Early types of what animals were the first vertebrates that moved onto land and have true lungs, although they had to return to the water to reproduce?

  • Correct Answer: amphibians
  • reptiles
  • mammals
  • birds

Explanation: The first vertebrates moved onto land about 365 million years ago. They were early amphibians. They were the first animals to have true lungs and limbs for life on land. However, they still had to return to the water to reproduce. That’s because their eggs lacked a waterproof covering and would dry out on land.
