When John Maynard Smith and Eörs Szathmáry published The Major Transitions in Evolution , it was seen as a major work in biology. Nature hailed it as a book of "grand and daunting sweep...A splendid and rewarding tour de force ." And New Scientist wrote that it captured "the essence of modern biology," calling it "an extremely significant book which, as a bonus, is very readable." Now, in The Origins of Life , Maynard Smith and Szathmáry have completely rewritten Transitions to bring their ideas to a wider audience of general readers. Here is a brilliant, original picture of how life evolved on earth, focusing primarily on six major transitionsdramatic breakthroughs in the way that information was passed between generations. The authors offer illuminating explorations of the origin of life itself, the arrival of the first cells with nuclei, the first reproduction by sexual means, the appearance of multicellular plants and animals, the emergence of cooperative animal societies, and the birth of language. The Origins of Life represents the thinking of two leading scientists on questions that engage us allhow life began and how it gradually evolved from tiny invisible cells into whales and trees and human beings. "Moving speedily from epoch to epoch, fueled by a few important concepts (such as the division of labor) and explaining all the genetics they use, Smith and Szathmary show `just how difficult it has been to evolve complex organisms whose genes cooperate rather than compete'.... Compact, dense, formidable yet accessible, this book exposes readers to the cutting edge in theoretical evolutionary biology."-- Publishers Weekly A landmark work by two leading biologists, illuminating the path of evolution from the first tiny cells to human beings--now rewritten for general readers John Maynard Smith is an internationally renowned biologiest, widely respected for the originality of his ideas and quality of his thinking. He is a Professor in the School of Biological Sciences, University of Sussex. Eors Szathmary is a Professor at the Collegium Budapest, in Hungary.
