The evolution of cooperative hierarchies through natural selection processes

摘要: According to a bioeconomic model called skew selection, individuals form cooperative hierarchies when coping with high risk environments that include predators and cycles of scarce resources. This paper reports study used agent-based computer simulations experimentally test the predictions selection. Results experiment showed successful face-to-face transaction strategies varied environmental risks. Risks involving resource scarcity favored clustering stealing. hoarding. A combination risks sharing. Wealthy donors gained safety-in-numbers protect them from predators; at same time, marginal recipients resources starving. In summary, our findings show even though natural selection is not moral process, it can produce behavior.
