Modes of Speciation Traditional classification is by degree of geographic separation. How does reproductive isolation develop in a polytypic species? RIMS = Reproductive Isolating Mechanisms arise fortuitously, epistatically SRMS = Species Recognition Mechanisms arise by natural selection Modern classification emphasizes population genetic processes involved. What genetic changes occur during speciation?
