Two squirrel species evolved as a result of allopatric speciation. Some interbreeding still occurs between the apple-specialized flies and the hawthorne-specialized flies, so they are not yet separate species. summary pages are the perfect way to scaffold notes or review the concepts of speciation such as gene pool, mechanisms of isolation, genetic drift, natural selection and and causes of speciation.
