It Ain't Necessarily So: The Dream of the Human Genome and Other Illusions

Richard C. Lewontin. New York Review of Books, $24.95 (330pp) ISBN 978-0-940322-10-3

Harvard biologist Lewontin is highly skeptical of the human genome project supporters' claims that complete knowledge of the human organism and effective gene therapies are just around the corner. His forceful critique of this multimillion-dollar gene-mapping project points out that our DNA is infinitely complex, and that mutations in genes are not the cause of, say, cancer, although they may be one of many predisposing conditions. In a bracing, lucid collection of essays, all originally published in the New York Review of Books, Lewontin makes bold forays into such fields as evolutionary theory, IQ testing, criminology, artificial intelligence, neurobiology and gender differences, exposing sloppy thinking and fallacies on all fronts. Scrutinizing ""the development of modern biology from Darwin to Dolly"" (a reference to the sheep cloned in 1997), Lewontin lambastes Clinton's National Bioethics Advisory Commission, charging that its report on the possibility of human cloning sidestepped fundamental ethical, religious and political issues. Lewontin is a formidable critic of simplistic, flawed biological determinism, which he sees at work in studies of identical twins reared apart; in feminist biologists' claim that females are the smarter, gentler, more humane sex; in sociobiologist E.O. Wilson's belief that the sexual division of power flows directly from innate differences between men and women; and in biologist Richard Dawkins's argument for the primacy of genes over the social environment. Several of these rigorous essays include an exchange of letters between Lewontin and his critics, making this an illuminating forum of ideas. (May)
