Microevolution, broadly defined, is the inevitable small-scale changes in allele frequencies in a population within the same species. Under this broad definition, this change in overall allele frequencies occurs with every birth or death of a member of the species.
Microevolution, narrowly defined, is the theory that natural selection can, over time, increase the overall reproductive fitness of a species. [1]
