“The scientific discoveries described in this book may turn out . . . to have been the most important research findings in the long history of science.” ―Lewis Thomas, from the Foreward The Cold and the Dark is the record of the Conference on the Long-Term Worldwide Biological Consequences of Nuclear War, held in Washington, D.C., on October 31 to November 1, 1983. The conference involved over 200 scientists from many nations and drew together the best available scientific information. Its central finding was the phenomenon of nuclear winter: a much more profound and long-lasting devastation of the earth and atmosphere than had been believed possible before. In the two principal papers, Carl Sagan presents the atmospheric and climatic consequences of nuclear war and Paul Ehrlich summarizes its biological implications. Also included is the text of the “Moscow Link” ―a dialogue between Soviet and American scientists on nuclear winter―and the technical papers providing the scientific evidence for the book’s conclusions.

There's a silent epidemic in western civilization, and it is right under our noses. Our jaws are getting smaller and our teeth crooked and crowded, creating not only aesthetic challenges but also difficulties with breathing. Modern orthodontics has persuaded us that braces and oral devices can correct these problems. While teeth can certainly be straightened, what about the underlying causes of this rapid shift in oral evolution and the health risks posed by obstructed airways? Sandra Kahn and Paul R. Ehrlich, a pioneering orthodontist and a world-renowned evolutionist, respectively, present the biological, dietary, and cultural changes that have driven us toward this major health challenge. They propose simple adjustments that can alleviate this developing crisis, as well as a major alternative to orthodontics that promises more significant long-term relief. Jaws will change your life. Every parent should read this book.
The author, a prominent evolutionary biologist, challenges the notion of genetic destiny by highlighting misconceptions about evolution. Through clear explanations and illustrations, the book delves into the complexities of genetic influence and emphasizes the limitations of deterministic views on genetics. It aims to reshape the reader's understanding of evolution and its implications for human behavior and identity.
