Evolution and the Fossil Record Quiz

What is the primary significance of the fossil record in the study of evolution?

• It provides evidence of the past organisms that are no longer living.

• It shows the direct genetic relationships between all living organisms.

• It can be used to predict future evolutionary trends.

• It offers a detailed history of human evolution only.

Which of the following best describes the principle of superposition?

• Younger layers of rock are deposited on top of older layers.

• Fossils can float between layers, making dating them impossible.

• The oldest fossils are found on the top layers of rock.

• Rock layers are always found in the same order everywhere on Earth.
