Language evolution, social phenomena

Results on language coevolution in groups of agents were presented in this paper. The dynamics of language development was shown and discussed in a single group and between two groups of agents. In the first case, three kinds of societies were simulated, i.e.: cooperative, competitive and individual. In the second case, relations were defined for mutualism, competition and predation. Both cases enabled observations on variety of phenomena like adaptation, arms race or chaos.
