How do fossils help scientists understand the history of life on Earth?

• By providing a complete record of every species that ever lived.

What is the significance of finding similar fossils in different layers of rock?

• It indicates that the species lived for a long period of time.

• It suggests that the species was very mobile.

• It shows that the species was very large.

• It proves that the species was very rare.
