Each of us begins our path in life as a single cell. Just thinking about this common process can fill us with a sense of wonder--and raise a host of questions. How does an egg cell multiply to develop into a human being, an animal, or a plant? How do cells form a brain, a face, a hand? And how does the pattern continue generation after generation? With great insight and unwavering enthusiasm, biology professor Lewis Wolpert presents this complex subject in a clear and engagingly written book (Nature) that even the layman can understand. Illuminating the subject with twelve remarkable full-page photographs and numerous informative illustrations, this landmark guide shows the separation, growth, and differentiation of various cells and body parts in the embryonic stage. Simple descriptions of Wolpert's experimental studies offer fascinating insights into topics such as aging, cancer, regeneration, and evolution. Addressing the mysteries that face modern biologists--and all of mankind--The Triumph of the Embryo is a fascinating read for anyone curious about the replication and development of life--(Science News). A new preface has been provided by the author.
