What is the correct definition of macroevolution?
A. It is evolutionary change on a large scale often following major global changes and mass extinction
B. It is evolutionary change due to dominant modification that enriches a gene pool over very short periods of time
C. It is evolution change due to recessive modification that enriches a gene pool over very short periods of time
Macroevolution is evolution on a scale of separated gene pools. Macroevolutionary studies focus on change that occurs at or above the level of species, in contrast with microevolution.
