Detailed explanation-1: -Microevolution is defined as changes in the frequency of a gene in a population. These are subtle changes that can occur in very short periods of time, and may not be visible to a casual observer.

Detailed explanation-2: -Evolution is a process that results in changes in the genetic material of a population over time. Evolution reflects the adaptations of organisms to their changing environments and can result in altered genes, novel traits, and new species.

Detailed explanation-3: -Small-scale evolution or microevolution concerns evolution at the intra-specific level or between closely related species. At the intra-specific level, it allows the analysis of the evolutionary forces at work: mutation, genetic drift, migration and selection.

Detailed explanation-4: -There are a few basic ways in which microevolutionary change happens. Mutation, migration, genetic drift, and natural selection are all processes that can directly affect gene frequencies in a population.

Detailed explanation-5: -Summary. Microevolution is the process by which organisms change in small ways over time. Macroevolution refers to larger evolutionary changes that result in new species.
