Intended as a companion volume to the newly opened Hall of Human Biology and Evolution at the American Museum of Natural History, this book stands well alone. Opening chapters survey life's diversity, highlight human biological systems, and define the place of humankind within the animal kingdom. Upon this foundation, Tattersall--a noted anthropologist and a curator at the museum--interweaves information on fossil finds, artifacts, climate, geology, biology, and sociology to create a vivid depiction of the evolution of primates into Homo sapiens . Current mainstream opinions, alternate views, and earlier theories are explained in a well-balanced fashion. The addition of top-quality photos, maps, charts, and artist's reconstructions makes for an inviting package accessible to both young adult and lay readers. The result is similar in scope and quality to Roger Lewin's In the Age of Mankind: A Smithsonian Book of Human Evolution ( LJ 12/88). Highly recommended for general collections.-- Frank Reiser, Nassau Community Coll., Garden City, N.Y.
