# Price Equation

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 equation and/or price:

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)

I have asked a lot of my emotions—one hundred and twenty stories. The price was high, right up with Kipling, because there was one little drop of something, not blood, not a tear, not my seed, but me more intimately than these, in every story, it was the extra I had. Now it has gone and I am just like you now.
F. Scott Fitzgerald (1896–1940)
