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. A physical barrier, such as a mountain range or a waterway, makes it impossible for them to breed with one another. Speciation by polyploidy is common in plants but rare in animals. There are multiple ways to define the concept of "species." The choice of definition is dependent on the particularities of the species concerned. It is the process by which an ancestral species splits into two or more new species. It was aligned exactly with what I needed.
