Scientists believe that the common ancestor of whales and hippos was a land-dwelling animal that had four limbs. However, research has shown that this ancestor gradually transitioned to an aquatic lifestyle, eventually evolving into modern whales. Therefore, the common ancestor of whales and hippos is now extinct and lived millions of years ago.
