By suggesting that individual organisms should be viewed as a single coherent unit, working to maximize their own reproductive success, the author explains that as these organisms are "selfish" they have the capacity to effect the body of another animal, so revolutionizing our views of adaptation. Dawkins shows that some such revolution is logically necessary, as genes can be said to have extended phenotypes outside the body in which they sit. Other topics that the book examines include the theory of evolutionary stable strategies, the relationship between Darwinian and Lamarckian theories of general adaptation and the suggestion, first made in "The Selfish Gene", Dawkin's controversial first book, and also recently reopened by molecular biologists under the catchphrase "Selfish DNA", that some of the surplus DNA in eukaryotic genomes may be parasitic. In the final chapter the author returns to the individual organism as a phenomenon that needs explaining in its own right. Dawkin has also written "The Blind Watchmaker".

Summary: People commonly view evolution as a process of competition between individuals--known as "survival of the fittest"--with the individual representing the "unit of selection." Richard Dawkins offers a controversial reinterpretation of that idea in The Extended Phenotype, now being reissued to coincide with the publication of the second edition of his highly-acclaimed The Selfish Gene. He proposes that we look at evolution as a battle between genes instead of between whole organisms. We can then view Nanges in phenotypes--the end products of genes, like eye color or leaf shape, which are usually considered to increase the fitness of an individual--as serving the evolutionary interests of genes. Dawkins makes a convincing case that considering one's body, personality, and environment as a field of combat in a kind of "arms race" between genes fighting to express themselves on a strand of DNA can clarify and extend the idea of survival of the fittest. This influential and controversial book illuminates the complex world of genetics in an engaging, lively manner. Codice libro della libreria ABE_book_new_0192860887
