IN THIS ANTHOLOGY, Mark Raab and Terry Jones present a series of research articles that dispel lingering mythologies about California's prehistory. They begin with the most enduring notion--that of an essentially stable, benign climate--presenting evidence that prehistoric climate flux played a significant role in culture change. From there, Raab and Jones assault the myth of California as a natural cornucopia. They show that prehistoric foragers themselves had the capacity to negatively affect their animal food supplies, and that what is often considered the premier vegetal food, the acorn, appeared much later than many suppose in the diets of native peoples. This collection effectively summarizes the major debates surrounding California archaeology and provides a solid basis for a new, more nuanced view of the state's prehistory.
