  • Descrição: Throughout the Holocene occupation of the North American continent, residential mobility declined while plant domestication increased. Direct results of these processes have been investigated through structural, paleobotanical and ceramic analyses, but have rarely been detected in assemblages of stone tools. This study involves intensive technological and use-wear analyses of lithic materials from five excavated sites in the Illinois Valley that span 7,500 years of the Holocene. Results of functional trends analyzed through time indicate that most of the specific activities and worked materials in which the tools were engaged are stochastic in nature. Nevertheless, certain trends, including increases in the proportion of chopping/percussion damage and the presence of hoeing wear in later components, are consistent with changes in mobility and plant manipulation. The presence of other coeval processes is indicated by increases in wear from drilling and projectile use. In addition, support is found for the contention that highly mobile foragers of the Early Holocene needed standardized, multi-functional implements such as bifaces. The decline in bifacial technologies throughout the Holocene provides a measure of increasing sedentism, as considerations of versatility and portability were eschewed in favor of more expedient technologies.
