In the theory of evolution and natural selection, the Price equation (also known as Price's equation or Price's theorem) describes how a trait or allele changes in frequency over time. The equation uses a covariance between a trait and fitness, to give a mathematical description of evolution and natural selection.
9 mar 2020 · Abstract. Price's equation provides a very simple—and very general—encapsulation of evolutionary change. It forms the mathematical foundations of several topics in evolutionary biology, and has also been applied outwith evolutionary biology to a wide range of other scientific disciplines.
9 mar 2020 · The Price equation is a statistical summary of evolutionary change, and it is widely acknowledged that statistical relations do not necessarily imply or directly map onto causal relations. So, caution is required when making claims about causality based solely on the Price equation.

9 mar 2020 · 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.
The Price equation is a complete description of the evolutionary process. With it, we partition the change in the mean of a trait from one generation to the next into two quantities: (1) the effect of transmission and (2) the effect of selection.
11 mar 2008 · The Price equation is a simple mathematical statement about change. In its usual formulation, it describes how the average value of any character — body weight, antler size, proclivity to altruism — changes in a biological population from one generation to the next.
