普赖斯方程从一开始就与社会进化理论纠缠在一起。它被用来推导出亲属选择理论的最一般版本，普赖斯本人提出了一个多水平方程，提供了社会进化理论的另一种表述，将选择划分为群体之间和群体内的组成部分。从这个意义上讲，普赖斯方程构成了亲属和群体选择的基础，因此在文献中经常相互竞争。背景分析和邻接法是分析群体选择的主要替代方法。我讨论了社会进化理论的这四种方法及其与普赖斯方程的联系，重点讨论了它们的相似性和共同的数学结构。尽管有不同的符号和建模传统，但所有四种方法最终都通过一组共同的数学组件联系在一起，以一种透明的方式揭示了它们潜在的统一性。普赖斯方程同样可以用来推导简化的、弱选择的社会进化建模方法。这些弱选择模型是进化生态学和行为生态学中构建模型的实用而有力的方法，它们可以澄清模型的因果结构，并且可以像回归方法一样容易地在四种社会进化方法之间进行转换。本文是主题期刊《价格方程式五十年》的一部分。
The Price equation has been entangled with social evolution theory from the start. It has been used to derive the most general versions of kin selection theory, and Price himself produced a multilevel equation that provides an alternative formulation of social evolution theory, dividing selection into components between and within groups. In this sense, the Price equation forms a basis for both kin and group selection, so often pitted against each other in the literature. Contextual analysis and the neighbour approach are prominent alternatives for analysing group selection. I discuss these four approaches to social evolution theory and their connections to the Price equation, focusing on their similarities and common mathematical structure. Despite different notations and modelling traditions, all four approaches are ultimately linked by a common set of mathematical components, revealing their underlying unity in a transparent way. The Price equation can similarly be used in the derivation of streamlined, weak selection social evolution modelling methods. These weak selection models are practical and powerful methods for constructing models in evolutionary and behavioural ecology; they can clarify the causal structure of models, and can be easily converted between the four social evolution approaches just like their regression counterparts. This article is part of the theme issue ‘Fifty years of the Price equation’.
