During which period of the Paleozoic Era did the first amphibians evolve?

A. Permian

B. Devonian

C. Cambrian

D. Carboniferous

The correct answer is option B. Devonian.

The amphibians are the tetrapods (having four limbs), which can live in both water and land, but for reproduction purpose, they need water and early life is exclusively aquatic. The amphibians are known to be evolved from lobbed finned fishes around 370 million years ago in the Devonian period of the Paleozoic Era.
