THE THIRD DOMAIN: The Untold Story of Archaea and the Future of Biotechnology TIM FRIEND

Until 1977, the known classes of life included eukaryotes and bacteria. When microbiologist Carl Woese announced the discovery of a third class, most academics scoffed. Yet today, barely 30 years later, archaea are known to be at least as abundant as bacteria. They are among the oldest life forms on Earth. These hardy organisms are capable of surviving within the harshest conditions, from volcanic mud to deep-ocean sediments. Friend, a science writer for USA Today, examines the implications of Woese's discovery on microbiology, genetics, and studies of the origin of life, In a book that is based in part on lab visits, treks to hot springs, and interviews with members of undersea-expedition teams, Friend chronicles scientists' efforts to decode archaea's genetics and to unlock the secrets of its amazing survival skills. Joseph Henry Press, 2007, 296 p., b&w plates, hardcover, $27.95.
