Offering daring new ideas about evolution, two highly respected biologists here tackle the central, unresolved question in the field—how have living organisms on Earth developed with such astounding variety and complexity? Marc Kirschner and John Gerhart draw on cutting-edge biological and medical research to provide an original solution to this longstanding puzzle."In this terrific new book, molecular systems meet evolution. The result is a wealth of stimulating ideas set among clear explanations drawn from a revelatory decade in biology."—Andrew H. Knoll, author of Life on a Young Planet"Thought-provoking and lucidly written. . . . The Plausibility of Life will help readers understand not just the plausibility of evolution, but its remarkable, inventive powers." —Sean Carroll, author of Endless Forms Most Beautiful: The New Science of Evo Devo“Remarkably lucid and comprehensive, this new theoretical synthesis will . . . shift the grounds for debate in the controversy surrounding organic evolution.”—Booklist (starred review)
