Lifetime genetic monogamy, by increasing sibling relatedness, has been proposed as an important causal factor in the evolution of altruism. Monogamy, however, could influence the subsequent evolution of cooperation in other ways. We present several alternative, non-mutually exclusive, evolutionary processes that could explain the correlated evolution of monogamy and cooperation. Our analysis of these possibilities reveals that many ecological or social factors can affect all three variables of Hamilton's Rule simultaneously, thus calling for a more holistic, systems-level approach to studying the evolution of social traits. This perspective reveals novel dimensions to coevolutionary relationships and provides solutions for assigning causality in complex cases of correlated social trait evolution, such as the sequential evolution of monogamy and cooperation.
终生遗传一夫一妻制通过增加兄弟姐妹之间的亲缘关系，被提议作为利他主义进化的一个重要因果因素。然而，一夫一妻制可能会以其他方式影响合作的后续进化。我们提出了几种可供选择的、非互斥的进化过程，可以解释一夫一妻制和合作的相关进化。我们对这些可能性的分析表明，许多生态或社会因素可以同时影响汉密尔顿规则的三个变量，因此需要采用更全面的、系统层面的方法来研究社会特征的进化。这种观点揭示了协同进化关系的新维度，并为在相关社会特征进化的复杂情况下（例如一夫一妻制和合作的顺序进化）确定因果关系提供了解决方案。
