Pakicetus is described as an early ancestor to modern whales. These organisms were land mammals, but fossil evidence shows a relation to whales and dolphins based on a number of specializations of the ear related to hearing underwater.
The diagram shows three different skulls in the whale fossil record.
Which additional claim can be BEST supported by the evidence from the skulls in the whale fossil record?
A. The fossil record does not give enough evidence about the mammals to determine if there is a relationship between the three skulls.
B. The fossil record shows similarities in the skulls of the mammals, which shows that they must have had similar habitats and environments.
C. The fossil record shows that some mammals evolved so that their nostrils are further at the top of their skull for better breathing while in the water.
D. The fossil record shows differences in the skulls of the mammals, which shows that they are from three separate species that all lived at the same time.
