Abstract. This paper describes a model for the evolution of communication systems using simple syntactic rules, such as word combinations. It also focuses on the distinction between simple word­object associations and symbolic relationships. The simulation method combines the use of neural networks and genetic algorithms. The behavioral task is influenced by Savage­Rumbaugh & Rumbaugh's (1978) ape language experiments. The results show that languages that use combination of words (e.g. verb­object rule) can emerge by auto­ organization and cultural transmission. Neural networks are tested to see if evolved languages are based on symbol acquisition. The implications of this model for Deacon's (1997) hypothesis on the role of symbolic acquisition for the origin of language are discussed.
1. Symbol acquisition in the evolution of communication The synthetic approach of Artificial Life has recently been applied to studying the evolution of communication and language (Steels, 1997). Some models have been used for the simulation of the emergence of simple lexicons in populations of simulated organisms (e.g. Cangelosi & Parisi, 1998; MacLennan & Burghardt, 1994) or in small communities of robots (Steel & Vogt, 1997). In these studies organisms evolve shared lexicons for describing entities and relations of the environment. Other models have focused on the evolution of syntax (e.g. Kirby & Hurford, 1997). Simulated organisms evolve different syntactic languages starting from a given set of syntactic structures and constraints, and devices for syntax acquisition. The first type of model, that focus on lexicon emergence, do not make any explicit reference to the role of syntax in language ...
