- From Michael Crichton, the #1 bestselling author of Jurassic Park and The Andromeda Strain, comes an astounding, eye-opening look at the world of genetics: Next. Is a loved one missing some body parts? Are blondes becoming extinct? Is everyone at your dinner table of the same species? Humans and chimpanzees differ in only 400 genes; is that why a chimp fetus resembles a human being? And should that worry us? There"s a new genetic cure for drug addiction - is it worse than the disease? Devilishly clever, Next blends fact and fiction into a breathless tale of a new world where nothing is what it seems, and genetic ownership shatters our assumptions.
