While microevolution is limited to small scale changes that occur within a population, macroevolution embodies the speciation and diversification of multiple species. Macroevolution generally takes more time than microevolution, since the evolutionary changes that occur are often drastic and can easily take thousands of years. Macroevolution generally affects multiple structures in an organism, instead of small genetic changes brought upon by microevolution.

Both forms of evolution are made possible by mutations, small genetic anomalies that bring about change within the genes of an organism.
