Scientists are using DNA analysis to understand our prehistory: the evolution of humans; their relation to the Neanderthals, who populated Europe and the Near East; and Homo erectus, who roamed the steppes of Asia. Most importantly, geneticists can trace the movements of a little band of human ancestors, numbering perhaps no more than 150, who crossed the Red Sea from east Africa about 50,000 years ago. Within a few thousand years, their descendents, Homo sapiens, became masters of all they surveyed, the other humanoid species having become extinct. According to New York Times science reporter Wade, this DNA analysis shows that evolution isn't restricted to the distant past: Iceland has been settled for only 1,000 years, but the inhabitants have already developed distinctive genetic traits. Wade expands his survey to cover the development of language and the domestication of man's best friend. And while "race" is often a dirty word in science, one of the book's best chapters shows how racial differences can be marked genetically and why this is important, not least for the treatment of diseases. This is highly recommended for readers interested in how DNA analysis is rewriting the history of mankind. Maps. (Apr. 24)

Genetics has been intruding on human origins research, long the domain of archaeology and paleoanthropology. Veteran science journalist Wade applies the insights of genetics to every intriguing question about the appearance and global dispersal of our species. The result is Wade's recounting of "a new narrative," which also has elements of a turf war between geneticists and their established colleagues. He efficiently explains how an evolutionary event (e.g., hairlessness) is recorded in DNA, and how rates of mutation can set boundary dates for it. For the story, Wade opens with a geneticist's estimate that modern (distinct from "archaic") Homo sapiens arose in northeast Africa 59,000 years ago, with a tiny population of only a few thousand, and was homogenous in appearance and language. Tracking the ensuing expansion and evolutionary pressures on humans, Wade covers the genetic evidence bearing on Neanderthals, race, language, social behaviors such as male-female pair bonding, and cultural practices such as religion. Wade presents the science skillfully, with detail and complexity and without compromising clarity. Gilbert Taylor
