"I've read the entire volume, word for word, in part because I continue to learn new things from every revision of Wenke's work. It continues to be the best introductory book on world prehistory on the market. The text is easily accessible and serious at the same time, and I highly recommend it for courses that are designed as overviews of the emergence of modern humans as a biological and social species."--Terence N. D'Altroy, Columbia University
