E.O. Wilson defines sociobiology as "the systematic study of the biological basis of all social behavior," the central theoretical problem of which is the question of how behaviors that seemingly contradict the principles of natural selection, such as altruism, can develop. Sociobiology: A New Synthesis, Wilson's first attempt to outline the new field of study, was first published in 1975 and called for a fairly revolutionary update to the so-called Modern Synthesis of evolutionary biology. Sociobiology as a new field of study demanded the active inclusion of sociology, the social sciences, and the humanities in evolutionary theory. Often criticized for its apparent message of "biological destiny," Sociobiology set the stage for such controversial works as Richard Dawkins's The Selfish Gene and Wilson's own Consilience. Sociobiology defines such concepts as society, individual, population, communication, and regulation. It attempts to explain, biologically, why groups of animals behave the way they do when finding food or shelter, confronting enemies, or getting along with one another. Wilson seeks to explain how group selection, altruism, hierarchies, and sexual selection work in populations of animals, and to identify evolutionary trends and sociobiological characteristics of all animal groups, up to and including man. The insect sections of the books are particularly interesting, given Wilson's status as the world's most famous entomologist. It is fair to say that as an ecological strategy eusociality has been overwhelmingly successful. It is useful to think of an insect colony as a diffuse organism, weighing anywhere from less than a gram to as much as a kilogram and possessing from about a hundred to a million or more tiny mouths. It's when Wilson starts talking about human beings that the furor starts. Feminists have been among the strongest critics of the work, arguing that humans are not slaves to a biological destiny, forever locked in "primitive" behavior patterns without the ability to reason past our biochemical nature. Like The Origin of Species, Sociobiology has forced many biologists and social scientists to reassess their most cherished notions of how life works. It's been 25 years since E. O. Wilson wrote Sociobiology, naming a new science and starting it off with a bang--and a firestorm of protest. "Nurture!" and "Nature!" came the cries from every corner of the academic world, as the book became a causus belli for sociologists, feminists, human geneticists, and psychologists. --Mary Ellen Curtin (amazon.com ) This book enthralls and enchants...If you have this book...you can begin getting your mind ready for the illuminations about human society. --Lewis Thomas (Harper's ) Rarely has the world been provided with such a splendid stepping stone for an exciting future of a new science. --John Tyler Bonner (Scientific American ) Its contents do indeed provide a new synthesis, of wide perspective and great authority...Wilson's plain uncluttered prose is a treat to read, his logic is rigorous, his arguments are lucid. --V. C. Wymne-Edwards (Nature ) This book will stand as a landmark in the comparative study of social behavior. (Quarterly Review of Biology ) Sociobiology is an excellent book, full of extraordinary insights, and replete with the beauty and poetry of the animal kingdom. (Times Literary Supplement ) It is impossible to leave Wilson's book without having one's sense of life permanently and dramatically widened. --Fred Hapgood (The Atlantic )
