Over the history of life 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, and the unique language ability of humans. This ambitious book provides the first unified discussion of the full range of these transitions. The authors highlight the similarities between different transitions--between the...

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...

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.

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.

This is a lucid introduction to some of the mathematical ideas which are useful to biologists.

In this account, Professor Maynard Smith considers the question of why organisms reproduce sexually and considers the selective forces responsible.
