....a rapid process. The underlying mechanism, called implicit parallelism by Holland (Holland 1975; Goldberg 1989) is used in computer optimisation for its rapidity. The fact that genes are selected in parallel is not considered by those evolutionary accounts which insist on evolutionary speed limits (Worden 1998). Thanks to the rapidity of evolutionary changes, species stay most of the time in equilibrium. They occupy different adaptive local optima and thus differ qualitatively. Following Monod (1970) we consider that language, at least in some primitive form, contributed to make such a qualitative ....

....base (KB) in our case implemented as a system of classes of objects and their instantiations. To facilitate effective communication, the agent s KB has to include information about the possible states of knowledge, abilities and preferences of the other agent(s) present in the environment [10, 19, 47]. For the purpose of decision theoretic calculations we use the formalism of the Recursive Modeling Method (RMM) 16, 17] The advantage of RMM, when used for expected utility calculation, is that is able to succinctly represent the content of the agent s KB, including its preferences, abilities, ....

....and about other agents, their beliefs about others beliefs, and so on. The need for considering the nestedness of the agents beliefs for communication has been widely recognized in the linguistics and AI literatures before [2, 4, 6, 8, 18, 19, 31, 35, 38, 39] while research in cognitive science [11, 47] yielded evidence of nested mental models used by humans for purpose of communication. Clearly, without a model of the other agents mental states it would be impossible to properly assess the impact of a communicative act. We should note that the RMM representation is not intended as a general ....

....than a pure cognitivist) approach to the problem of grounding communication as we investigate the influence of social and behavioural aspects onto the development of communication. Our approach differs from previous studies on the influence of sociality onto the development of communication (e.g. [18, 44, 45, 56]) as we give a complete spatial and temporal description of our agents behaviour. This allowed us to point out the influence on the success of the learning of environmental factors (see [5] such as the teaching of objects featural description and relative dispersion in the environment in ....

However, the question of the origin of the LAD, as opposed to its subsequent evolution and maintenance, is not addressed further in this paper. 7 the basis of minimal environmental stimulus, providing that the environment, and consequent selection pressure, remains constant over enough ....

....once animals can learn to communicate by observing others, the achievement of syntactic communication is an extension that is comparatively less difficult. Recent work involving computational simulations of the origins of syntax supports this view (Batali, 1997; Hutchins and Hazelhurst, 1997; Worden, 1997; Kirby, 1998) In either case, it is a mistake to take the existence of simple innate communication systems in other species to imply that the problem of the lexicon in language evolution is solved. To do so is to ignore the important distinction between innate and learned communication. The ....
