Microevolution

Microevolution is the small-scale evolutionary changes that occur over a short period of time in a population of organisms. These changes can include changes in allele frequencies or changes in the population's gene pool. Microevolution is an important mechanism of evolutionary change and is essential for the long-term evolution of species in response to the environment. Microevolution is the basis of natural selection and other evolutionary processes, providing the variation on which they act. Microevolution is also important for understanding how species and genetic diseases arise, and how resistance to diseases develops. It has implications for conservation, population management and medicine, and is a key for understanding the interplay between genetic and environmental change.
