Price equation.31 It is the fundamental relation expressing how changes in any population average are the result of the combined effect of a variation in frequencies of types (selection or sorting; first term) and changes in the quantities themselves over time (transmission or endogenous growth; second term).

During the 1920s, following this fundamental insight of 19th- and early 20th-century physicists, the American mathematician and statistician Alfred Lotka concluded that those organisms that best capture the available energy hold the evolutionary advantage.21
