Answer
Greater species diversity could be observed in a planet experiencing intense tectonic activity. Movement of plates and continents or creation of mountains and the ocean floor causes geographic isolation. When this occurs, populations of the same species are separated, typically in small groups. Given enough time, these small groups would evolve and adapt to their new habitat, creating a more diverse community.
