When naive foragers are introduced due to population turnover, and these follow the group, they end up spending time in patches that are already preferred by experienced foragers. As a result, their development is biased towards resources that the group already consumes. Since familiarity and preference are self-reinforcing (also emergent in the model) the young foragers could end up developing the same preference biases and so can end up inheriting their group’s behavioral repertoire . If behavioral repertoires are unique to a given group and persist across generations, then this can be seen as traditional differences between groups or cultural variation.
