Societies develop as a result of the interactions of individuals as they compete and cooperate with one another in the evolutionary struggle to survive and reproduce successfully. Gorilla society is arranged according to these different and sometimes conflicting evolutionary goals of the sexes. In seeking to understand why gorilla society exists as it does, Alexander H. Harcourt and Kelly J. Stewart bring together extensive data on wild gorillas, collected over decades by numerous researchers working in diverse habitats across Africa, to illustrate how the social system of gorillas has evolved and endured.

Gorilla Society introduces recent theories explaining primate societies, describes gorilla life history, ecology, and social systems, and explores both sexes’ evolutionary strategies of survival and reproduction. With a focus on the future, Harcourt and Stewart conclude with suggestions for future research and conservation. An exemplary work of socioecology from two of the world’s best known gorilla biologists, Gorilla Society will be a landmark study on a par with the work of George Schaller—a synthesis of existing research on these remarkable animals and the societies in which they live.

Dawn Prince-Hughes is an extraordinary researcher. She does not experiment or measure but instead sits on a wooden bench for hours each day, watching captive gorillas through the enclosure where other visitors average five-second stops. Her patience is rewarded with astounding observations—she watches gorillas make and use tools, bury a dead crow, give birth, and comfort and care for each other.

In Gorillas among Us, Prince-Hughes has compressed years of gorilla observation into a composite diary chronicling the days of one gorilla family. She creates a blended portrait of both peoples—gorilla and human. The entries capture significant observations, which often prompt brief discussions of gorillas’ captivity, diet, communication, aesthetic preferences, social behavior, and play. Several chapters end with thought-provoking meditations on human values. The final section, “More about Gorillas,” provides a concise, accessible introduction to gorilla natural history.

This book will delight and move anyone with an interest in animals, and it also makes a significant contribution to the scarce literature on captive gorillas. Prince-Hughes's observations of tool use by gorillas will interest scientists, and even a casual reader will come away with a new sense of the power of observation. The author hopes to change the way we look at animals in the wild and in captivity, and laments that zoo visitors pause so briefly in front of the gorilla enclosure, rushing on with their assumptions unchanged, without really seeing the gorillas.

By turns opinionated and descriptive, quirky and authoritative, Prince-Hughes draws us into the family life of captive gorillas and into a consideration of our own culture. Readers will learn something new about gorillas and themselves on every page of this poignant story. The book testifies to the potential for interspecies compassion and the love that one person can find in a family of gorillas.
