The Price equation (also known as Price's equation or Price's theorem) is a covariance equation which is a mathematical description of evolution and natural selection. The Price equation was derived by George R. Price, working in London to re-derive W.D. Hamilton's work on kin selection. The Price equation also has applications in economics.
Price's equation is a theorem; it is a statement of mathematical fact between certain variables, and its value lies in the insight gained by assigning certain values encountered in evolutionary genetics to the variables. It provides us a way to understand the effects that gene transmission and natural selection have on the proportion of genes within each new generation of a population.

Famous quotes containing the words price and/or equation:
“Thou blind man’s mark, thou fool’s self-chosen snare,
Fond Fancy’s scum and dregs of scattered thought,
Band of all evils, cradle of causeless care,
Thou web of will whose end is never wrought;
Desire! desire, I have too dearly bought
With price of mangled mind thy worthless ware;”
—Sir Philip Sidney (1554–1586)
“A nation fights well in proportion to the amount of men and materials it has. And the other equation is that the individual soldier in that army is a more effective soldier the poorer his standard of living has been in the past.”
—Norman Mailer (b. 1923)
