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 inThe 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.
Does Farmer Field really know his prize cow, Daisy, is in the field? When is an unexpected exam not wholly unexpected? Are all bachelors (really) unmarried? Martin Cohen’s bestselling 101 Philosophy Problems is a witty and engaging introduction to philosophy, covering classical as well as contemporary problems from the fields of medical ethics, modern physics and artificial intelligence. For the third edition, many of the problems have been revised and there are several brand new ones, including Lewis Carroll’s problem of people who don’t eat lentils and Poincare’s problem of the gaseous people whose measurements keep changing. With an updated glossary of helpful terms and possible solutions to the problems at the end of the book, 101 Philosophy Problems is essential reading for anyone coming to philosophy for the first time.
