Question

What do scientists think about the common ancestor of whales and hippos? (1 point)
• The animal lived millions of years ago.
• The animal had two limbs.
• The animal is still alive today.
• The animal lived in water.

Answer 1

Scientists believe that the common ancestor of whales and hippos lived millions of years ago and likely had adaptations for both land and water. However, the statement that "the animal had two limbs" may not be entirely accurate, as early ancestors of whales were more adapted for land before they moved to aquatic environments, and their limbs would have evolved differently over time. The correct answer from your options would be:

• The animal lived millions of years ago.
