Coevolution of cooperation, causal cognition and mindreading

open access: yesCommunicative & Integrative Biology, 2010
The evolution of cooperation between unrelated individuals has long been a puzzle in evolutionary biology. Formal models show that reciprocal altruism is approximately as stable as kin-based altruism when cooperators can assort.
