Broad Spectrum Revolution (Other Keyword)
1-3 (3 Records)
Widely accepted models for the diversification of subsistence economies that preceded the domestication of plants and animals in the Near East frame this key transition in the context of demographically induced resource pressure following a diet breadth model of forager decision making. Many of the supporting arguments for this scenario are open to an alternative view that casts these developments within the context of resource abundance and enhanced predictability. Contrasting explanatory...
Forager Efficiency, Demographic Shift and Environmental Change: Re-evaluating the Broad Spectrum Revolution in Mainland Southeast Asia (2015)
On the Thai-Malay Peninsula the Pleistocene to Holocene transition was accompanied by significant post-glacial sea level rise, new environmental conditions, and increased human population densities. How did foragers adapt to these changes? In this region, the BSR has been the primary framework for understanding forager response to these conditions since Gorman’s analysis of the fauna from Spirit Cave (1971). Gorman suggested, following Flannery’s in the Near East, that at the...
OFT, BSR, and JOC: James O’Connell’s Contributions to Understanding Broad Spectrum Economies Using Foraging Theory (2015)
O’Connell (JOC) was among the first to recognize the potential of optimal foraging theory (OFT) as a research strategy for investigating the Broad Spectrum Revolution (BSR). His work in Australia carried profound implications for the BSR that stimulated research particularly in the Great Basin and Australia. Although testing predictions in the archaeological record has proved challenging, these studies revealed aspects of the BSR not anticipated by simple foraging models. Recently, the...
