Question

Salamander and frog both are amphibian. Which one came first in evolution

Answer 1

Answer:

Now a Texan fossil, Gerobatrachus hottoni ("Hotton's elder frog") from around 300 million years ago, proves the previously disputed fact that some modern amphibians, frogs and salamanders evolved from one group of ancient primitive amphibians called temnospondyls, some of which were up to 1.5 metres long.
