摘要:T his book challenges longstanding assumptions about the colonization of the western hemisphere by focus- ing on the exploitation of marine environments as a con- tributory factor. Dennis Stanford, Curator of North Ameri- can Archaeology at the Smithsonian, and Bruce Bradley, Professor of Archaeology at the University of Exeter, are recognized experts in the field of Paleoindian archaeology and lithic technology. The book is well illustrated with nu- merous photographs and sketches, and the inclusion of vi- gnettes based on the authors' cumulative personal experi- ences lightens the heavier chapters, making the book quite readable.
