This volume reviews the meaning of taxonomic statements and considers our present knowledge regarding the number and characteristics of species among living and extinct primates, including man and his ancestors. They also examine the relationship of behaviour changes and selection pressures in evolutionary sequences. First published in 1964.

A comprehensive account of the origins, evolution, and behavior of South and Central American primates New World Monkeys brings to life the beauty of evolution and biodiversity in action among South and Central American primates, who are now at risk. These tree-dwelling rainforest inhabitants display an unparalleled variety in size, shape, hands, feet, tails, brains, locomotion, feeding, social systems, forms of communication, and mating strategies. Primatologist Alfred Rosenberger, one of the foremost experts on these mammals, explains their fascinating adaptations and how they came about. New World Monkeys provides a dramatic picture of the sixteen living genera of New World monkeys and a fossil record that shows that their ancestors have lived in the same ecological niches for up to 20 million years-only to now find themselves imperiled by the extinction crisis. Rosenberger also challenges the argument that these primates originally came to South America from Africa by floating across the Atlantic on a raft of vegetation some 45 million years ago. He explains that they are more likely to have crossed via a land bridge that once connected Western Europe and Canada at a time when many tropical mammals transferred between the northern continents. Based on the most current findings, New World Monkeys offers the first synthesis of decades of fieldwork and laboratory and museum research conducted by hundreds of scientists.

The dwarf and mouse lemurs of Madagascar are two very species-rich lemur genera, yet there is a relative paucity of information on this primate family in published literature. In this first ever treatment of the Cheirogaleidae, international experts are brought together to review and integrate our current knowledge of the behaviour, physiology, ecology, genetics and biogeography of these species. A wide range of direct and indirect research methods that are currently used to study these cryptic nocturnal solitary foragers are described. By uniting often disparate research on captive and free-ranging taxa and synthesising recent methodological advances, this book provides new insights that will encourage further studies of this fascinating primate family. This synthesis will provide an incentive for more integrative studies of the Cheirogaleidae in captivity and in the wild, enabling the impacts of deforestation and other factors to be identified and directions for future conservation efforts to be established.

The Arashiyama group of Japanese macaques holds a distinguished place in primatology as one of the longest continuously studied non-human primate populations in the world. The resulting long-term data provide a unique resource for researchers, allowing them to move beyond cross-sectional studies to tackle larger issues involving individual, matrilineal and group histories. This book presents an overview of the scope and magnitude of research topics and management efforts that have been conducted on this population for several decades, covering not only the original troop living around Kyoto, Japan, but also the two subgroups that were translocated to Texas, USA and Montreal, Canada. The chapters encompass topics including life history, sexual, social and cultural behaviour and ecology, giving an insight into the range of current primatological research. The contributors underscore the historic value of the Arashiyama macaques and showcase new and significant research findings that highlight their continuing importance to primatology.

This book provides a novel focus on adaptive explanations for cranial and postcranial features and functional complexes, socioecological systems, life history patterns, etc. in early primates. It further offers a detailed rendering of the phylogenetic affinities of such basal taxa to later primate clades as well as to other early/recent mammalian orders. In addition to the strictly paleontological or systemic questions regarding Primate Origins, the editors concentrate on the adaptive significance of primate characteristics. Thus, the book provides the broadest possible perspective on early primate phylogeny and the adaptive uniqueness of the Order Primates.

Primate tourism is a growing phenomenon, with increasing pressure coming from several directions: the private sector, governments, and conservation agencies. At the same time, some primate sites are working to exclude or severely restrict tourism because of problems that have developed as a result. Indeed, tourism has proven costly to primates due to factors such as disease, stress, social disruption, vulnerability to poachers, and interference with rehabilitation and reintroduction. Bringing together interdisciplinary expertise in wildlife/nature tourism and primatology, experts present and discuss their accumulated experience from individual primate sites open to tourists, formal studies of primate-focused tourism, and trends in nature and wildlife tourism. Chapters offer species- and site-specific assessments, weighing conservation benefits against costs, and suggesting strategies for the development of informed guidelines for ongoing and future primate tourism ventures. Primate Tourism has been written for primatologists, conservationists and other scientists. It is also relevant to tourists and tourism professionals.

Living in the remote forests of western central Africa, the mandrill (Mandrillus sphinx) is notoriously elusive and has evaded scientific scrutiny for decades. Yet, it is the largest and most sexually dimorphic of all the Old World monkeys, and perhaps the most colourful of all the mammals. Synthesising the results of more than twenty-five years of research, this is the first extensive treatment of the mandrill's reproductive and behavioural biology. Dixson explores in detail the role that sexual selection has played in shaping the mandrill's evolution, covering mechanisms of mate choice, intra-sexual competition, sperm competition and cryptic female choice. Bringing to life, through detailed descriptions and rich illustrations, the mandrill's communicatory biology and the functions of its brightly coloured adornments, this book sheds new light on the evolutionary biology of this fascinating primate.

Chimpanzees fascinate people for many reasons. We are struck by the apes' resemblance to humanity, as seen in their use of tools and their complex social lives, and we are moved by the threats that human activity poses to them. Our awareness of our closest living relatives testifies to the efforts of the remarkable people who study these creatures and work to protect them. What motivates someone to dedicate their lives to chimpanzees? How does that reflect on our own species? This book brings together a range of chimpanzee experts who tell powerful personal stories about their lives and careers. It features some of the world's preeminent primatologists-including Jane Goodall and Frans de Waal-as well as representatives of a new generation from varied backgrounds. In addition to field scientists, the book features anthropologists, biologists, psychologists, veterinarians, conservationists, and the director of a chimpanzee sanctuary. Some grew up in the English countryside, others in villages in Congo; some first encountered chimpanzees in a zoo, others in the forests surrounding their homes. All are united by a common purpose: to study and understand chimpanzees in order to protect them in the wild and care for them in zoos and sanctuaries. Contributors share what inspired them, what shaped their career choices, and what motivates them to strive for solutions to the many challenges that chimpanzees face today.

The first ethnographic exploration of the contentious debate over whether nonhuman primates are capable of culture In the 1950s, Japanese zoologists took note when a number of macaques invented and passed on new food-washing behaviors within their troop. The discovery opened the door to a startling question: Could animals other than humans share social knowledge-and thus possess culture? The subsequent debate has rocked the scientific world, pitting cultural anthropologists against evolutionary anthropologists, field biologists against experimental psychologists, and scholars from Asia against their colleagues in Europe and North America. In Chimpanzee Culture Wars, the first ethnographic account of the battle, anthropologist Nicolas Langlitz presents first-hand observations gleaned from months spent among primatologists on different sides of the controversy. Langlitz travels across continents, from field stations in the Ivory Coast and Guinea to laboratories in Germany and Japan. As he compares the methods and arguments of the different researchers he meets, he also considers the plight of cultural primatologists as they seek to document chimpanzee cultural diversity during the Anthropocene, an era in which human culture is remaking the planet. How should we understand the chimpanzee culture wars in light of human-caused mass extinctions? Capturing the historical, anthropological, and philosophical nuances of the debate, Chimpanzee Culture Wars takes us on an exhilarating journey into high-tech laboratories and breathtaking wilderness, all in pursuit of an answer to the question of the human-animal divide.

This book discusses the hypothesis that the primate pulvinar contains an original scaffold which is derived from cytoarchitectural markers and specific protein distributions. Thereafter, along primate evolution, different selective pressures acted in order to shape and fine-tune the connectivity of the pulvinar with specific regions of the neocortex. This divergence created, among other things, the different sets of retinotopic map representations in the pulvinar nucleus depending on functional and behavioral requirements of each species. The pulvinar, the largest nucleus of the primate thalamus, has extensive and reciprocal connections with several areas of the neocortex. These input-output loops suggest that the pulvinar may regulate the flow of information within and between cortical areas in a highly dynamic fashion. Therefore, understanding the anatomical subdivisions within the pulvinar, and its connectivity with the cortex, is paramount to understanding pulvinar physiological function. However, there is a stark contrast regarding the way that the pulvinar is subdivided depending on the technique employed. Cytoarchitectural and immunohistochemical methods reveal a very similar pattern of pulvinar subdivision across Old- and New-World monkeys. On the other hand, electrophysiological and connectivity studies expose clear discrepancies in pulvinar organization across primate evolution.

How did social communication evolve in primates? In this volume, primatologists, linguists, anthropologists, cognitive scientists and philosophers of science systematically analyze how their specific disciplines demarcate the research questions and methodologies involved in the study of the evolutionary origins of social communication in primates in general and in humans in particular. In the first part of the book, historians and philosophers of science address how the epistemological frameworks associated with primate communication and language evolution studies have changed over time and how these conceptual changes affect our current studies on the subject matter. In the second part, scholars provide cutting-edge insights into the various means through which primates communicate socially in both natural and experimental settings. They examine the behavioral building blocks by which primates communicate and they analyze what the cognitive requirements are for displaying communicative acts. Chapters highlight cross-fostering and language experiments with primates, primate mother-infant communication, the display of emotions and expressions, manual gestures and vocal signals, joint attention, intentionality and theory of mind. The primary focus of the third part is on how these various types of communicative behavior possibly evolved and how they can be understood as evolutionary precursors to human language. Leading scholars analyze how both manual and vocal gestures gave way to mimetic and imitational protolanguage and how the latter possibly transitioned into human language. In the final part, we turn to the hominin lineage, and anthropologists, archeologists and linguists investigate what the necessary neurocognitive, anatomical and behavioral features are in order for human language to evolve and how language differs from other forms of primate communication.

What can the study of young monkeys and apes tell us about the minds of young humans? In this fascinating introduction to the study of primate minds, Juan Carlos Gomez identifies evolutionary resemblances--and differences--between human children and other primates. He argues that primate minds are best understood not as fixed collections of specialized cognitive capacities, but more dynamically, as a range of abilities that can surpass their original adaptations.

In a lively overview of a distinguished body of cognitive developmental research among nonhuman primates, Gomez looks at knowledge of the physical world, causal reasoning (including the chimpanzee-like errors that human children make), and the contentious subjects of ape language, theory of mind, and imitation. Attempts to teach language to chimpanzees, as well as studies of the quality of some primate vocal communication in the wild, make a powerful case that primates have a natural capacity for relatively sophisticated communication, and considerable power to learn when humans teach them.

Gomez concludes that for all cognitive psychology's interest in perception, information-processing, and reasoning, some essential functions of mental life are based on ideas that cannot be explicitly articulated. Nonhuman and human primates alike rely on implicit knowledge. Studying nonhuman primates helps us to understand this perplexing aspect of all primate minds.

'One of history's most impressive field studies; an instant animal classic' TIME Jane Goodall's classic account of primate research provides an impressively detailed and absorbing account of the early years of her field study of, and adventures with, chimpanzees in Tanzania, Africa. It is a landmark for everyone to enjoy.

Are humans by nature hierarchical or egalitarian? "Hierarchy in the Forest" addresses this question by examining the evolutionary origins of social and political behavior. Christopher Boehm, an anthropologist whose fieldwork has focused on the political arrangements of human and nonhuman primate groups, postulates that egalitarianism is in effect a hierarchy in which the weak combine forces to dominate the strong.

The political flexibility of our species is formidable: we can be quite egalitarian, we can be quite despotic. "Hierarchy in the Forest" traces the roots of these contradictory traits in chimpanzee, bonobo, gorilla, and early human societies. Boehm looks at the loose group structures of hunter-gatherers, then at tribal segmentation, and finally at present-day governments to see how these conflicting tendencies are reflected.

"Hierarchy in the Forest" claims new territory for biological anthropology and evolutionary biology by extending the domain of these sciences into a crucial aspect of human political and social behavior. This book will be a key document in the study of the evolutionary basis of genuine altruism.

Reconstructing the paleobiology of fossil non-human primates, this book is intended as an exposition of non-human primate evolution that includes information about evolutionary theory and processes, paleobiology, paleoenvironment, how fossils are formed, how fossils illustrate evolutionary processes, the reconstruction of life from fossils, the formation of the primate fossil record, functional anatomy, and the genetic bases of anatomy. Throughout, the emphasis of the book is on the biology of fossil primates, not their taxonomic classification or systematics, or formal species descriptions. The author draws detailed pictures of the paleoenvironment of fossil primates, including contemporary animals and plants, and ancient primate communities, emphasizing our ability to reconstruct lifeways from fragmentary bones and teeth, using functional anatomy, stable isotopes from enamel and collagen, and high resolution CT-scans of the cranium. Fossil Primates will be essential reading for advanced undergraduates and graduate students in evolutionary anthropology, primatology and vertebrate paleobiology.

Humans views of other primates include myths and legends, accounts of early European naturalists, artistic interpretations, and natural histories, anatomical studies and collections. This book synthesizes all these different perspectives and reveals something about our perceived place in the natural world. The international team of contributors provides an integrative rendering of primates and fills a unique niche. It will be of interest to both undergraduate and graduate students as well as to scholars of different disciplines such as history of science, natural science, comparative anatomy, biology, anthropology, sociology, ethnoprimatology, paleontology and anthrozoology among others. Key selling features: Integrates various perspectives and perceptions of non-human primates Summarizes history of science and the ways art and culture influenced science Documents non-human primates with lavishly illustrated text Includes contributions from an international team of historians of science, natural scientists, comparative anatomists, biologists, anthropologists, sociologists, paleontologists and zoologists

Current dominant thinking and practice in the private and public sectors asserts that peoples' development needs are in conflict with, or mutually exclusive to, the need to conserve the biosphere on which we depend. Consequently, we are asked to either diminish development in the name of conservation or diminish conservation in the name of development. Efforts to identify complementary objectives, or mutually acceptable trade-offs and compromises indicate, however, that this does not always have to be the case. This first volume in the State of the Apes series draws attention to the evolving context within which great ape and gibbon habitats are increasingly interfacing with extractive industries. Intended for a broad range of policy makers, industry experts, decision makers, academics, researchers and NGOs, these publications aim to influence debate, practice and policy, seeking to reconcile ape conservation and welfare, and economic and social development, through objective and rigorous analysis.

The number of primates on the brink of extinction continues to grow, and the need to respond with effective conservation measures has never been greater. This book provides a comprehensive and state-of-the-art synthesis of research principles and applied management practices for primate conservation. It begins with a consideration of the biological, intellectual, economic, and ecological importance of primates and a summary of the threats that they face, before going on to consider these threats in more detail with chapters on habitat change, trade, hunting, infectious diseases, and climate change. Potential solutions in the form of management practice are examined in detail, including chapters on conservation genetics, protected areas, and translocation. An Introduction to Primate Conservation brings together an international team of specialists with wide-ranging expertise across primate taxa. This is an essential textbook for advanced undergraduates, graduate students, and established researchers in the fields of primate ecology and conservation biology. It will also be a valuable reference for conservation practitioners, land managers, and professional primatologists worldwide.

How do chimpanzees say, 'I want to have sex with you?' By clipping a leaf or knocking on a tree trunk? How do they eat live aggressive ants? By using a short stick with one hand or long stick with both? Ivorian and Tanzanian chimpanzees answer these questions differently, as would humans from France and China if asked how they eat rice. Christophe Boesch takes readers into the lives of chimpanzees from different African regions, highlighting the debate about culture. His ethnography reveals how simple techniques have evolved into complex ones, how teaching styles differ, how material culture widens access to new food sources and how youngsters learn culture. This journey reveals many parallels between humans and chimpanzees and points to striking differences. Written in a vivid and accessible style, Wild Cultures places the reader in social and ecological contexts that shed light on our twin cultures.

Primates communicate with each other using a wide range of signals: olfactory signals to mark territories, screams to recruit help while fighting, gestures to request food and facial expressions to initiate play. Primate Communication brings together research on all forms of interchange and discusses what we know about primate communication via vocal, gestural, facial, olfactory and integrated multimodal signals in relation to a number of central topics. It explores the morphological, neural and cognitive foundations of primate communication through discussion of cutting-edge research. By considering signals from multiple modalities and taking a unified multimodal approach, the authors offer a uniquely holistic overview of primate communication, discussing what we know, what we don't know and what we may currently misunderstand about communication across these different forms. It is essential reading for researchers interested in primate behaviour, communication and cognition, as well as students of primatology, psychology, anthropology and cognitive sciences.

Coordination in Human and Primate Groups presents one of the first collections of the different approaches and methods used to assess coordination processes in groups. Written by psychologists and primatologists, the book represents a broad range of coordination research fields such as social psychology, work and organizational psychology, medicine, primatology, and behavioural ecology. It is designed for researchers and practitioners interested in understanding the behavioural aspects of group coordination.

The neotropical primate family Pitheciidae consists of four genera Cacajao (uacaris), Callicebus (titis), Chiropotes (bearded sakis) and Pithecia (sakis), whose 40+ species display a range of sizes, social organisations, ecologies and habitats. Few are well known and the future survival of many is threatened, yet pitheciines have been little studied. This book is the first to review the biology of this fascinating and diverse group in full. It includes fossil history, reviews of the biology of each genus and, among others, specific treatments of vocalisations and foraging ecology. These studies are integrated into considerations of current status and future conservation requirements on a country-by-country basis for each species. A state-of-the-art summary of current knowledge, Evolutionary Biology and Conservation of Titis, Sakis and Uacaris is a collective effort from all the major researchers currently working on these remarkable animals.

In 2001, first reports of the human draft genome were published. Since then, genomes of many other organisms have been sequenced, including several primate species: the chimpanzee, rhesus macaque, gorilla, orangutan, gibbon, baboon, marmoset, tarsier, galago, lemur, and more recently Neanderthals. In a new era of "post-genome biology", scientists now have the vast amount of information revealed by genome research to confront one of the most challenging, fundamental questions in primatology and anthropology: What makes us human? This volume comprises a collection of articles on a variety of topics relevant to primate genomes, including evolution, human origins, genome structure, chromosome genomics, and bioinformatics. The book covers the cutting-edge research in molecular primatology and provides great insights into the functional diversity of primates. This valuable collection will benefit researchers and students, including primatologists, anthropologists, molecular biologists, evolutionary biologists, and animal behaviorists.

This seminal work chronicles George B. Schaller's two years of travel and observation of gorillas in East and Central Africa in the late 1950s, high in the Virunga volcanoes on the Zaire-Rwanda-Uganda border. There, he learned that these majestic animals, far from being the aggressive apes of film and fiction, form close-knit societies of caring mothers and protective fathers watching over playful young. Alongside his observations of gorilla society, Schaller celebrates the enforced yet splendid solitude of the naturalist, recounts the adventures he experienced along the way, and offers a warning against poaching and other human threats against these endangered creatures. This edition features a postscript detailing Schaller's more recent visits with gorillas, current to 2009.

"Whether the author is tracking gorillas, slipping past elephant herds on narrow jungle paths, avoiding poachers' deadfalls, or routing Watusi invaders, this is an exciting book. Although Schaller feels that this is 'not an adventure book, ' few readers will be able to agree."--Irven DeVore, "Science"
