The story of a biologist's search for the foundations of behavior. Looking over the shoulder of some of the premier scientists in the field, biologist Weiner takes us into their laboratories to show us how pieces of DNA actually shape behavior. He focuses on the work of Seymour Benzer, who, decades ago, with James Watson and Francis Crick, helped to crack the genetic code. Then, in a simple experiment using a few test tubes, a light bulb, and 100 fruit flies, Benzer invented the genetic dissection of behavior. Now we see how he and his students find and study genes that build our inner clocks, genes that shape the way we love, and genes that decide what we can (or cannot) remember. These breakthroughs help explain secrets of human behavior and may lead to advance treatments for behavioral disorders ranging from rage to autism to schizophrenia.--From publisher description.
