“Concept “Out of Africa” by means of Agent-based Modeling (ABM)”
My work is focused on hominin dispersal and the processes that are involved. Hominin dispersal is not only driven by changes in the environment but also a result of a chain of active decision making. Agent-based modeling is best suited for modeling the interaction between a population and its environment which we think is a driving factor for hominin dispersal. A prominent example is “Out of Africa”. There are currently four possible routes for the human dispersal out of Africa, via the Bab al Mandab Route, along the Levantine Corridor, the Sicily Route and/or the Gibraltar Route. Several hypotheses may play a role for the hominin dispersal such as ecological variations, demographic pressure, climatic changes, biological and social organization, dispersal of megafauna, carnivore competition, vegetation and sea-level changes. With Agent-based modeling we can develop, test and compare different scenarios that include all the mentioned hypotheses.
