Judged by population size and distribution, homo sapiens are clearly the most successful primates. A close second, however, would be rhesus macaques, who have adapted to—and thrived in—such diverse environments as mountain forests, dry grasslands, and urban sprawl. Scientists have spent countless hours studying these opportunistic monkeys, but rhesus macaques have long been overshadowed in the public eye by the great apes, who, because of their greater intelligence, are naturally assumed to have more to teach us, both about other primates and about humans as well. Dario Maestripieri thinks it is high time we shelve that misperception, and with Macachiavellian Intelligence he gives rhesus macaques their rightful turn in the spotlight. The product of more than twenty years studying these fascinating creatures, Macachiavellian Intelligence caricatures a society that is as much human as monkey, with hierarchies and power struggles that would impress Machiavelli himself. High-status macaques, for instance, maintain their rank through deft uses of violence and manipulation, while altruism is almost unknown and relationships are perpetually subject to the cruel laws of the market. Throughout this eye-opening account, Maestripieri weds his thorough knowledge of macaque behavior to his abiding fascination with human society and motivations. The result is a book unlike any other, one that draws on economics as much as evolutionary biology, politics as much as primatology. Rife with unexpected connections and peppered with fascinating anecdotes, Macachiavellian Intelligence has as much to teach us about humans as it does about macaques, presenting a wry, rational, and wholly surprising view of our humanity as seen through the monkey in the mirror.

Evolutionary maternal effects occur whenever a mother’s phenotypic traits directly affect her offspring’s phenotype, independent of the offspring’s genotype. Some of the phenotypic traits that result in maternal effects have a genetic basis, whereas others are environmentally determined. For example, the size of a litter produced by a mammalian mother—a trait with a strong genetic basis—can affect the growth rate of her offspring, while a mother’s dominance rank—an environmentally determined trait—can affect the dominance rank of her offspring. The first volume published on the subject in more than a decade, Maternal Effects in Mammals reflects advances in genomic, ecological, and behavioral research, as well new understandings of the evolutionary interplay between mothers and their offspring. Dario Maestripieri and Jill M. Mateo bring together a learned group of contributors to synthesize the vast literature on a range of species, highlight evolutionary processes that were previously overlooked, and propose new avenues of research. Maternal Effects in Mammals will serve as the most comprehensive compendium on and stimulus for interdisciplinary treatments of mammalian maternal effects.

Ordinary people can perform acts of astonishing selflessness, sometimes even putting their lives on the line. A pregnant woman saw a dorsal fin and blood in the water—and dove right in to pull her wounded husband to safety. Remarkably, some even leap into action to save complete strangers: one New York man jumped onto the subway tracks to rescue a boy who had fallen into the path of an oncoming train. Such behavior is not uniquely human. Researchers have found that mother rodents are highly motivated to bring newborn pups—not just their own—back to safety. What do these stories have in common, and what do they reveal about the instinct to protect others? In The Altruistic Urge, Stephanie D. Preston explores how and why we developed a surprisingly powerful drive to help the vulnerable. She argues that the neural and psychological mechanisms that evolved to safeguard offspring also motivate people to save strangers in need of immediate aid. Eye-catching dramatic rescues bear a striking similarity to how other mammals retrieve their young and help explain more mundane forms of support like donating money. Merging extensive interdisciplinary research that spans psychology, neuroscience, neurobiology, and evolutionary biology, Preston develops a groundbreaking model of altruistic responses. Her theory accounts for extraordinary feats of bravery, all-too-common apathy, and everything in between—and it can also be deployed to craft more effective appeals to assist those in need.

This book uses evolutionary psychology as a lens to explain religious violence and oppression. The author, a clinical psychologist, examines religious scriptures, rituals, and canon law, highlighting the many ways in which our evolutionary legacy has shaped the development of religion and continues to profoundly influence its expression. The book focuses on the image of God as the dominant male in Judaism, Christianity, and Islam. This traditional God concept is seen as a reflection of the “dominant ape” paradigm so evident in the hierarchical social structures of primates, with whom we have a strong genetic connection. The author describes the main features of male-dominated primate social hierarchies— specifically, the role of the alpha male as the protector of the group; his sexual dominance and use of violence and oppression to attain food, females, and territory; in-group altruism vs. out-group hostility (us vs. them); and displays of dominance and submission to establish roles within the social hierarchy. The parallels between these features of primate society and human religious rituals and concepts make it clear that religion, especially its oppressive and violent tendencies, is rooted in the deep evolutionary past. This incisive analysis goes a long way toward explaining the historic and ongoing violence committed in the name of religion.

How did we become the linguistic, cultured, and hugely successful apes that we are? Our closest relatives--the other mentally complex and socially skilled primates--offer tantalizing clues. In Tree of Origin nine of the world's top primate experts read these clues and compose the most extensive picture to date of what the behavior of monkeys and apes can tell us about our own evolution as a species. It has been nearly fifteen years since a single volume addressed the issue of human evolution from a primate perspective, and in that time we have witnessed explosive growth in research on the subject. Tree of Origin gives us the latest news about bonobos, the make love not war apes who behave so dramatically unlike chimpanzees. We learn about the tool traditions and social customs that set each ape community apart. We see how DNA analysis is revolutionizing our understanding of paternity, intergroup migration, and reproductive success. And we confront intriguing discoveries about primate hunting behavior, politics, cognition, diet, and the evolution of language and intelligence that challenge claims of human uniqueness in new and subtle ways. Tree of Origin provides the clearest glimpse yet of the apelike ancestor who left the forest and began the long journey toward modern humanity.

Animal and human societies are multifaceted. In order to understand how they have evolved, it is necessary to investigate each of the constituent facets including individual abilities and personalities, life-history traits, mating systems, demographic dynamics, gene flows, social relationships, ecology and phylogeny. By exploring the nature and evolution of macaque social organization, this book develops our knowledge of the rise of societies and their transformation during the course of evolution. Macaques are the most comprehensively studied of all monkey groups, and the 20 known species feature a broad diversity in their social relationships, making them a particularly good group for exploring the evolution of societies. This book will be of primary interest to those studying animal behaviour and primatology, but will also be useful to those involved in the study of human societies.

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.
