Archaeological investigations in the Lunsemfwa Drainage Basin of Zambia have yielded evidence that necessitates modification of current views about the nature of culture contact between hunter-gatherers and agriculturalists. Hypotheses of barter, theft or some kind of exchange network between the two communities are not supported. It is suggested that stone-tool-using foragers collected pottery from abandoned village sites and transported these back to their base camps. This hypothesis recognizes the significance of resource availability and of patterns of exploitation and settlement. Lack of regular contact during the period of co-existence was largely due to the environmental diversity of the region: the two populations occupied and utilized different areas and did not compete for the same resources.
