Similar structures with different purposes found in different species are known as _____

• vestigial structures

• DNA

• homologous structures

• the fossil record

The picture shows a/an ___________

• Have very similar skeletal structures
• belong to the same species
• must range great distances to eat

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
