How did Pangaea affect evolution?

Evolution was not the cause of the breakup of Pangaea. Pangaea broke up by a process called rifting. Upwelling in Earth's mantle started to pull the conteinent apart. As the curst thinned, it led to the formation of volcanoes, which generated new crust, helping to push the continent apart. Evolution is the process by which groups of organisms change over time. While the breakup of Pangaea undoubtedly affected the course of evolution, evolution had nothing to do with causing the breakup.
