Another Look at Expedient Technologies, Sedentism, and the Bow and Arrow

The transition from the dart to the arrow, and the commensurate changes in lithic technology is poorly understood in the American Southwest. This transition has often been linked to shifts in sedentism and the increasing use of expedient flake tools. However, the relationship between the use of bifacial and core reduction strategies are conditioned by a variety of factors, and not primarily in response to the use of the bow-and-arrow, or simply sedentism. We, therefore, evaluate a series of potential factors which can be used to understand the variability exhibited in the use of biface and flake technologies.
