Now in paperback, Did Darwin Get It Right discusses some of the hottest issues in biology today. Its author, the eminently quotable John Maynard Smith, discusses such fascinating conundrums as how life began, whether the brain works like a computer, why most animals and plants reproduce sexually, and how social behavior evolved out of the context of natural selection--a process which would seem to favor selfishness. A humorous and insightful writer, John Maynard Smith has the special ability to convey the excitement of science, its complexity and fascination, without baffling or boring his readers. In these 28 brief and accessible essays, Maynard ranges widely over such issues as science and the media, the birth of sociobiology, the evolution of animal intelligence and the limitations of evolutionary theory. For his work on the evolution of sex, Smith won the Darwin medal from the Royal Society, and he has pioneered the application of game theory to animal behavior.

This book is aimed at anyone with a serious interest in ecology. Ecological models of two kinds are dealt with: mathematical models of a strategic kind aimed at an understanding of the general properties of ecosystems and laboratory models designed with the same aim in view. The mathematical and experimental models illuminate one another. A strength of the account is that although there is a good deal of mathematics, Professor Maynard Smith has concentrated on making clear the assumptions behind the mathematics and the conclusions to be drawn. Proofs and derivations have been omitted as far as possible. The book is therefore comprehensible to anyone with a minimal familiarity with mathematical notation. This book was written in the twin convictions that ecology will not come of age until it has a sound theoretical basis and there is a long way to go before that state of affairs is reached.

The question of why organisms reproduce sexually is still a matter of controversy. In this account, Professor Maynard Smith considers the selective forces responsible for the origin and evolution of sexual reproduction and genetic recombination, using quantitative population genetics arguments to support his ideas. The relative importance of individual and group selection processes are also considered. the aim is to give a clear statement of the theoretical issues, and present enough of the evidence to show what kinds of facts are relevant. It is hoped that where crucial evidence is missing, experimentalists and field workers may be encouraged to collect the relevant data. The author does not claim to solve all the problems he raises, but this clear and well-argued account should provide stimulating reading for advanced undergraduate students and research workers in evolutionary theory.

By applying game theory to the problems of population biology, the author has succeeded in inventing new and interesting ways of looking at populations and has developed a theory leading to testable predictions.

The "ant" and the "peacock" stand for two puzzles in Darwinism--altruism and sexual selection. How can natural selection favor those, such as the worker ant, that renounce tooth and claw in favor of the public-spirited ways of the commune? And how can "peacocks"--flamboyant, ornamental and apparently useless--be tolerated by the grimly economical Darwinian reaper? Helena Cronin has a deep understanding of today's answers to these riddles and their roots in the nineteenth century; the analysis is new and exciting and the explanations lucid and compelling.

All living plants and animals, including man, are the modified descendants of one or a few simple living things. A hundred years ago Darwin and Wallace in their theory of natural selection, or the survival of the fittest, explained how evolution could have happened, in terms of processes known to take place today. In this book John Maynard Smith describes how their theory has been confirmed, but at the same time transformed, by recent research, and in particular by the discovery of the laws of inheritance.

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.

This second edition of Maynard Smith's now classic text on evolution and population genetics (first published 1989) has been updated throughout. It incorporates new research on game theory; the discussion of sex and host-parasite interactions have been extensively revised; and the author has added a new chapter on molecular genetics and the Teconstruction of evolutionary history. It remains an essential textbook for advanced undergraduates wishing to understand population and quantitative genetics within the context of evolutionary biology.

In this fascinating book, John Maynard Smith and Eors Szathmary present an original picture of evolution. They propose that during evolution there have been a number of major transitions in the way in which information is passed between generations. These transitions include the appearance of the first replicating molecules, the emergence of co-operative animal societies, and the unique language ability of humans. Containing many new ideas, this book is contemporary biology on the grandest scale, from the birth of life to the origin of language.

During evolution there have been several major changes in the way genetic information is organized and transmitted from one generation to the next. These transitions include the origin of life itself, the first eukaryotic cells, reproduction by sexual means, the appearance of multicellular plants and animals, the emergence of cooperation and of animal societies. This is the first book to discuss all these major transitions and their implications for our understanding of evolution. Clearly written and illustrated with many original diagrams, this book will be welcomed by students and researchers in the fields of evolutionary biology, ecology, and genetics.
