Scientists examine fossils from three different animals. They determine that all three animals share similar structures and record their observations as follows
• Animal A and animal B have somewhat similar structures
• Animal A and animal C have very similar structures
• Animal B and animal C have very similar structures
The scientists use the similarities to determine the order in which the fossils should appear in the fossil record. Based on the
scientists' observations, which order is the most reasonable?
