A technological change from formal to expedient core reduction marks the “transition” from mobile to sedentary prehistoric societies in many parts of the world. The phenomenon has often been attributed to changes in the organization of men's activities, particularly hunting. Considering, however, that the change coincides with the adoption of pottery, technology usually attributed to women, an alternative explanation must be considered. From the standpoint of archaeological systematics, the addition of pottery turns our focus away from places where hafted bifaces were discarded toward places where pottery was discarded. The latter are largely domestic contexts: locations at which women, as well as men, employed expedient core technology for a variety of tasks. Thus, the perceived change in core technology reflects the increased visibility of women's activities in the archaeological record. This recognition provides a basis for incorporating gender variables into our interpretations of prehistoric technology and labor organization.
