This means evolution at the level of a species, or higher. For example, the evolution of land animals into whales would be macroevolution. A species of moth turning black is microevolution (change within a species). A new species arising ( speciation) is therefore macroevolution. Many Creationists say that their argument is with macroevolution, and not microevolution. Most scientists consider macroevolution to just be microevolution which has gone on for a long time. However, some scientists argue that the distinction between macro- and micro- is useful.
