Question

Early land animals had gills as well as lungs. Please select the best answer from the choices provided T F

Answer 1

The answer is true, because when the land animals evolved, they originally came from the oceans and lakes as water animals, so therefore they had gills. But when they evolved, they had lungs to.

Answer 2

The answer is False.

Although, there are some evidence that suggests that species from million years ago possessed both gills and lungs. For example is the Acanthostega Gunnari, one of the oldest species discovered with four limbs. The creature is a salamander-like creature found in Greenland hundreds of million years ago. Although the specie can walk on land but the finding characterized the creature primarily as a fish.
