.... the 8 Bounty mutineers arrived, and the 6 consequences linguistic and otherwise were dramatic (Romaine, 1988) More importantly, though populations might typically run to the thousands, networks of strong and regular linguistic interaction are probably limited to group sizes of around 100 150 (Dunbar, 1993; Milroy, 1992; Nettle, 1999) Slide 6 shows runs where initially there is a single g 1 speaker in a population of 100 but there is a greater proportion of unambiguous triggers for g 1 than g 2 . In the top graph a g 1 unambiguous trigger is twice as likely as a g 2 one. In the bottom ....

.... Recent studies on the development of communication have addressed the problem essentially from an evolutionary perspective, 1) either through theoretical models based on biological studies of brain evolution (e.g. 16, 46] or on sociological studies of primates and human societies (e.g. [2, 18]) 2) or through computer simulations (e.g. 28, 34, 45, 43, 51] For these studies, the symbol grounding problem 2 [22] is solved, once the necessary cognitive abilities have evolved. However, few of these studies consider the influence of behavioural and social factors on the development of ....

....(e.g. 28, 34, 45, 43, 51] For these studies, the symbol grounding problem 2 [22] is solved, once the necessary cognitive abilities have evolved. However, few of these studies consider the influence of behavioural and social factors on the development of communication, exceptions are [18, 45]. A common trend among the above mentioned simulation studies is to give a very simplified physical description of the communicative agents and their environment. The communicative agents are described only in terms of their cognitive (by opposition to behavioural) abilities that enable production ....

Nevertheless, there is a limit to genetic assimilation in the face of ongoing linguistic change: in simulation runs with LAgts initialized with all default parameters, populations evolve away from such fully assimilated LADs (Briscoe, 1998a,b) when linguistic variation is maintained. 7 ....

....factual information to another. It would seem that there is usually little immediate benefit to a speaker in giving declarative information to another. Classic references on the evolution of altruism, though with no reference to language, are Trivers (1971) and Hamilton (1964) Group size Robin Dunbar (1993, 1996) has argued that the typical size of human clans and networks of intimates hovers significantly around the number 150. Briefly, language evolved as a response to the necessity of servicing the enormous number of relationships with other individuals that a group of 150 presents. Bonding by ....
