Gull chicks beg for food from their parents. Peacocks spread their tails to attract potential mates. Meerkats alert family members of the approach of predators. But are these--and other animals--sometimes dishonest? That's what William Searcy and Stephen Nowicki ask in The Evolution of Animal Communication. They take on the fascinating yet perplexing question of the dependability of animal signaling systems. The book probes such phenomena as the begging of nesting birds, alarm calls in squirrels and primates, carotenoid coloration in fish and birds, the calls of frogs and toads, and weapon displays in crustaceans. Do these signals convey accurate information about the signaler, its future behavior, or its environment? Or do they mislead receivers in a way that benefits the signaler? For example, is the begging chick really hungry as its cries indicate or is it lobbying to get more food than its brothers and sisters? Searcy and Nowicki take on these and other questions by developing clear definitions of key issues, by reviewing the most relevant empirical data and game theory models available, and by asking how well theory matches data. They find that animal communication is largely reliable--but that this basic reliability also allows the clever deceiver to flourish. Well researched and clearly written, their book provides new insight into animal communication, behavior, and evolution.

This book seeks to combine the study of human social cognition - the way we think, decide, plan and analyze social situations - with an evolutionary framework that considers these activities in light of evolutionary adaptations for solving problems of survival faced by our ancestors over thousands of generations. The chapters report recent research and theories illustrating how evolutionary principles can shed new light on the subtle and often subconscious ways that cognitive mechanisms guide peoples’ thoughts, memories, judgments, attitudes and behaviors in social life. The contributors to this volume, who are leading researchers in their fields, seek answers to such intriguing questions as: how can evolutionary principles help to explain human beliefs, attitudes, judgments, prejudice, and group preferences? Are there benefits to behaving unpredictably? Why are prototypical faces more attractive than atypical ones? How do men and women think about, and select potential mates? What are the adaptive functions of negative affect? What are the evolutionary influences on the way people think about and respond to social exclusion and ostracism? Evolution and the Social Mind offers a highly integrated and representative coverage of this emerging field, and is suitable as a textbook in advanced courses dealing with social cognition and evolutionary psychology.

Rock art is one of the most visible and geographically widespread of cultural expressions, and it spans much of the period of our species' existence. Rock art also provides rare and often unique insights into the minds and visually creative capacities of our ancestors and how selected rock outcrops with distinctive images were used to construct symbolic landscapes and shape worldviews. Equally important, rock art is often central to the expression of and engagement with spiritual entities and forces, and in all these dimensions it signals the diversity of cultural practices, across place and through time. Over the past 150 years, archaeologists have studied ancient arts on rock surfaces, both out in the open and within caves and rock shelters, and social anthropologists have revealed how people today use art in their daily lives. The Oxford Handbook of the Archaeology and Anthropology of Rock Art showcases examples of such research from around the world and across a broad range of cultural contexts, giving a sense of the art's regional variability, its antiquity, and how it is meaningful to people in the recent past and today - including how we have ourselves tended to make sense of the art of others, replete with our own preconceptions. It reviews past, present, and emerging theoretical approaches to rock art investigation and presents new, cutting-edge methods of rock art analysis for the student and professional researcher alike.
