EvolveIT allows you to manipulate various parameters of finches of the Galapagos Islands, such as variability, heritability, and beak size, and parameters of the environment, such as precipitation and island size. You can then observe the effect of these parameters on the evolution of bird beak morphology in the hypothetical bird populations.
