Beschreibung

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.

Portrait

John Maynard Smith (1920-2004) was an eminent evolutionary biologist and author of many books on evolution, both for scientists and the general public. He was professor emeritus at the University of Sussex, UK, Fellow of the Royal Society, winner of the Darwin Medal, and laureate of the Crafoord Prize of the Swedish Academy of Sciences. David Harper is Senior Lecturer in Evolution, School of Biological Sciences, University of Sussex, UK.

Pressestimmen

This book is essential reading for anyone studying animal signals ... the book is well laid out, and its emphasis on clear definition and logic is without parallel in books on animal communication ... We think this book marks a significant contribution by Maynard Smith and Harper, a keystone in the communication literature, and a fitting legacy for John as it will speak discussions long after his death.
