The correct answer is (d) - The scientists believe that the common ancestor of whales and hippos lived millions of years ago, and that it was a land-based mammal that eventually returned to the water. There is no evidence that the common ancestor is still alive today. It is also believed that this ancestor had four limbs, although over time, the descendants of this species evolved to have different numbers and shapes of limbs.

Scientists believe that the common ancestor of whales and hippos lived millions of years ago. It is thought to have lived in water and had two limbs. However, it is important to note that this common ancestor is now extinct, meaning it is not alive today.

Scientists believe that the common ancestor of whales and hippos was an aquatic animal that lived millions of years ago. This conclusion is based on extensive research and evidence from the fossil record. By studying the fossils of ancient whale ancestors, scientists have been able to piece together the evolutionary history of these creatures. One key piece of evidence is the presence of similar bone structures and features in both whales and hippos, such as the presence of two limbs. This suggests a shared ancestry and supports the idea that these two groups of animals diverged from a common ancestor that was adapted to an aquatic lifestyle. However, it's important to note that the common ancestor itself is extinct and not still alive today.
