Which pattern is evidence dat reptiles and amphibians share da same ancestor?

Question

A ) They hve legs

B ) They hve bck bones

C ) They hve eyes

D ) They hve similar skin

Answer 1

The correct answer is B) They have back bones.

Both reptiles and amphibians are vertebrates, meaning they possess a backbone, which is a significant piece of evidence that they share a common ancestor. While they may have other characteristics in common, such as having legs or eyes, these traits do not specifically indicate a shared ancestry as directly as the presence of a backbone does.
