The Price Equation

The Price Equation is a mathematical way to understand how groups or traits change over time through processes like evolution. It breaks down the change into two parts: one from differences within groups (like variation in individual traits) and another from differences between groups (like different group success rates). Essentially, it helps explain how certain traits become more common because they offer advantages, and how all these factors influence the overall change in a population’s characteristics. It’s a useful tool for studying how and why populations evolve over generations.
