Reciprocal altruism
mechanistic work on the response threshold concept, I think this part of the book reviews important work in social insect biology and in behavioral genetics in general. Page finishes his book by focusing on the reproductive ground plan work he has conducted in recent years with Gro Amdam and others. This is the study of how core genetic modules (primarily relating to reproductive physiology) ha...
متن کاملKin altruism, reciprocal altruism and social discounting
According to evolutionary psychologists, human pro-social behaviour is regulated by evolutionarily developed psychological mechanisms whose role is to solve adaptive problems. The same reasoning can be applied to social discounting, i.e. subjective devaluation of a reward which must be shared with one or more people. Based on reciprocal altruism and inclusive fitness theories, hypotheses were f...
متن کاملModelling Reciprocal Altruism
Biologists rely extensively on the iterated Prisoner's Dilemma game to model reciprocal altruism. After examining the informal conditions necessary for reciprocal altruism, I argue that formal games besides the standard iterated Prisoner's Dilemma meet these conditions. One alternate representation, the modified^Prisoner's Dilemma game, removes a standard but unnecessary condition; the other ga...
متن کاملHeterogeneity stabilizes reciprocal altruism interactions.
In considering the phenomena of reciprocal altruism few would dispute that there are differences in individual quality-in particular, that for some individuals, at least on occasion, the cost of doing favors will exceed the potential of future benefits. That is, at any given time, a typical population is heterogeneous with respect to the affordability of reciprocal altruism. However, methodolog...
متن کاملThe Evolution of Reciprocal Altruism
A model is presented to account for the natural selection of what is termed reciprocally altruistic behavior. The model shows how selection can operate -against the cheater (non-reciprocator) in the system. Three instances of altruistic behavior are discussed, the evolution of which the model can explain: (1) behavior involved in cleaning symbioses; (2) warning cries in birds: and (3) human rec...
