Synopsis
Is human behavior genetic? Do we inherit our intelligence, our sexuality, our predispositions to illness or depression, or our particular talents through our genes? Newspaper headlines today tout genetic explanations of everything from cancer to alcoholism and criminality. But as Exploding the Gene Myth demonstrates, such explanations are nearly always exaggerated or unfounded, ignoring the complex interactions of genes with environment at every level. Like the eugenic theories of seventy-five years ago, the new genetic determinism serves a conservative social agenda, reflecting our society's eagerness to blame ill health and misfortune on individuals rather than on social and environmental conditions.
Exploding the Gene Myth explains in clear, accessible language how genes really work. Ruth Hubbard and Elijah Wald then evaluate the tremendous impact of genetic information on how we are treated by doctors and health insurance companies, by schools, by the criminal justice system, and by potential employers.
The authors are especially critical of the multi-billion-dollar Human Genome Initiative, the huge research project to map every gene on the DNA of a prototypical human being. Hubbard and Wald deflate the grandiose promises of therapeutic benefits that are supposed to emerge from the project. They point instead to the real threats to privacy and civil liberties already resulting from the unregulated increase in genetic predictions.
At a time when the biosciences are undergoing a revolution, the enthusiasm of scientists and the media about new genetic information and technologies needs to be tempered with realism. Hubbard and Wald argue that all citizens, not just scientists, should be able to participate in making the necessary decisions about how to regulate information, protect privacy, and avoid discrimination. Exploding the Gene Myth is a forceful plea for a society that would invest in safe, healthful living and working conditions for everyone rather than the search for ideal or improved genes.
Reviews
Harvard biologist Hubbard and freelance writer Wald are leading critics of "the myth of the all-powerful gene." In a hard-hitting critique of genetic determinism and biotechnology, they attack scientists who cite DNA sequences as the presumed basis for a genetic tendency to cancer, high blood pressure, alcoholism and criminal behavior. Such researchers are guilty of leaps of faith and logic, charge the authors. Arguing that genetic screening tests may increase discrimination against people with perceived shortcomings, Hubbard and Wald criticize the Human Genome Project, whose goal is to map the entire sequence of the three billion DNA and RNA subunits that make up our genes. Claims that this project will lead to cures for a wide range of diseases are unfounded, contend the authors. They demonstrate that DNA matching or "fingerprinting," touted by criminal prosecutors as a foolproof forensic tool, is actually fallible. Their expose of the fallacies and pitfalls of genetic testing in schools, the workplace, and by doctors and insurance companies makes this an important handbook.

Harvard biologist and feminist Hubbard and her son (as well as her Nobel laureate husband, George Wald) have long championed the antibiotechnology cause, raising the specter of genetic determinism, eugenics, and social control (read ``fascism'') that they see as imminent in genetics research. Their point of view is that of old-fashioned liberals, winning praise from the Richard Lewontins, Barry Commoners, Ralph Naders, and other defenders of the common man (and woman) and the natural environment against government bureaucrats, scientific reductionists, and others viewed as profiteers or manipulators and exploiters of humankind. In so doing, the authors serve a corrective function, offering the kind of countervailing sensibility that's so important in a democratic society. But, here, they go too far in their zeal, discounting the value of much genetics research and of the human genome project in particular. Certainly, we need safeguards regarding the collection and use of genetic data to prevent discrimination and abuses in education, employment, and insurance, as well as to prevent gene testing for such arbitrary purposes as sex selection and so on. But to deny the importance of genetic research in finding clues to development and aging, plus the causes and cures of disease, is to throw the baby out with the bathwater. Interestingly, in contrast to Andrew Kimbrell in The Human Body Shop (reviewed below), Hubbard and Wald disavow claims that genes have been (or will be) discovered for intelligence, homosexuality, alcoholism, etc.; meanwhile, Kimbrell acts as though such putative genes will determine how we select offspring in the future. The moral of the story is that the pendulum swings both ways, but the truth lies somewhere in the middle. (Seven illustrations) -- Copyright ©1993, Kirkus Associates, LP. All rights reserved.
