自然选择既通过性状对个体自身适应性的影响直接起作用，也通过性状对个体的遗传相关社会伙伴适应性的影响间接起作用。这些效应通常是根据汉密尔顿的规则rb-c> 0来构建的，它提供了社会进化理论的核心结果。然而，一些研究质疑汉密尔顿规则的普遍性，认为它需要限制性的假设。在这里，我们使用费舍尔的遗传学范式来证明汉密尔顿的规则的一般性，并澄清不同的研究之间的联系。我们发现，由于研究人员错误地识别模型参数与汉密尔顿规则中的B和c项，以及错误地识别基因型相似性或遗传相关系数r的系谱关系的措施，出现了混乱。更一般地说，我们强调有必要区分一般的亲属选择理论，形成社会进化的基础，和简化的亲属选择方法，用于解决具体问题。
Natural selection operates both directly, via the impact of a trait upon the individual's own fitness, and indirectly, via the impact of the trait upon the fitness of the individual's genetically related social partners. These effects are often framed in terms of Hamilton's rule, rb - c > 0, which provides the central result of social-evolution theory. However, a number of studies have questioned the generality of Hamilton's rule, suggesting that it requires restrictive assumptions. Here, we use Fisher's genetical paradigm to demonstrate the generality of Hamilton's rule and to clarify links between different studies. We show that confusion has arisen owing to researchers misidentifying model parameters with the b and c terms in Hamilton's rule, and misidentifying measures of genotypic similarity or genealogical relationship with the coefficient of genetic relatedness, r. More generally, we emphasize the need to distinguish between general kin-selection theory that forms the foundations of social evolution, and streamlined kin-selection methodology that is used to solve specific problems.
