Here is the correct answer of the given question above. The lack of legs is a primitive characteristic for amphibians. The first amphibians to spend a significant part of their life on land most likely evolved from lobe-finned fishes. Lobe-finned fishes ancestral to amphibians had a bone structure within their fins that worked as legs that could walk on land. Hope this is the answer that you are looking for.
