Scientists excavated a skull fossil that provides evidence of newly discovered species of big cat. Based on the evidence, scientist hypothesize that big cats branched off from smaller wild cats about 6 million years ago.

Which of these resources did the scientists most likely rely on to form their hypothesis?

• A food web showing feeding relationships

• Population data

• The fossil record comparisons of big cats and small cats

• The historical record of interactions

These provide evidence of common ancestry because

• they have the same basic structure

• perform the same function

• are the same size

• are parts of mammals
