"A wonderful, balanced, and accurate account of the search for the oldest human ancestors and the personages involved in this quest. Gibbons provides a revealing window into the house of horrors that can be human origins research."--Science"Thrilling.... Gibbons [writes] with great flair." --Entertainment Weekly"An entertaining, richly detailed story, told with clarity and a commanding grasp of the complexities of human origins."--The Plain Dealer"Colorful and readable. . . . Like a detective story that puts Sherlock Holmes, Hercule Poirot, Sam Spade, V.I. Warshawski, Easy Rawlins and Gil Grissom all in the same room, gives them a handful of clues, and lets them argue endlessly about the solution. Science writing is rarely this entertaining."--San Jose Mercury News
