Question

Quizplus · Accepted Answer

Microevolution refers to small-scale evolutionary changes that occur within a population, such as changes in the frequency of alleles or traits from one generation to the next. The formation of new species (speciation) and the extinction of species are examples of macroevolution, while the origin of flight within a taxon would likely involve multiple evolutionary changes and could also be categorized as macroevolution.
