Explanation:
Detailed explanation-1: -Fossils. Fossils document the existence of now-extinct past species that are related to present-day species.
Detailed explanation-2: -The extinction of species (and larger groups) is closely tied to the process of natural selection and is thus a major component of progressive evolution. In some passages of the Origin, Darwin seems to have seen extinction as part of natural selection; in others, as an inevitable outcome.
