Abstract This paper reports on an internship at the department of theoretical biology at Utrecht University between October 1998 and February 1999. Aim of the project was to implement and study the compu­ tational model of language evolution reported by Hashimoto & Ikegami (1996) and to reproduce their results. The project was undertaken as a preparation for more original research for a master's thesis, and among other things to improve programming skills and to get more familiar with language evolution and modeling methodology. This report consists of six sections, discussing the origin of language de­ bate, the Hashimoto ­ Ikegami model, the developed implementation, the main results with some hints on subsequent work, conclusions and a short self­evaluation.
1 Introduction 1.1 the origins of language The transition from short, finite communication systems found in many animal species, to the open end­ ed language system of humans, is considered to be one of the major transitions in evolution (Szathm’ ary & Maynard­Smith, 1995). There is large consensus that the qualitative difference is in the phrase struc­ ture of human language: grammatical rules provide constraints on the form of expressions, but at the same time allow for a systematic production and interpretation of an astronomical number of different messages. The characteristics of the transition from animal to human communication, however, remain an in­ triguing, unsolved problem. In recent years the scientific debate on the origins and the nature of the human language ...
