A Dan Josselyn Memorial Publication Specialists from archaeology, ethnohistory, physical anthropology, and cultural anthropology bring their varied points of view to this subject in an attempt to answer basic questions about the nature and extent of social change within the time period. The scholars' overriding concerns include presentation of a scientifically accurate depiction of the native cultures in the Central Mississippi Valley prior and immediately subsequent to European contact and the need to document the ensuing social and biological changes that eventually led to the widespread depopulation and cultural reorientation. Their findings lead to three basic hypotheses that will focus the scholarly research for decades to come. Contributors include: George J. Armelagos, Ian W. Brown, Chester B. DePratter, George F.
