Grade 8 Up—The origin of the human species is always a topic of educational inquiry as well as fierce debate. Providing students with information that is credible, detailed, and appealing can be challenging: these books exceed the challenge. Stefoff provides an enlightening and entertaining history of the evolution of Homo sapiens, their ancestors, and cousins, from primitive origins to today. The clear, insightful texts are accented by intriguing sidebars and colorful photos, maps, and graphs. The author provides compelling details from the lives of innovators such as Darwin and Leaky, intelligently discusses the tools of the trade, and deftly explores many monumental discoveries, such as those of Australopithecus in 1924 (First Humans) and the Old Man of La Chapelle in 1908 (Ice Age Neanderthals), and of a "family tree" for mitochondrial DNA (Modern Humans).
