Scientist examine fossils from three different animals. They determine that all the animals share similar structures and record their observations as follows animal a MOV has some similar structures, animal and animal C, have very similar structures animal be an animal see have very similar structures, the scientist use similarities determine the order in which the fossil should appear in the fossil record based on the scientist observations which order is the most reasonable.
Based on the scientist's observations, the most reasonable order for the fossils to appear in the fossil record would be:
Animal A --> Animal C --> Animal B --> Animal D
