How did a single continent affect evolution?

The continents of the earth are constantly drifting, sometimes joining up against other land masses and forming supercontinents, and sometimes breaking up. Sometime before 250 million years ago, a single continent, now known as Pangea, incorporated all the major land masses of the earth. Evolution results as living things respond to environmental changes, and one of the aspects of the environment was the super-continent of Pangea. Successful life forms could migrate throughout the entire land area of the world, dominating the less successful and sometimes driving them to extinction. When Pangea began to break up, each separate land mass held species that had evolved on Pangea but now began to evolve in isolation, eventually creating new classes of life forms distinct from those on the other land mass.
