Models can help to sharpen intuitions, reveal unexpected behaviours and test hypotheses, and are especially valuable when trying to understand past events where real time experiments are not possible, as is often the case in archaeology. In this study we develop a spatially-explicit agent-based cultural evolutionary simulation model to examine the extent to which mobility, population density and food income/health (as measured by non-cumulative food resource procurement in a single time step) are shaped by resource depletion and replenishment rates. Our model considers the feedback between people and their environment (as in27), and includes a culturally inherited and mutable mobility strategy, population growth, food income changes, and resource depletion and replenishment processes. It also includes movement decisions in an environment where resource availability varies (as in2,27,28).
