社会组织与动物类群的寿命相关。这种相关性可以通过社会进化对长寿的选择来解释。反向因果关系也是可以想象的，但尚未得到充分考虑。我们构建了一个简单的、空间结构的无性繁殖个体种群模型，以研究时间生活史结构对合作进化的影响。在基本的囚徒困境范式中，个人对所有邻居采用固定的合作或背叛策略。个体在不迁移的情况下异步衰老并经历不同的生命史阶段。一个人的死亡引发了一个近邻的繁殖事件。根据所有本地交互的累积收益，概率性地选择特定的邻居。通过改变生殖前、生殖和生殖后生命史阶段的持续时间，长期模拟可以系统地评估这些特定生命史阶段持续时间的影响。我们的结果揭示了三个基本生命史阶段的影响与缺陷的益处之间复杂的相互作用。总体而言，较长的生殖后阶段促进了合作的进化，而较长的生殖前阶段则具有负面影响。一般来说，生命总长度也增加了合作进化的概率。因此，我们的具体模型表明，生活史转变的时间和生活史阶段的总持续时间可能会影响合作行为的演变。我们得出的结论是，根据经验观察到的预期寿命与社会性之间的关联的因果关系可能比之前意识到的更为复杂。
Social organization correlates with longevity across animal taxa. This correlation has been explained by selection for longevity by social evolution. The reverse causality is also conceivable but has not been sufficiently considered. We constructed a simple, spatially structured population model of asexually reproducing individuals to study the effect of temporal life history structuring on the evolution of cooperation. Individuals employed fixed strategies of cooperation or defection towards all neighbours in a basic Prisoner’s Dilemma paradigm. Individuals aged and transitioned through different life history stages asynchronously without migration. An individual’s death triggered a reproductive event by one immediate neighbour. The specific neighbour was chosen probabilistically according to the cumulative payoff from all local interactions. Varying the duration of pre-reproductive, reproductive, and post-reproductive life history stages, long-term simulations allowed a systematic evaluation of the influence of the duration of these specific life history stages. Our results revealed complex interactions among the effects of the three basic life history stages and the benefit to defect. Overall, a long post-reproductive stage promoted the evolution of cooperation, while a prolonged pre-reproductive stage has a negative effect. In general, the total length of life also increased the probability of the evolution of cooperation. Thus, our specific model suggests that the timing of life history transitions and total duration of life history stages may affect the evolution of cooperative behaviour. We conclude that the causation of the empirically observed association of life expectancy and sociality may be more complex than previously realized.
