Microevolution refers to the small-scale genetic changes that occur within a population over successive generations. Unlike macroevolution, which involves large-scale changes leading to the emergence of new species, microevolution focuses on variations that can be observed directly within populations. Key Mechanisms of Microevolution Microevolution is driven by several fundamental mechanisms, including: - Mutation: Random changes in DNA sequences that introduce new genetic variations. - Gene flow: The transfer of alleles from one population to another, often through migration. - Genetic drift: Random fluctuations in allele frequencies, especially significant in small populations. - Natural selection: Differential survival and reproduction based on genetic traits, leading to advantageous traits becoming more common. Examples of Microevolution in Nature - Antibiotic resistance in bacteria - Changes in coloration of peppered moths during industrial revolution - Variations in beak sizes among finch populations - The development of pesticide resistance in insect populations --- The Role and Importance of the Microevolution Gizmo The microevolution gizmo is an interactive simulation tool designed to demonstrate how genetic variations and environmental factors influence populations over time.
