The authors use a comparative ethnoarchaeological model that seeks to test the applicability of Dynamical Systems Theory to modeling subsistence variation (namely the foraging-farming transition). The authors utilize the concepts of "attractors," which tend to stabilize a system, and "repellors," which tend to be destabilizing forces. Authors hope that this multidimensional approach, which assumes that several "controlling" variables disproportionately affect change within subsistence systems, will adequately model the nonlinearity and heterogeneity seen in the emergences of (and variations within) human subsistence systems throughout human history. Their model and premises regarding disproportionally-controlling variables appear to be supported.
