Detailed explanation-1: -5. Fossils of marine organisms high in the Andes Mountains led Darwin to conclude that geologic change had occurred/major changes occur over time/changes take a long time to occur. 6. Some organisms that share a common ancestor have features that have similar structures but different functions.

Detailed explanation-2: -According to Charles Darwin, the fossil record documents the evolution of species throughout the earth’s history. More specifically, the fossil record suggests that species can and do change through time.

Detailed explanation-3: -He learned from the finches that there is variation among a species in different environments. On his voyage, Darwin observed fossils of extinct organisms that resembled living organisms. He also found shells of marine organisms high up in the mountains.

Detailed explanation-4: -Scientists had been debating whether animals evolved decades before Darwin put forth his theory. The idea of “transmutation of species” had been rejected by many prominent naturalists, among them French scientist Georges Cuvier, who believed that species had been created much as they appeared in his day.

Detailed explanation-5: -The correct statement is e. Only populations evolve, individual organisms do not.
