Answer:

They are both vertebrates that lay eggs to reproduce.

Explanation:

Amphibians and reptiles both are vertebrates and lay eggs to in order to reproduce & they both belong to kingdom Animalia. Evolutionarily reptiles are considered more advanced than amphibians but still they both share some common characters like having a vertebral column and being oviparous i.e. laying eggs to reproduce rather than giving birth to young ones directly (viviparous). Amphibians are the pioneers of terrestrial animals. Unlike fish which are also a member of kingdom Animalia and are bound to be in water in order to survive, amphibians can come out of water. Likewise reptiles can also live in land as well as water.
