What do scientists think about the common ancestor of whales and hippos
1. the animal is still alive today
2. the animal lived in water
3. the animal lived millions of years ago
4. the animal had two limbs
1. Scientists do not believe that the common ancestor of whales and hippos is still alive today. The common ancestor is believed to have lived millions of years ago.
2. It is widely accepted that the common ancestor of whales and hippos evolved to live in water. This is supported by fossil evidence and comparative anatomy studies.
3. Scientists agree that the common ancestor of whales and hippos lived millions of years ago. Based on the fossil record and molecular studies, they estimate that this ancestor lived around 50 million years ago.
4. The common ancestor of whales and hippos is believed to have had four limbs, as is typical for land-dwelling mammals. Over time, as they evolved to adapt to aquatic environments, whales lost their hind limbs while hippos retained all four limbs.
