Abstract
Evolutionary theory and terminology are widely used in recent archaeological work, and many evolutionary archaeologists have argued that the integration of such theory and terminology is essential to the future of our field. This paper considers evolutionary archaeology from two perspectives. First, it examines substantive claims that archaeology can study the operation of Darwinian evolution, either through a reliance on optimal-foraging theory or by linking the process of natural selection to archaeological data. It concludes that there are serious problems with both of these claims on Darwin: the relation between evolution and foraging theory has never been documented, and midrange arguments linking selection and archaeological data are unsustainable. Second, it argues that archaeologists rely metaphorically on evolutionary terminology to help make sense out of archaeological data. Although the use of evolutionary metaphor can be, and has been, problematic, it also offers a powerful conceptual framework for our research. However, this framework is only of one of a number of comparable frameworks that have been offered to our field, as a comparison of systems archaeology and evolutionary archaeology shows.
