1.1 Introduction Evolutionary modelling is moving into the challenging field of the evo­ lution of syntactic systems. In this chapter 1 , five recent models will be compared. The following abbreviations will be used in referring to them. Batali (1998) JB1 Batali (this volume) JB2 Hurford (in press) JH Kirby (in press) SK1 Kirby (this volume) SK2 Other related work will be mentioned where relevant 2 3 . The goals of the comparison will be to highlight shared and different assumptions and consequent shared and different outcomes. The models of the evolution of syntax that have been constructed so far fall short of the kind of syntactic complexity found in real languages. 1 This general kind of work was significantly stimulated by a workshop in compu­ tational evolutionary syntax sponsored by the Collegium Budapest Institute for Advanced Study in 1997. The particular work of this paper was substantially helped by a UK ESRC research grant, No. R000 237551. I thank Simon Kirby, John Batali, Ted Briscoe and Mike Oliphant for helpful comments, but I take sole responsibility for what is said here. 2 The discussion of JB2 here is based largely based on a slightly earlier version than that published in this volume. Nothing significant turns on this. 3 Steels (1998) outlines a model very similar in spirit to those compared here, but gives no details of any language­like system that is its outcome. For this reason, and for lack of space, it is discussed in less detail here. 1 2 1. Expression/Induction models of language evolution In this work, idealization and simplification are immediately obvious. So far, the emergent language systems are, by the standards of extant languages, very simple. The models surveyed here all claim to present examples of the evolution from situations with no ...
