We've been under the spell of DNA for too long. Science historian and MacArthur Fellow Evelyn Fox Keller makes the case for radically new thinking about the nature of heredity in The Century of the Gene. This short, magisterial treatise examines 100 years of genetic thinking and finds outdated elements of Victorian beliefs still permeating our scientific writing. Despite compelling evidence that cytoplasmic and other nonchromosomal factors play important roles in development and even in the inheritance of traits, most discussion still relies on the master-slave (or manager-worker) relationship between the nucleus and the cell. Keller wants to move on; her proximate goal is to proceed from talking about genes to talking about genetic talk, the better to understand our biases. Her excitement at developments such as the Human Genome Project, despite her initial doubts, is only heightened by the prospect of vast stretches of uncharted intellectual territory. Ultimately, of course, her program matches that of the scientific enterprise--to more fully understand ourselves and our world. What comes after The Century of the Gene? It's an excellent question, and one that can only be answered once we leave behind the baggage of the past. --Rob Lightner
