Randolph M Nesse, M.D., is a practicing physcian and professor and associate chair for education and academic affairs in the Department of Psychiatry at the University of Michigan Medical School. George C. Williams, Ph.D., is a professor emeritus of ecology and evolution at the State University at Stony Brook and editor of The Quarterly Review of Biology.
Nesse and Williams have written a lively discourse on the application of the principles of evolutionary biology to the dilemmas of modern medicine. Nesse, a physician and an associate professor of psychiatry, and Williams, a professor of ecology and evolution, provide a primer on Darwin's theory of natural selection. They explain that the functional design of organisms-e.g., our bodies-may suggest new ways of addressing illness. The book begins with a look at the causes of disease and their evolutionary influences. But the book mainly assesses the concept of adaptation by natural selection, and illustrates the ways Darwinian thinking can be applied to medical problems. As one example, the authors examine the use of penicillin over the past 60 years against bacterial infections. The book's quirky information may speak to a broad audience: researchers, for instance, have found that relatives of schizophrenics have an unusually high frequency of inclusion in Who's Who-which may counterbalance drawbacks of the disorder in evolutionary terms. The tendency toward child abuse, too, may be influenced, the authors say, by evolution and the passing on of genes. And there may well be an evolutionary reason to welcome morning sickness, they argue: nausea and food aversions during pregnancy apparently evolved to impose dietary restrictions on the mother so as to correspond with fetal vulnerability and, thereby, minimize fetal exposure to food toxins.

"By bringing the evolutionary vision systematically into one of the last unconquered provinces, Nesse and Williams have devised not only means for the improvement of medicine but fundamental new insights into the human condition."--Edward O. Wilson, Harvard University
"In moving the focus from 'how' to 'why' questions, Nesse and Williams introduce readers to a new way of thinking about illness, one that promises to be of increasing interest as...our culture turns toward evolutionary explanations for human predicaments."--Peter D. Kramer, author of Listening to Prozac
Offering new insights on the failure of evolution to eradicate disease, psychiatrist Nesse and ecologist Williams offer numerous suggestions on why certain seemingly negative traits have not been eliminated through natural selection. A brief discussion of the basics of evolution is provided, along with examples of how the theory of natural selection may relate to aging, cancer, allergies, and other diseases. One particularly intriguing chapter is devoted to the possibility of an evolutionary contribution to psychological disorders such as excessive anxiety or depression. Marc Lappe's recent Evolutionary Medicine: Rethinking the Origins of Disease (LJ 10/15/94) conveys a similar message on the increasing need to consider evolutionary principles in the treatment of disease. Both books are thought-provoking and worthy purchases, but librarians interested in a slightly less technical narrative may prefer Why We Get Sick.-Tina Neville, Univ. of South Florida at St. Petersburg Lib.
