It is written with a clear style which should invite interest from a wide range of social scientists. The relatedness of humans and non-human primates that was usually considered in its genetic forms is followed through into the complex social tactics of monkeys and apes. The focus of the book was on the latest research as it had developed out of earlier classic studies. The wave of researchers working on social topics at the time is especially emphasized. This book will be of particular interest to primatologists, ethologists, anthropologists, zoologists, social psychologists, and students of social cognition and social interaction. For students, the appendices provide useful information on the variety of social structures of Old World and New World monkeys and apes.
