Genetic Engineering (Genetics and Evolution)

Scientists are learning to manipulate the genes of plants and animals, changing existing organisms and creating new ones. By taking control of the mechanisms that govern heredity in other species, humans are actively directing their own evolution. Breakthroughs have come so quickly that many people find them strange and frightening. "Genetic Engineering" traces the history of genetic science up to the present day and proposes some thoughts about how it is likely to affect the future.
