Organisms D and C clearly lived in an aquatic (water) environment. Organism A does not look like it lived in the water. What is the most likely explanation for this?

• The fossil in layer A died on land and was carried to the water

• The fossils in layer C and D did not live in the same location as the fossil in layer A

• The environment changed over a long period of time. It used to be under water, but is not anymore

450 million year old rocks contain fossils of jawless fish. 400 million year old rocks contain fossils of jawless fish AND fish with jaws. What does this evidence suggest?
