A masterful guide to human development that redefines the nature versus nurture debate A much-needed antidote to genetic determinism, The Dependent Gene reveals how all traits-even characteristics like eye and hair color-are caused by complex interactions between genes and the environment at every stage of biological and psychological development, from the single fertilized egg to full-grown adulthood. How we understand the nature versus nurture debate directly affects our thoughts about such basic issues as sex and reproduction, parenting, education, and crime, and has an enormous impact on social policy. With life-and-death questions in the balance surrounding stem-cell research, cloning, and DNA fingerprinting, we can no longer afford to be ignorant of human development. An enlightening guide to this brave new world, The Dependent Gene empowers us to take control of our own destiny. "A provocative and gracefully written book that will surely generate discussion and debate." -Jerome Kagan, Ph.D., author of Three Seductive Ideas " The Dependent Gene is a masterful analysis. A useful and engaging guide for the lay reader, the practicing scientist, and all who seek a more integrative approach to the endlessly fascinating process of development." -Robert Lickliter, Virginia Polytechnic Institute and State University
