合作的演变取决于两个关键的总体因素:相关性,它描述了接受者与参与者共享基因的程度;和质量,它描述了接受者将基因传递到未来的基本能力。虽然大多数研究都集中在相关性上,人们对理解质量如何调节合作的演变越来越感兴趣。然而,质量传承对合作演变的影响在很大程度上仍未被探索,特别是在空间结构的人群中。这里,我们开发了一个数学模型来理解质量的继承,以社会地位的形式,影响在粘性人口环境中社会群体中帮助和伤害的演变。我们发现:(1)状态反转传递,父母和后代的地位是负相关的,强烈抑制合作的发展,地位低的人在合作方面的投资较少,地位高的人更容易受到伤害;(2)地位高的传播促进后代的哲学,与更多的合作针对更分散的社会阶层;(3)生育不平等和代际地位继承减少了群体内的冲突。总的来说,我们的研究强调了考虑不同表型遗传机制的重要性,包括社会支持,以及它们在塑造动物社会中的潜在相互作用。
The evolution of cooperation depends on two crucial overarching factors: relatedness, which describes the extent to which the recipient shares genes in common with the actor; and quality, which describes the recipient\'s basic capacity to transmit genes into the future. While most research has focused on relatedness, there is a growing interest in understanding how quality modulates the evolution of cooperation. However, the impact of inheritance of quality on the evolution of cooperation remains largely unexplored, especially in spatially structured populations. Here, we develop a mathematical model to understand how inheritance of quality, in the form of social status, influences the evolution of helping and harming within social groups in a viscous-population setting. We find that: (1) status-reversal transmission, whereby parental and offspring status are negatively correlated, strongly inhibits the evolution of cooperation, with low-status individuals investing less in cooperation and high-status individuals being more prone to harm; (2) transmission of high status promotes offspring philopatry, with more cooperation being directed towards the higher-dispersal social class; and (3) fertility inequality and inter-generational status inheritance reduce within-group conflict. Overall, our study highlights the importance of considering different mechanisms of phenotypic inheritance, including social support, and their potential interactions in shaping animal societies.
