Addresses the fundamental question of what it means to be alive from the perspective of a microbe, E. coli, that exists within all human beings, examining the germ's evolution and its important role in the history of biology.

One of our most brilliant evolutionary biologists, Richard Lewontin has also been a leading critic of those-scientists and non-scientists alike-who would misuse the science to which he has contributed so much. In The Triple Helix , Lewontin the scientist and Lewontin the critic come together to provide a concise, accessible account of what his work has taught him about biology and about its relevance to human affairs. In the process, he exposes some of the common and troubling misconceptions that misdirect and stall our understanding of biology and evolution. The central message of this book is that we will never fully understand living things if we continue to think of genes, organisms, and environments as separate entities, each with its distinct role to play in the history and operation of organic processes. Here Lewontin shows that an organism is a unique consequence of both genes and environment, of both internal and external features. Rejecting the notion that genes determine the organism, which then adapts to the environment, he explains that organisms, influenced in their development by their circumstances, in turn create, modify, and choose the environment in which they live. The Triple Helix is vintage Lewontin: brilliant, eloquent, passionate, and deeply critical. But it is neither a manifesto for a radical new methodology nor a brief for a new theory. It is instead a primer on the complexity of biological processes, a reminder to all of us that living things are never as simple as they may seem.

Who could have guessed that the lowly fruit fly might hold the key for decoding heredity? Or that the mouse might one day disclose astonishing evolutionary secrets? In a book infused with wisdom, wonder, and a healthy dose of wry skepticism, Nobel Prize-winning geneticist François Jacob walks us through the surprising ways of science, particularly the science of biology, in this century. Of Flies, Mice, and Men is at once a work of history, a social study of the role of scientists in the modern world, and a cautionary tale of the bumbling and brilliance, imagination and luck, that attend scientific discovery. A book about molecules, reproduction, and evolutionary tinkering, it is also about the way biologists work, and how they contemplate beauty and truth, good and evil. Animated with anecdotes from Greek mythology, literature, episodes from the history of science, and personal experience, Of Flies, Mice, and Men tells the story of how the marvelous discoveries of molecular and developmental biology are transforming our understanding of who we are and where we came from. In particular, Jacob scrutinizes the place of the scientist in society. Alternately cast as the soothsayer Tiresias, the conscienceless inventor Daedalus, or Prometheus, conveyer of dangerous knowledge, the scientist in our day must instead adopt the role of truthteller, Jacob suggests. And the crucial truth that molecular biology teaches is the one he elaborates with great clarity and grace in this book: that all animals are made of the same building blocks, by a combinatorial system that always rearranges the same elements according to new forms.

Selected by his daughter, Vivien, from Max Perutz's voluminous correspondence, the letters reproduced here portray their author with a spontaneity and directness no autobiography could have matched. They chronicle Perutz's adventurous life through his own vivid, erudite and humorous pen, documenting the hopes, roadblocks and moments of elation of his sixty-year quest to understand the molecular biology of hemoglobin. The first great step in this quest ― unraveling the molecular structure of hemoglobin ― earned Perutz the 1962 Nobel Prize in Chemistry. Narrated against a backdrop of family and friends, politics and war, literature, travels, and Max's beloved mountains, these letters provide rare insight into the thoughts of a remarkable and very human scientist, and delightful sketches of some of the people he encountered. Starting with lively letters to a girlfriend written in his youth in Vienna and the impressions of a young scientist in Cambridge, the letters progress to the desperate pleas of an "enemy alien" interned in Canada during World War II. The diary of Perutz's subsequent super-secret war work for the British to build a floating ice airstrip in the North Atlantic, ardent campaigning letters to scientists and politicians, and self-deprecating stories of his own mishaps written to amuse his children and grandchildren are some of the many highlights of these fascinating letters, unique in the annals of recent scientific history. This book is a companion to Georgina Ferry's Max Perutz and the Secret of Life. Together these volumes provide a portrait of an extraordinary character in the development of molecular biology.
