This is a new edition of possibly the most exciting and innovative book on evolution in years. An international bestseller, Dawkins's superb reworking of the theory of natural selection has the rare distinction of having provoked as much interest outside the scientific community as within it. Fascinating, convincing, and beautiful in the simplicity with which complex ideas are expressed, The Selfish Gene is a classic. The revised, expanded edition contains two important new chapters. "Nice Guys Finish First" shows how cooperation can evolve even in a basically selfish world, and "The Long Reach of the Gene" advances the startling view that genes may reach outside the bodies in which they sit to manipulate other individuals--and even the world at large. The book concludes with completely new endnotes in which Dawkins replies to previous critics, or elaborates on points in the original text. Written in characteristically lively and accessible style, this new edition confirms Dawkins's reputation as one of the most brilliant biologists of his generation.
