Question

Quizplus · Accepted Answer

Once members of a species are geographically isolated, they may experience natural selection, genetic drift, and new mutations. Natural selection can cause certain traits to become more or less common in a population based on their usefulness in the environment. Genetic drift can result in random changes in allele frequencies due to chance events, such as genetic bottlenecks or founder effects. New mutations can introduce genetic variation that can be acted upon by natural selection and genetic drift. Therefore, all three factors can contribute to the divergence of populations over time.
