Microevolution is simply a change in gene frequency within a population. Evolution at this scale can be observed over short periods of time — for example, between one generation and the next, the frequency of a gene for pesticide resistance in a population of crop pests increases.

There is one particular aspect of evolution that needs to be given specific attention: the somewhat artificial distinction between what is called 'microevolution' and 'macroevolution', two terms often used by creationists in their attempts to critique evolution and evolutionary theory. ... Macroevolution, in contrast,

Microevolution is distinct from macroevolution. ... Microevolution and macroevolution are different things, but they involve mostly the same processes. Microevolution is defined as the change of allele frequencies (that is, genetic variation due to processes such as selection, mutation, genetic drift, or even migration)
