Allopatric speciation and sympatric speciation are the two major mechanisms by which new species form. Prezygotic and postzygotic barriers not only keep species distinct, but also play a role in the formation of new species, as we'll see next. Sign in The Grand Canyon was gradually carved out by the Colorado River over millions of years. Biologists often divide the ways that speciation can occur into two broad categories: Let's take a closer look at these forms of speciation and how they work. Both sexual selection and ecologi-cal causes of natural selection may result in speciation. Macroevolution: change above species level Use the biological species concept to define species. Worksheets to go with the PowerPoints3. Students will learn about the processes of allopatric and sympatric speciation before examining causes of extinction.
