Comparative studies have become both more frequent and more important as a means for understanding the biology, behavior, and evolution of mammals. Primates have complex social relationships and diverse ecologies, and represent a large species radiation. This book draws together a wide range of experts from diverse fields, such as reproductive biology and foraging energetics, to place recent field research into a synthetic perspective. The chapters tackle controversial issues in primate biology and behavior, including the role of brain expansion and infanticide in the evolution of primate behavioral strategies. The volume also presents an overview of comparative methodologies as applied to recent primate research.

Infanticide by males is relatively common in primates, carnivores, and rodents, although it tends to be rare even in species in which it occurs. Is this behavior pathological or accidental, or does it reflect a conditional reproductive strategy for males in certain circumstances? In this book, case studies and reviews confirm the adaptive nature of infanticide by males in primates, and help to predict which species should be vulnerable to this phenomenon. Much of the book is devoted to exploring the evolutionary consequences of the threat of infanticide by males for social and reproductive behavior and physiology. Written for graduate students and researchers in animal behavior, behavioral ecology, biological anthropology, and social psychology, this book shows that social systems are shaped by ecological pressures, as well as social pressures such as infanticide risk.

As a young student, John Crocker embarked on the adventure of a lifetime, spending eight months in the Gombe forest working with Jane Goodall. He followed families of wild chimpanzees from sunrise to sunset and learned the fundamental behavioral traits of these chimps as they raised their offspring. One chimpanzee captivated him. Her name was Fifi, and she displayed extraordinary patience and reassurance toward her infant, Freud. Upon returning home and becoming a doctor, Crocker found himself incorporating the lessons he learned from Fifi into his work as a father and physician. When he witnessed his young patients rocketing around his exam room, he would picture Fifi's patience and tacit approval of Freud's uninhibited and joyful exploration. Crocker shares how his time spent with our closest animal cousins has helped him better understand his patients with ADD, anxiety, and depression, and how primate traits hardwired into our own natural behavior help chimpanzees protect their community, raise their young, and survive. Finally, chronicling his return to Gombe thirty-six years later with his own son, he reflects on how his experience with the chimps has come full circle. An illuminating book that will raise thought-provoking questions about the evolution of human behavior and the importance of patience and strong family bonds, Following Fifi provides a greater understanding of what it means to be human.

Research on the mental abilities of chimpanzees and bonobos has been widely celebrated and used in reconstructions of human evolution. In contrast, scant attention has been paid to the abilities of gorillas and orangutans. This volume aims to complete the picture of hominoid cognition by bringing together the work on gorillas and orangutans and setting it in comparative perspective. This book's introductory chapters set the evolutionary context for comparing cognition in gorillas and orangutans to that of chimpanzees, bonobos, and humans. The remaining chapters focus primarily on the kinds and levels of intelligence displayed by orangutans and gorillas compared to other great apes, including performances in the classic domains of tool use and tool making, imitation, self awareness, social communication, and symbol use.

In this book, field and laboratory researchers show that the Great Apes are capable of thinking at symbolic levels, traditionally considered uniquely human. They show these high-level abilities in both social and ecological domains, including tool use, imitation, pretense, self-awareness, deception, consolation, teaching and proto-culture itself. Here, contributors emphasize the mechanisms involved in building these abilities--especially the lengthy developmental and "enculturation" processes--suggesting changes to current views on how primate and human intelligence have evolved. Researchers and professionals in the fields of primatology, animal behavior, anthropology, linguistics, and cognitive psychology will find much useful information in this book.

How can the intelligence of monkeys and apes, and the huge brain expansion which marked human evolution be explained? In 1988, Machiavellian Intelligence was the first book to assemble the early evidence suggesting a new answer: that the evolution of intellect was primarily driven by selection for manipulative, social expertise within groups where the most challenging problem faced by individuals was dealing with their companions. Since then a wealth of new information and ideas has accumulated. This new book will bring readers up to date with the most important developments, extending the scope of the original ideas and evaluating them empirically from different perspectives. It is essential reading for reseachers and students in many different branches of evolution and behavioural sciences, primatology, and philosophy.

What special qualities of mind set the great apes apart from other nonhuman primates, and indeed from ourselves? In this book, field and laboratory researchers show that the great apes have high level abilities in both social and ecological domains, including tool use, pretense, self-awareness, deception, consolation, teaching and culture itself. Great apes are also shown to be capable of thinking at symbolic levels, traditionally considered to be uniquely human. Here, the mechanisms involved in building these abilities - especially the lengthy developmental and 'enculturation' processes - are emphasized, showing how new discoveries are changing views on how primates and human intelligence evolved. This book is for anyone interested in current research and theoretical views of great ape cognition.

The inspiration for the film The Dark Divide starring David Cross and Debra Messing, one of America's most esteemed natural history writers takes to the hills in search of Bigfoot-and finds the wildness within ourselves. Awarded a Guggenheim Fellowship to investigate the legends of Sasquatch, Yale-trained ecologist Dr. Robert Pyle treks into the unprotected wilderness of the Dark Divide near Mount St. Helens, where he discovers both a giant fossil footprint and recent tracks. On the trail of what he thought was legend, he searches out Indians who tell him of an outcast tribe, the Seeahtiks, who had not fully evolved into humans. A handful of open-minded biologists and anthropologists counter the tabloids Pyle studies, while rogue Forest Service employees and loggers swear of a vast conspiracy to deep-six true stories of unknown, upright hominoid apes among us. He attends Sasquatch Daze, where he meets scientists, hunters, and others who have devoted their lives to the search, only to realize that "these guys don't want to find Bigfoot they want to be Bigfoot!" Since its original publication, the author's fresh experiences and finds have been added to his original work through an updated chapter. With an evaluation of recent DNA evidence from Bigfoot hair and scat, the study of speech phonemes in the "Sierra Sounds" purported Bigfoot recordings, an examination of the impact of the wildly popular Animal Planet series Bigfoot Hunters, the reemergence of the famous Bob Gimlin into the Bigfoot community, and more, Walking With Bigfoot keeps every Bigfoot enthusiast's mind wide open to one of the biggest questions in the land and brings Pyle's work on the "legend" of Bigfoot into the new century.

Colobine monkeys have a unique digestive system, analogous to that of ruminants, which allows them to exploit foliage as a food source. This gives them a niche in Old World forests where they are often the only abundant medium-sized arboreal folivorous mammal. From a possible Miocene origin, Colobine monkeys have radiated into a wide variety of forms inhabiting a range of tropical woodlands in Africa and Asia. Most of the extant species have been subject to long term field studies, but until this book, no synthesis of work on this group has been available. The central theme is that of adaptive radiation, showing how the special features of Colobine anatomy interacted with a range of ecosystems to produce the distinctive species of today. The book also discusses parallels with other mammalian groups.

This collection of articles is completely and explicitly devoted to the new field of comparative developmental evolutionary psychology--that is, to studies of primate abilities based on frameworks drawn from developmental psychology and evolutionary biology. These frameworks include Piagetian and neo-Piagetian models as well as psycholinguistic ones. The articles in this collection--originating in Japan, Spain, Italy, France, Canada, and the United States--represent a variety of backgrounds in human and nonhuman primate research. The authors focus on such areas as the nature of culture, intelligence, language, and imitation; the differences among species in mental abilities and developmental patterns; and the evolution of life histories and of mental abilities and their neurological bases.

The chimpanzee of all other living species is our closest relation, with whom we last shared a common ancestor about five million years ago. These African apes make and use a rich and varied kit of tools, and of the primates they are the only consistent and habitual tool-users and tool-makers. Chimpanzees meet the criteria of a culture as originally defined for human beings by socio-cultural anthropologists. They show sex differences in using tools to obtain and to process a variety of plant and animal foods. The technological gap between chimpanzees and human societies that live by foraging (hunter-gatherers) is surprisingly narrow at least for food-getting. Different communities of wild chimpanzees have different tool-kits and not all of this regional and local variation can be explained by the demands of the physical and biotic environments in which they live. Some differences are likely to be customs based on socially derived and symbolically encoded traditions. This book describes and analyzes the tool-use of humankind's nearest living relation. It focuses on field studies of these apes across Africa, comparing their customs to see if they can justifiably be termed cultural. It makes direct comparisons with the material culture of human foraging peoples. The book evaluates the chimpanzee as an evolutionary model, showing that chimpanzee behavior helps us to infer the origins of technology in human prehistory.

The New World primates have radiated widely in tropical America, evolving a variety of adaptations to cope with different ways of life. This comparative survey examines many species. Some are highly specialized in unique ways; others have paralleled the lemurs of Madagascar or the monkeys and apes of Africa and Asia. The author's emphasis is on natural history, behavior, and ecology. Topics include geographical distributions, habitat preferences, territorial arrangements, activity rhythms, feeding techniques, defense mechanisms, and competition and cooperation among individuals of the same species. Much of the material is new, based on recent research in the field. Social reactions and organizations, and communication systems, are discussed in order to consider their implications for the evolution of primates in general and the development of languages and intelligence. Originally published in 1976. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

This book presents an alternative to conventional ideas about the evolution of the human intellect. Instead of placing top priority on the role of tools, the pressure for their skillful use, and the related importance of interpersonal communication as a means for enhanced cooperation, this volume explores quite a different idea-- that the driving force in the evolution of human intellect was social expertise--a force which enabled the manipulation of others within the social group, who themselves are seen as posing the most challenging problems faced by primitive humans. The need to outwit one's clever colleagues then produces an evolutionary spiraling of "Machiavellian intelligence." The book forms a complete and self-contained text on this fast-growing topic. It includes the origins of the basic premise and a wealth of exciting developments, described by an international team of authors from the fields of anthropology, psychology, and zoology. An evaluation of more traditional approaches is also undertaken, with a view to discovering to what extent Machiavellian intelligence represents a complementary concept or one that is truly an alternative. Readers and students will find this fascinating volume carries them to the frontiers of scientific work on the origin of human intellect.

Our closest living relatives, the chimpanzees, are familiar enough--bright and ornery and promiscuous. But they also kill and eat their kin, in this case the red colobus monkey, which may say something about primate--even hominid--evolution. This book, the first long-term field study of a predator-prey relationship involving two wild primates, documents a six-year investigation into how the risk of predation molds primate society. Taking us to Gombe National Park in Tanzania, a place made famous by Jane Goodall's studies, the book offers a close look at how predation by wild chimpanzees--observable in the park as nowhere else--has influenced the behavior, ecology, and demography of a population of red colobus monkeys.

As he explores the effects of chimpanzees' hunting, Craig Stanford also asks why these creatures prey on the red colobus. Because chimpanzees are often used as models of how early humans may have lived, Stanford's findings offer insight into the possible role of early hominids as predators, a little understood aspect of human evolution.

The first book-length study in a newly emerging genre of primate field study, "Chimpanzee and Red Colobus "expands our understanding of not just these two primate societies, but also the evolutionary ecology of predators and prey in general.

In 1838 Charles Darwin jotted in a notebook, "He who understands baboon would do more towards metaphysics than Locke." "Baboon Metaphysics "is Dorothy L. Cheney and Robert M. Seyfarth's fascinating response to Darwin's challenge.
Cheney and Seyfarth set up camp in Botswana's Okavango Delta, where they could intimately observe baboons and their social world. Baboons live in groups of up to 150, including a handful of males and eight or nine matrilineal families of females. Such numbers force baboons to form a complicated mix of short-term bonds for mating and longer-term friendships based on careful calculations of status and individual need.
But "Baboon Metaphysics" is concerned with much more than just baboons' social organization--Cheney and Seyfarth aim to fully comprehend the intelligence that underlies it. Using innovative field experiments, the authors learn that for baboons, just as for humans, family and friends hold the key to mitigating the ill effects of grief, stress, and anxiety.
Written with a scientist's precision and a nature-lover's eye, "Baboon Metaphysics" gives us an unprecedented and compelling glimpse into the mind of another species.
"The vivid narrative is like a bush detective story."--Steven Poole, "Guardian"
""Baboon Metaphysics "is a distillation of a big chunk of academic lives. . . . It is exactly what such a book should be--full of imaginative experiments, meticulous scholarship, limpid literary style, and above all, truly important questions."--Alison Jolly, "Science"
"Cheney and Seyfarth found that for a baboon to get on in life involves a complicated blend of short-term relationships, friendships, and careful status calculations. . . . Needless to say, the ensuing political machinations and convenient romantic dalliances in the quest to become "numero uno" rival the bard himself."--"Science News" "Cheney and Seyfarth's enthusiasm is obvious, and their knowledge is vast and expressed with great clarity. All this makes "Baboon Metaphysics" a captivating read. It will get you thinking--and maybe spur you to travel to Africa to see it all for yourself."--Asif A. Ghazanfar, "Nature"
"Through ingenious playback experiments . . . Cheney and Seyfarth have worked out many aspects of what baboons used their minds for, along with their limitations. Reading a baboon's mind affords an excellent grasp of the dynamics of baboon society. But more than that, it bears on the evolution of the human mind and the nature of human existence."--Nicholas Wade, "New York"" Times"

Robin Dunbar uses economic models to explore the social behavior of the gelada baboon (Theropithecus gelada), a unique species, whose social system is one of the most complex among the primates. His work illustrates the value of an approach that views social behavior as being ultimately concerned with reproduction and with the maximizing of an individual's contribution to its species' gene pool.

From foraging patterns in a single tree to social interactions across a home range, how primates use space is a key question in the field of primate behavioral ecology. Drawing on the latest advances in spatial analysis tools, this book offers practical guidance on applying geographic information systems (GIS) to central questions in primatology. An initial methodological section discusses niche modelling, home range analysis and agent-based modelling, with a focus on remote data collection. Research-based chapters demonstrate how ecologists apply this technology to a suite of topics including: calculating the intensity of use of both range and travel routes, assessing the impacts of logging, mining and hunting, and informing conservation strategies.

Archaeoprimatology intertwines archaeology and primatology to understand the ancient liminal relationships between humans and nonhuman primates. During the last decade, novel studies have boosted this discipline. This edited volume is the first compendium of archaeoprimatological studies ever produced. Written by a culturally diverse group of scholars, with multiple theoretical views and methodological perspectives, it includes new zooarchaeological examinations and material culture evaluations, as well as innovative uses of oral and written sources. Themes discussed comprise the survey of past primates as pets, symbolic mediators, prey, iconographic references, or living commodities. The book covers different regions of the world, from the Americas to Asia, along with studies from Africa and Europe. Temporally, the chapters explore the human-nonhuman primate interface from deep in time to more recent historical times, examining both extinct and extant primate taxa. This anthology of archaeoprimatological studies will be of interest to archaeologists, primatologists, anthropologists, art historians, paleontologists, conservationists, zoologists, historical ecologists, philologists, and ethnobiologists.

This is a re-examination of the story around the capture and disappearance of a mysterious creature in BC in 1884.

Despite many encouraging developments in the field of animal-free technologies, well-defined animal models are still needed to study fundamental properties of human diseases and to develop new prophylactic and therapeutic treatments against human diseases. Non-human primates (NHP) make up only a small, but important, part of the total number of animals used in biomedical and preclinical research. Due to their close phylogenetic relationship and the shared susceptibility to many human diseases, NHP can provide important research models to study these diseases and, as such, play a critical role in the advancement of various areas in the medical field. Studies in NHP have contributed to our understanding of various diseases and fundamental biological phenomena and they continue to be important in the development of new therapies, treatments, drugs and vaccines. Moreover, NHP models also contribute to our general knowledge of the processes that underlie non-disease and disease conditions. Important areas where NHP can provide important information include (emerging) infectious diseases, organ transplantation, neurological and aging-related disorders. Although not covered in this book due to time constraints, the need for, and benefits of, NHP models has been demonstrated most recently in the SARS-CoV-2 pandemic. The present book is the second of two volumes and covers important disease areas where NHP are used as model species. This volume includes different chapters on NHP models in infectious diseases, aging, neurodegenerative disorders, organ transplantation and cancer.
