As Kenneth Kennedy writes, Roger Lewin is "one of the very few scientific journalists I know who has been successful in relating, with accuracy and an exciting writing style, the principles of paleoanthropology to a broad reading audience of scholars and laymen." Unsurprisingly, then, his Human Evolution is a good introduction to its subject. Containing brief but accurate accounts of contemporary research and results, as well as copious references and illustrations, it is eminently useful both as a general source of information and as a supplementary textbook. Lewin's other books include Bones of Contention and (with Richard Leakey) Origins Reconsidered.
