ABSTRACT
In recent years, with the expansion of computer science, researchers in the cognitive sciences have been attracted towards the use of computational models for understanding the structure of human thought. Such work as has been done has proved extremely powerful for tackling contemporary situations (Haugeland 1985), and so it is appropriate to ask whether such approaches have the potential for explaining the evolutionary development of systems of human knowledge. In this chapter I shall examine how such knowledge systems may be structured, and whether there is evidence for their origins in human prehistory.
