What happens to speciation after a mass extinction? Over the course of many generations, natural selection will act on these species, allowing them to take better advantage of available resources. As lineages invade different niches and become isolated from one another, they split, regenerating some of the diversity that was wiped out by the mass extinction.
Is there a connection between speciation and mass extinctions? Many of the traits associated with elevated rates of speciation, including niche specialization and having small and isolated populations, are similarly linked with an elevated risk of extinction. This suggests that rapidly speciating lineages may also be more extinction prone.
