The idea is that students can do this online and submit via Google Classroom. The water and distance between the two species keep them isolated from one another and make it impossible for them to breed. The process of forming new species from a pre-existing species is called anagenesis. This could also happen from the, larger population and establishes a group in an isolated area. Worksheets to go with the PowerPoints3. A physical barrier, such as a mountain range or a waterway, makes it impossible for them to breed with one another. Speciation is the process of formation of a new genetically independent group of organisms, called species, through the course of evolution. For example, members of a mainland population may become isolated on an island if they float over on a piece of debris. Why would groups of organisms in a population stop interbreeding when they still live in the same place?
