Microevolution and Macroevolution are two scales of evolutionary change that describe different processes and outcomes in the evolution of organisms.
Microevolution refers to small, gradual changes that occur within a population over a relatively short period. These changes typically involve alterations in allele frequencies due to natural selection, genetic drift, mutations, and gene flow. Microevolution leads to variations within a species but does not result in the formation of new species.
Macroevolution involves larger-scale evolutionary changes that occur over long periods, leading to the formation of new species, genera, families, or higher taxonomic groups. Macroevolutionary processes include the accumulation of microevolutionary changes over time and often involve speciation events, mass extinctions, and major evolutionary transitions.
