Answer 1

The ancestor of today's whale had limbs that the modern whale does not have.

Step-by-step explanation:

The ancestor of today's whale had limbs that the modern whale does not have. Fossil evidence found in Pakistan, such as the skeletons of Pakicetus and Rodhocetus, suggests that early whales had hindlimb bones. These bones were likely remnants of their land-dwelling ancestors and were eventually lost as whales adapted to an aquatic lifestyle.
