  Replicator dynamics originated within evolutionary biology. Subsequently, game theorists such as Larry Samuelson (1997) have argued that it illuminates social interaction among humans. Within philosophy, Brian Skyrms (1996, 1998) argues that replicator dynamics shows how conventions of property and linguistic meaning could evolve without any need for Lewisian “salience.” He places particular emphasis upon signaling games, that is, games in which a sender wishes to communicate a message to a receiver, a message determining which action from among a fixed repertoire the receiver will perform. (See  section 7.1   for more detail on signaling games.) For certain signaling games, replicator dynamics almost always converges to an evolutionarily stable signaling convention. Which convention emerges depends solely upon chance facts about players’ initial propensities to adopt various strategies (i.e., the basin of attraction from which the system happens to begin). As Skyrms puts it, “[w]hich signaling system is selected is a matter of chance, not of salience” (1996, p. 93).
