This volume analyzes the behavioral interactions between infant and adult male baboons. The result is the first quantitative description of infant-adult male relations for any higher primate, including humans. The idea that emerges is that infant-adult male relations are far more complex than the mere paternal caretaking or exploitation that has previously been assumed, and these relations are specific, long-term, reciprocal, and beneficial to both infants and the adult males. The book also deals with many current topics of interest, including parental investment, kidnapping, altruism, food sharing, agonistic buffering, adoption, and infanticide.

The book aims to integrate our understanding of mammalian societies into a novel synthesis that is relevant to behavioural ecologists, ecologists, and anthropologists. It adopts a coherent structure that deals initially with the characteristics and strategies of females, before covering those of males, cooperative societies and hominid societies. It reviews our current understanding both of the structure of societies and of the strategies of individuals; it combines coverage of relevant areas of theory with coverage of interspecific comparisons, intraspecific comparisons and experiments; it explores both evolutionary causes of different traits and their ecological consequences; and it integrates research on different groups of mammals with research on primates and humans and attempts to put research on human societies into a broader perspective.

Those who have been privileged to watch baboons long enough to know them as individuals and who have learned to interpret some of their more subtle interactions will attest that the rapid flow of baboon behavior can at times be overwhelming. In fact, some of the most sophisticated and influential observation methods for sampling vertebrate social behavior grew out of baboon studies, invented by scientists who were trying to cope with the intricacies of baboon behavior. Barbara Smuts' eloquent study of baboons reveals a new depth to their behavior and extends the theories needed to account for it.While adhering to the most scrupulous methodological strictures, the author maintains an open research strategy--respecting her subjects by approaching them with the open mind of an ethnographer and immersing herself in the complexities of baboon social life before formulating her research design, allowing her to detect and document a new level of subtlety in their behavior. At the Gilgil site, described in this book, she could stroll and sit within a few feet of her subjects. By maintaining such proximity she was able to watch and listen to intimate exchanges within the troop; she was able, in other words, to shift the baboons well along the continuum from ""subject"" to ""informant."" By doing so she has illuminated new networks of special relationships in baboons. This empirical contribution accompanies theoretical insights that not only help to explain many of the inconsistencies of previous studies but also provide the foundation for a whole new dimension in the study of primate behavior: analysis oft he dynamics of long-term, intimate relationships and their evolutionary significance.At every stage of research human observers have underestimated the baboon. These intelligent, curious, emotional, and long-lived creatures are capable of employing stratagems and forming relationships that are not easily detected by traditional research methods. In the process

A major contribution to great-ape research, covering every aspect of the Mahale Mountain Chimpanzee Project to offer new, unique insights.

This international symposium contains 18 papers contributed by primatologists from both Japan and the United States. In them are many definitions of problems as well as techniques and methods for investigating and understanding nonhuman primate behavior.

These original contributions on the evolution of primates and the techniques for studying the subject cover an enormous range of material and incorporate the work of specialists from many different fields, showing the necessity of a multidisciplinary approach to problems of primate morphology and phylogeny. Collectively, they demonstrate the concerns and methods of leading contemporary workers in this and related fields. Each contributor shows his way of attacking fundamental problems of evolutionary primatology.
