Social learning and evolution in a structured environment

Abstract

We survey the relationships between evolution, individual learning and social transmission within well-mixed and structured environments.With a novel individual-based simulation, we determine the regimes under which each mode of learning dominates, in terms of the environment's relative complexity and its rate of change.We show that social learning can give rise to a particularly potent form of the "Baldwin effect", wherein an organism develops an innate trait having first acquired it socially.We demonstrate that social learning is of increased significance in a structured environment.
