A lively debate is shaping up between environmentalists and geneticists. Environmentalists, pointing to an important new study, say that deviations from the genetic norm are too small to matter in determining, for example, whether or not you will be diabetic. If true, this must make environmental causes, like what you eat, proportionally much more important. Genetic medicine begs--loudly!--to differ. We hear from both sides.
