Microevolution and its complement macroevolution are terms used by creationists to divide examples of biological evolution into distinct categories. Microevolution covers small, distinct changes within a species (as in animal breeding) typically attributable to a single genetic change, while macroevolution refers to a change much larger in scope, such as the proposed evolution of primates into men, or from simple single-celled organisms into complex multi-celled organisms.

Biologists have long recognized a distinction between relatively minor changes within a species, which they call "microevolution," and the much larger changes necessary to produce significantly new features, which they call "macroevolution." Microevolution covers small, distinct changes within a species (as in animal breeding) typically attributable to a single genetic change, while macroevolution refers to a change much larger in scope, such as the proposed evolution of primates into men, or from simple single-celled organisms into complex multi-celled organisms.
