Darwin Evidence

How do fossils provide evidence that evolution has happened on Earth?

• Fossils show how the sizes of certain animals has changed drastically over millions of years

• Fossils show that some species have gone extinct

• Fossils show how life forms present today are different than those from the past

• Different sedimentary rock layers provide evidence for how the environment has changed over time
