How Learning and Evolution Interact: The Case of a Learning Task which Differs from the Evolutionary Task

Institute of Psychology, National Research Council, Rome

It has been reported recently that learning has a beneficial effect on evolution even if the learning involved the acquisition of an ability which is different from the ability for which individuals were selected (Nolfi, Elman & Parisi, 1994). This effect was explained as the result of the inter action between learning and evolution. In a successive paper, however, the effect was explained as a form of recovery from weight perturbation caused by mutations (Harvey, 1996, 1997). In this paper, I provide additional data that show how the effect, at least in the case considered in the paper, can only be explained as a result of the interaction between learning and evolution as originally hypothesized.

Key Words: evolution • learning • Baldwin Effect.
