The triple helix: gene, organism, and environment

Lewontin, Richard
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.

Of flies, mice, and men

Jacob, François
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.
