Question

Paleontologists have found evidence that after a major extinction occurs, _____. there is no particular pattern of speciation many new species often appear at about the same time a new species evolves to replace each species that became extinct most species move away because they cannot adapt

Answer 1

up and downs of biodiversity

Answer 2

The correct answer is B. Many new species often appear at about the same time

Step-by-step 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.
