"This book is an extraordinary integration of a lifetime of thought on the subject by an exceptional scholar. Morowitz logically, consistently, and persuasively moves to define arguments that will influence thought in a fundamental realm of biology." -Donald M. Engelman, Yale University "Morowitz develops a model of the origin of life in which cells originate first, proteins follow, and genes evolve last. This model contradicts conventional wisdom but has the distinct advantage of being testable; and is supported by evidence mustered from biology, biochemistry, and biophysics. Morowitz['s] expertise in all three disciplines is impressive."-Francisco J. Ayala, Dept. of Ecology and Evol. Biology, University of California, Irvine "In this short and clearly written book, Morowitz explores the origins of life. . . . His objective is elegantly achieved. . . . A stimulating analysis . . . [and] an excellent read." -A. E. Douglas, Times Higher Education Supplement "[A] book rich in provocative and stimulating ideas. . . . I recommend it to anyone who has ever thought seriously about the origin of life." -Vincent P. Cirillo, Quarterly Review of Biology
