Macroevolution is a term (coined by
Theodosius Dobzhansky) used by evolutionary biologists to to refer to major, long term features of
evolution, typically above the
species level. Macroevolution is concerned with patterns of major morphological change, and it is typically pursued by those studying
paleontology or the
evolution of
development.
The study of macroevolution is linked to microevolution by the study of speciation, the process of one species becoming two species with independent evolutionary fates.
