Evolutionarily stable communication between kin:a general model

Evolutionarily Stable Communication and Pragmatics

In the past 20 or so years there has been much research interest in the evolution of cooperation in humans (Axelrod, 1995; Boyd & Richerson, 1992; Fehr & Fischbacher, 2003; Milinski et al., 2002; West et al., 2006). The foundational problem addressed by this work is how cooperation can remain evolutionarily stable when individuals have incentives to freeride; that is, to take but not contribute...

Is altruism evolutionarily stable

We develop an evolutionary approach to explain altruistic preferences. Given their preferences, individuals interact rationally with each other. By comparing the success of players with different preferences, we investigate whether evolution favors altruistic or selfish attitudes. The outcome depends on whether the individuals' interactions are strategic complements or substitutes. Altruism and...

Evolutionarily stable dispersal strategies.

Using the idea that life-history parameters are subject to natural selection and should approach values that are stable optima, with the population immune to invasion by mutant individuals, we derive an analytic expression for the evolutionarily stable dispersal rate in a stochastic island model with random site extinction. The results provide interesting contrasts between three different optim...

10 Evolutionarily Stable Strategies

In 1973 the biologist John Maynard Smith and the mathematician G. R. Price wrote an article in Nature showing how game theory applies to the behavior of animals (Maynard Smith and Price 1973). Maynard Smith went on to write a book on the subject (Maynard Smith 1982), which has become a classic. The idea of applying game theory to animals, and not just the higher primates, but fish, dung beetles...
