Five mechanisms that can lead to evolution
Weba simple general rule can be shown without any difficulty. Direct reciprocity can lead to the evolution of cooperation only if the probability, w, of another encounter between the same two individuals exceeds the cost-to-benefit ratio of the altruistic act: w > c/b (2) Indirect Reciprocity Direct reciprocity is a powerful mechanism WebCoexistence mechanisms can be classified into two groups on the basis of whether they reduce inherent differences in species performance (equalizing effects) or buffer against extinction by providing advantages to rare species (stabilizing effects). ... Theoretical and empirical evidence suggests that rapid evolution can increase equalizing and ...
