The Baldwin Effect has been explicitly used as an argument for the explanation of the origins of language and the evolution of a Language Acquisition Device (65). This paper presents new simulations of an artificial life model for the evolution of compositional languages (11). It specifically addresses the role of cultural variation and of learning costs in the Baldwin Effect for the evolution of language. Results show that when there is a high cost associated with language learning, agents gradually assimilate in their genome some explicit features (e.g. lexical properties) of the specific language they are exposed to. When the structure of the language is allowed to vary using a process of cultural transmission, Baldwinian processes cause, instead, the assimilation of a predisposition to learn, rather than any structural properties associated with a specific language. The analysis of the mechanisms underlying such a predisposition in terms of Categorical Perception (35), supports Deacon's hypothesis (24) regarding the Baldwinian inheritance of general underlying cognitive capabilities that serve language acquisition. This is in opposition to the thesis that argues for assimilation of structural properties needed for the specification of a fully blown Language Acquisition Device.
