Dear All,

I am fooling about with a very simple evolutionary model. Agents have a "gene" (in the sense that it is inherited with small mutation and stays fixed for the life time) which determines what fraction of available "food" they take from a patch (from 0 - too altruistic to survive - to 1 - take everything you can get). The added wrinkle is that if an agent takes all food off a patch then it is "denuded" and can't regrow. You might think that "stupidly selfish" agents would die out but, unfortunately, they keep their reproductive advantage relative to more "moderate" agents until _everyone_ dies!

Am I unintentionally making stupid assumptions in evolutionary terms to get this outcome? What, in biological evolution, stops the quest for individual reproductive success from destroying the environment? Can this model only work if we assume that
there is no total denudation? (Some other species of grass or food will always come along or it is really not possible to "forage the environment to death?")

All thoughts welcome,

Edmund
