When did the first amphibians come ashore?
about 340-360 million years ago A new study of early amphibians suggests that movement from water to land and back again left an impression — on the shape of the animals’ spines.

From which group of fish did amphibians evolve?
Sarcopterygii amphibians evolved in the mid-Devonian (416–359 million years ago) from the lobe-finned fishes of the vertebrate class Sarcopterygii. Species within the genus Ichthyostega (members of the subclass Labyrinthodontia) are considered by some scholars to be the earliest amphibians.

What do amphibians do that fish don’t?
