uestion 4 n Darwin's mind, the origin of species is inextricably linked to the extinction of species. Why? O New species are better adapted than older species. New species are much better predators than older species. New species kill off the old species. So as new species form, old species are killed off. O New species are better adapted than older species. New species outcompete older forms, causing them to go extinct. So as new species form, old species naturally disappear. O New species mate with older species. This mating merges the two species together. So as new species form, older species merge into them and disappear. O No answer text provided.
