Which is not evidence for evolution?

• many animals have homologous structures due to common ancestry
• Many animals have vestigial structures from an ancestor
• We can observe changes in life forms by observing the fossil record
• All of these are evidence for evolution

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

Which conclusions are best supported by the embryo diagram?

• Organisms develop at similar rates because they share a common ancestor.

• Organisms appear similar in early development because they share a common ancestor.

• Organisms that share a common ancestor develop differently through the three phases of development.

• Organisms that are more closely related develop faster than other organisms due to sharing a common ancestor.
