"With the Discovery of the double helix a generation ago, it was inevitable that we would ask new questions about the origins of behavior - animal and human. How much of our fate is decided before we are born? What is written and in what code? What chain of reactions leads from a twisted strand of DNA to a raucous laugh? To a thought? To a memory? To a head turning toward the light? To the habit of frowning? To a raised hand - or a raised wing?"--BOOK JACKET. "The man who has given us our first concrete and often astonishing answers is the maverick scientist Seymour Benzerone of the greatest biologists of the century. His early work on the gene helped transform biological research, and the experiments that he began at the California Institute of Technology - experiments that are, like Benzer himself, at once whimsical, serious, and highly original - are now transforming the study of genes and behavior."--BOOK JACKET. "In this book, Jonathan Weiner tells the story of Benzer and his work."--BOOK JACKET.
