f its transitions and the ease with which the survival game may be embedded within it, we base our model on the haploid population-genetic model of Moran (1958).The standard version of the Moran model pairs single births and deaths such that the population size remains constant.

In the language of evolutionary graph the

The traditional approach to evolutionary game theory is based on the replicator equation (Taylor & .Jonker 1978, Hofbauer et al 1979, Zeeman 1980, Hofbauer & Sigmund 1988,1998, 2003, Cressman 2003), which examines deterministic dynamics in infinitely large, well-mixed

In each time step a randomly chosen individual is replaced by a copy of an individual chosen with probability proportional to its payoff.

es over it (Nowak & Sigmund 2004). The classical approach to evolutionary game dynamics is based on the replicator equation (Taylor Sc Jonker 1978, Hofbauer et at 1979, Zeeman 1980, Hofbauer & Sigmund 1988, 1998). The population is well-mixed and infinitely large. Any two individuals are equally likely t
