Ethnographers have recently debated two distinct models of hunter-gath
erer and agriculturalist interaction in the tropical forests of island
Southeast Asia: (1) the 'Isolate' Model, proposing that hunter-gather
ers had a social network and stable, tropical forest-based foraging ec
onomy largely independent of contact with sedentary farmers until the
historic era, and (2) the 'Interdependent' Model, suggesting a lengthy
history of symbiotic exchange and economic overlap between the two po
pulations. While these models have been examined and debated from the
perspective of ethnohistoric and linguistic data, relevant archaeologi
cal evidence has been lacking. This paper uses archaeological data on
settlement patterns, lithic assemblage composition and the regional ci
rculation of ceramics, metal, and other trade goods to demonstrate tha
t the types of economic interactions suggested by the 'Interdependent'
Model have existed between lowland agriculturalists and upland forage
rs in the Tanjay Region of the Central Philippines for at least the la
st 1500 years.
