The Price equation is recognized as a general statistical description of evolutionary change with the potential to represent diverse processes. Here we present a new structurally symmetric equation for change that allows for arbitrary causal connectivity between ancestors and descendants, accounts for previously unaddressed processes (such as migration), and yields the Price equation as a special case.
普赖斯方程被认为是对进化变化的一种通用统计描述，有潜力代表各种不同的过程。在此，我们提出了一个新的关于变化的结构对称方程，该方程允许祖先与后代之间存在任意因果联系，考虑了以前未涉及的过程（如迁移），并将普赖斯方程作为一个特例推导得出。
