Surf & Turf: The role of intensification and surplus production in the development of social complexity in coastal vs terrestrial habitats

Social complexity in coastal and terrestrial environments both emerge as forms of subsistence intensification on previous foraging patterns but take different trajectories because of differences in the spatial and temporal structure and density of harvestable biomass between the two ecozones. Norms and values surrounding standards of living motivate households to intensify production above what is needed for mere survival (i.e., surplus), which in turn has the effect of providing a buffer against unpredictable shortfalls and longer-term population-resource imbalances caused by population growth. Economies of scale introduced by increasing labor group size and differentiation as well as technology fund the production and consumption of surplus and drive the emergence of social complexity among foragers and cultivators alike.
