What are tetarpods?

Answer 1

Tetrapods are a group of animals that evolved from lobe-finned fish and are characterized by having four limbs. This group includes amphibians, reptiles, birds, and mammals, representing a significant evolutionary transition from aquatic to terrestrial life. Tetrapods have adaptations such as lungs and limbs that allow them to live on land, although some, like amphibians, still depend on water for reproduction. Their evolutionary history is crucial for understanding vertebrate development and biodiversity.
