The Amazing Adaptable Frog

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.

Imagine traveling back through time millions of years to the age of the dinosaurs. Pterodactyls glide above a soggy marsh. Nearby, a colossal 80-ton Brachiosaurus munches on a tree. On the ground at its feet, something strangely familiar hops by: a frog. 

Surprised? Few people realize just how ancient frogs are. For 190 million years, the ancestors of modern frogs have roamed (if not ruled) the earth, looking much the same as they do today. The secret to their success is their amazing adaptability.
