从可观察行为推导进化收益

Derivation of evolutionary payoffs from observable behavior

Alexander Feigel, Avraham Englander, Assaf Engel

摘要:

解释动物的行为,特别是合作或自私,是对进化理论的挑战。竞争的策略应该遵循相应的达尔文收益的可用行为选项。然而,收益和决策过程很难观察和量化。在这里,我们提出了一个通用的方法,从可观察的统计相互作用的进化收益的推导。该方法被应用到男性碗和doily蜘蛛的战斗,捕食者检查棘鱼和狮子的领土防御,展示动物行为作为一种新型的博弈理论均衡。动物玩的游戏可以明确地从它们可观察的行为中推导出来,然而,由于我们无法观察到所有的信息交换机制(通信),重建可能受到根本性的限制。

英文摘要:

Interpretation of animal behavior, especially as cooperative or selfish, is a challenge for evolutionary theory. Strategy of a competition should follow from corresponding Darwinian payoffs for the available behavioral options. The payoffs and decision making processes, however, are difficult to observe and quantify. Here we present a general method for the derivation of evolutionary payoffs from observable statistics of interactions. The method is applied to combat of male bowl and doily spiders, to predator inspection by sticklebacks and to territorial defense by lions, demonstrating animal behavior as a new type of game theoretical equilibrium. Games animals play may be derived unequivocally from their observable behavior, the reconstruction, however, can be subjected to fundamental limitations due to our inability to observe all information exchange mechanisms (communication).
