What is the type of evolution characterized by small changes in populations over long periods of time?

Small changes in populations over long periods of time is a type of evolution called microevolution. Microevolution refers to the gradual changes that occur within a species as a result of processes like mutation, natural selection, gene flow, and genetic drift. These changes can lead to variations in traits among individuals in a population, such as coloration, size, and reproductive capabilities. Over time, if these changes accumulate, they can contribute to the formation of new species.
