Using a mathematical model, researchers have shed new light on the transition from hunter-gatherer to farming societies. Rather than focusing exclusively on external factors, they looked at internal demographics and the significant impact of human interactions. The model identified potential societal outcomes based on demographic changes, emphasising aspects such as migration rates, cultural assimilation and the role of mortality in these transitions. The researchers aim to further develop their model with the aim of making it a standard tool for studying historical demographic interactions.
