Quizplus · Accepted Answer

Macroevolution refers to evolutionary changes that occur at or above the level of species, encompassing the grand scale of evolutionary transformations, such as the emergence of new species, genera, families, and higher taxonomic groups over geological time. It contrasts with microevolution, which involves smaller evolutionary changes (typically described as changes in allele frequencies) within a species or population over a shorter period.
