Mass extinctions have occurred five times in earth's history. the permian and cretaceous extinctions removed a large percentage of organisms from the planet. how did these extinctions contribute to the patterns of biodiversity we see today? a. species that remained after the extinction were able to radiate, new adaptations arose, and these adaptations produced the diversity seen today. b. species that have gone extinct were able to re-evolve from the ancestors that survived the extinction. c. species that remained after the extinction were unable to speciate. therefore, the number of species on earth today is lower than the number of species present just before either extinction. d. species that remained after the extinction represented all of the lineages that were present before the extinction event. therefore, extinction did not change the diversity of lineages.
