内容説明
Why are animal signals reliable? This is the central problem for evolutionary biologists interested in signals. Of course, not all signals are reliable; but most are, otherwise receivers of signals would ignore them. A number of theoretical answers have been proposed and empirical studies made, but there still remains a considerable amount of confusion. The authors, one a theoretician the other a fieldworker, introduce a sense of order to this chaos. A significant cause of confusion has been the tendency for different researchers to use either the same term with different meanings, or different terms with the same meaning. The authors attempt to clarify these differences. A second cause of confusion has arisen because many biologists continue to assume that there is only one correct explanation for signal reliability. The authors argue that the reliability of signals is maintained in several ways, relevant in different circumstances, and that biologists must learn to distinguish between them.
In this book they explain the different theories, give examples of signalling systems to which one or another theory applies, and point to the many areas where further work, both theoretical and empirical, is required. John Maynard Smith is one of the most influential scientists of his generation and his theories have transformed our understanding of animal behaviour, whilst David Harper is a reknowned field ecologist. Animal signals are one of the hottest and most controversial subjects in animal behaviour, and are also of major importance to an understanding of human behaviour and the evolution of language.

内容説明
Why are most animal signals reliable? This is the central problem for evolutionary biologists interested in signals. A number of theoretical answers have been proposed and empirical studies made, but a considerable amount of confusion still remains. The authors, one a theoretician the other a fieldworker, introduce a sense of order to this chaos.
They disentangle the complex and often confusing terminology that characterises the subject, and then challenge the widely held assumption that there is only one correct explanation for signal reliability. The authors argue that the reliability of signals is maintained in several ways, relevant in different circumstances, and that biologists must learn to distinguish between them. In this book they explain the different theories, give examples of signalling systems to which one or another
theory applies, and point to the many areas where further work, both theoretical and empirical, is required.
