Special Speciation - UNI ScholarWorks
... Speciation occurs when separate populations become so genetically different that they can no longer mate successfully with each other. This can occur in different ways for different species, but most commonly geographic isolation (e.g., by mountains, oceans, or rivers) is an important part of the pr ...
