This goes for dogs and other animals as well. All of these are examples how variation withing a species related to Darwin's theory of evolution.
C. punctuated equilibrium. Scientists believe in two evolutionary theories: gradualism and punctuated equilibrium. If punctuated equilibrium suggests species can rapidly evolve into a new species, gradualism suggests that these changes (selection and variation) happen more gradually.
