Paleontologists have found evidence that after a major extinction occurs, there is no particular pattern of speciation many new species

Question

Paleontologists have found evidence that after a major extinction event, there is no specific pattern of speciation, as many new species often emerge around the same time that new species evolve to replace those that became extinct. Most species either adapt or move away because they cannot cope with the changes in their environment. Could you elaborate on this phenomenon and discuss the implications it has for our understanding of evolution and biodiversity after mass extinctions?

Up and downs of biodiversity

The correct answer would be - new species often appear at about the same time.Explanation:A biotic crisis or a mass extinction crisis is a rapid and widespread decrease in biodiversity. There is a clear change after the mass extinction, in the diversity and  of multicellular organisms.Thus, the correct answer would be - many new species often appear at about the same time.

The correct answer is B. Many new species often appear at about the same time Explanation:During Earth's history there have been at least five major extinction during which the biodiversity of Earth declines sharply, this includes the end-Cretaceous extincion, the end-Triassic, the end-Permian, the late-Devonian and the end-Ordovician extinction, although due to limited inforamtion and diferent parametes to categoriza a major extinction it is believed there have been more major extinctions. In all of these cases, after a major extinction occurs the species that survive often diversify and new species of the same kind appear at the same time which implies a peak in speciatio, for example, after the last major extinction mammals experienced a peak in speciation which has been proved through fossils found by paleontologists.
