亲缘选择、直接互惠和基于需求的转移等社会进化理论在解释现实世界中的合作时的相对重要性是众多争论的源头。先前对人类社区合作的实地研究揭示了在不同情境下，这些理论对人类社会性的解释程度存在差异。我们对中国西南部128082对摩梭农户进行了多元社会网络分析，以预测费力的合作——在另一个家庭的农场劳作。通过信息论模型选择，我们测试了谱系亲缘关系、姻亲关系（包括配偶关系）、互惠、相对需求、财富、家庭规模、空间邻近性以及在一个经济博弈中的送礼行为所起的作用。最适配的模型包含了所有因素，以及亲缘关系与（i）互惠、（ii）需求、（iii）自家孩子在另一个家庭中的情况以及（iv）邻近性之间的相互作用。我们的研究结果表明了一种现实世界中的合作形式是如何由亲属关系驱动的。家庭往往会帮助有需要的亲属（但不帮助有需要的非亲属），并且会前往更远的地方帮助空间上距离较远的亲属。家庭更有可能与远亲及非亲属建立互惠关系，但近亲之间的合作不考虑互惠。这些由亲属驱动的合作模式表明了广义适合度在理解人类社会行为方面的重要性。
The relative importance of social evolution theories such as kin selection, direct reciprocity and need-based transfers in explaining real-world cooperation is the source of much debate. Previous field studies of cooperation in human communities have revealed variability in the extent to which each of these theories explains human sociality in different contexts. We conducted multivariate social network analyses predicting costly cooperation—labouring on another household's farm—in 128 082 dyads of Mosuo farming households in southwest China. Through information-theoretic model selection, we tested the roles played by genealogical relatedness, affinal relationships (including reproductive partners), reciprocity, relative need, wealth, household size, spatial proximity and gift-giving in an economic game. The best-fitting model included all factors, along with interactions between relatedness and (i) reciprocity, (ii) need, (iii) the presence of own children in another household and (iv) proximity. Our results show how a real-world form of cooperation was driven by kinship. Households tended to help kin in need (but not needy non-kin) and travel further to help spatially distant relatives. Households were more likely to establish reciprocal relationships with distant relatives and non-kin but closer kin cooperated regardless of reciprocity. These patterns of kin-driven cooperation show the importance of inclusive fitness in understanding human social behaviour.
