings; primate ecology and conservation; functional morphology and
developmental biology of primates; primate systematics; genetic and phenotypic
differences among living primates; and paleoprimatology.
