In Plan and Purpose in Nature George C. Williams examines Darwinian evolution in the natural world. He tells the story not only of adaptations which natural selection produces through nature, but also the limitations of evolution for modern human beings, and how the rapid evolution of micro-organisms is likely to pose an alarming threat to human health.

A leading evolutionary thinker, biologist, and medical researcher asks the question: "Could life elsewhere be substantially different from life on Earth?"--and builds a step-by-step argument for human inevitability. 65 illustrations and photos.

Within the natural sciences, only biologists take seriously teleological statements about design, purpose and adaptive function. Some biologists claim that to understand the complex morphological and behavioural traits of organisms we must say what they are for, which is to give a teleological explanation of why organisms have them. Others argue that the theory of natural selection, in providing statistical explanations for the same phenomena, obviates any need for teleological thinking. If teleology cannot be eliminated from biology, it raises fundamental questions about the nature of biological explanation and about the relationship of biology to the rest of science.

"Highly informative and remarkably entertaining." —Elle From forest trails in Korea, to islands in Finland, to eucalyptus groves in California, Florence Williams investigates the science behind nature’s positive effects on the brain. Delving into brand-new research, she uncovers the powers of the natural world to improve health, promote reflection and innovation, and strengthen our relationships. As our modern lives shift dramatically indoors, these ideas—and the answers they yield—are more urgent than ever.

Faced with the ceaseless stream of news about war, crime, and terrorism, one could easily think this is the most violent age ever seen. Yet as bestselling author Pinker shows in this startling and engaging new work, just the opposite is true.
