Plan and Purpose in Nature is a brilliant survey of Darwinian evolution in the natural world. It tells the story not only of the wonderful adaptations which the process of the natural selection produces throughout nature,but also the limitations of evolution for the 20th century human beings,which environment and diet have changed drastically while their biology and psychology have not.
George C. Williams is recognized internationally as a leading authority in the study of evolutionary biology. His book Adaptation and Natural Selection , published in 1996, has had an enormous influence on evolutionary thinking. His other books include Sex and Evolution , Natural Selection: Domains, Levels and Challenge and (with Rudolph Nesse) Evolution and Healing: The New Science of Darwinian Medicine . Dr Williams is Professor Emeritus of Ecology and Evolution at the State University of New York.
