• homologous structures

• Charles Darwin

• the fossil record

Which layer is the youngest

• 1
• 2
• 3
• 4

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

Similarities in bone arrangements, like those in the picture, support the hypothesis that...

What is this an example of?
