Evolution is defined as a change in the genetic composition of a population over time, specifically from one generation to the next. This change is brought about by several mechanisms, including natural selection, genetic drift, mutation, and gene flow. A change in living conditions may influence evolutionary change, but it is not sufficient to define evolution. Similarly, changes in genetic composition that occur from one day to the next are not considered evolution because they do not involve a change in the gene pool of a population over time.
