A major global climate event called the Younger Dryas dramatically affected local environments and human populations at the end of the Pleistocene. This volume is the first book in fifteen years to comprehensively address key questions regarding the extent of this event and how hunter-gatherer populations adapted behaviorally and technologically in the face of major climatic change. An integrated set of theoretical articles and important case studies, written by well-known archaeologists, provide an excellent reference for researchers studying the end of the Pleistocene, as well as those studying hunter-gatherers and their response to climate change.
