Essays on Human, Primate, and Mammal Evolution
This volume, published in honor of the occasion of David Pilbeam's 65th birthday, covers major topics in human, primate, and mammalian evolution, mostly from the Miocene to the present. The papers emphasize novel interpretations of several key areas of longstanding interest and importance, including Miocene biogeography and hominoid evolution, the origins of hominids, and new interpretations of the hominid fossil record.
In terms of content, most of the papers tackle key issues in the evolution of hominoids and hominids in terms of systematic paleoenvironmental and behavioral questions. More broadly, however, the papers explore the epistemological problems of how one interprets the past from the available data.

Abstract

1. Lemurs (Lemur catta) and six groups of monkeys - three groups of Old World and three of New World monkeys were compared by means of gross observations in laboratory cages. 2. The profile of scores for any one animal was unambiguously diagnostic of its species. 3. Rhesus and apella monkeys specialized in manipulating objects, stumptail monkeys in social grooming, squirrel monkeys in self manipulation and woolly monkeys in vocalizing. 4. Lemurs were not as socially oriented as monkeys and spent most of their time in visual survey or looking at social objects. 5. Results were discussed in terms of implications for laboratory studies that are based largely on one nonhuman primate (Macaca mulata).
