Descripción editorial
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.
PUBLISHERS WEEKLY
How did life on Earth go from individual molecules in hot carbon soup to viral spirals, to cells, to sex cells, to us? Smith and Szathmary's The Major Transitions in Evolution (1995), addressed to other evolutionary biologists, responded to this question by reviewing Darwinism through the lens of information theory. The authors' new work brings nonexpert readers an "account of the evolution of complexity," of changes in the ways "genetic information... is stored, transmitted and translated." Smith and Szathmary (professors, respectively, at the University of Sussex, England, and the Collegium Budapest, Hungary) apply their model to periods in the history of life, from the era of the first self-replicating molecules to the advent of chromosomes and thence to cells and cell walls, sexual differentiation and mating, symbiosis between species, animal societies and symbolic speech. Directing their interest in information transfer to biological processes and epochs, they cover topics ranging from the definition of life (why do we not call fire "alive"?) to the basis of tribal warfare. 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 co-operate rather than compete." A chapter on sex offers several theories of how it arose; a later chapter examines the origins of our built-in ways of understanding and generating grammatical sentences in our native languages. Compact, dense, formidable yet accessible, this book exposes readers to the cutting edge in theoretical evolutionary biology.
