When did frogs evolve? Frogs developed out of lungfish about 375 million years ago, in the Devonian period. They used their lungs to leave the water and live on land.

What species did frogs evolve from?

Ichthyostega, prehistoric predecessor to the modern frog, lived 370 million years ago during the Devonian Period. Sometimes referred to as "the first four-legged fish," skeletal remains of this earliest-known amphibian were first discovered in East Greenland.

What are frogs descended from?

Robert Reisz of the University of Toronto and Nadia Fröbisch, a PhD candidate at McGill University's Redpath Museum and colleagues, have proven conclusively that all modern frogs, toads and salamanders descend from a common amphibian ancestor that existed over 200 million years ago.
