In July 1996, Dr. Ian Wilmut used an electric charge to bring dormant cells to life, and from these cells a sheep named Dolly—the world’s first cloned mammal—was created. In this program, Michael McClure of the National Institutes of Health begins by tracing the history of such genetic reproduction technology as in vitro fertilization, parthenogenesis, and genetic therapy—antecedents of modern cloning practices. Computer graphics then illustrate the biomechanics of cloning. Cloning’s implications for biology, medicine, and agriculture are discussed. Dr. Ruth Macklin of the Albert Einstein College of Medicine discusses the possible role of cloning in the prevention of extinction, the creation of "super" breeds of animals, the curing of disease, and the growth of human organs needed for transplant. A panel of experts discusses the future of cloning and possible abuses. (25 minutes)
