The fossil of the first fish to walk on land has been found on Ellesmere Island, 600 miles from the North Pole.
Dubbed Tiktaalik roseae, the creature had fish-like bony scales and fins, but also had prototype elbows and wrists as well as primitive fingers.
It took Tiktaalik roseae about 325 million years in order to become Pakicetus and return to the sea as a cetacean.
