A simple and general explanation for the evolution of altruism.

Proceedings. Biological sciences - 7 Jan 2009

Fletcher Jeffrey A, Doebeli Michael

Abstract excerpt

We present a simple framework that highlights the most fundamental requirement for the evolution of altruism: assortment between individuals carrying the cooperative genotype and the helping behaviours of others with which these individuals interact. We partition the fitness effects on individuals into those due to self and those due to the 'interaction environment', and show that it is the latter that is most...
