A crucial fossil that shows how animals crawled out from the water,
evolving from fish into land-loving animals, has been found in Canada.

Creatures with features of both fish and land-living animals have been
found before. Fish that may have been beginning to 'walk' in shallow water
have been found from about 385 million years ago, and fish with limbs that
bear digits have been seen from more than 365 million years ago.

Specimens that fall into the gap, such as Tiktaalik, help researchers to
work out the details of this transition. The newly found animal has a
structure on its head that looks like a small gill slit that is on its way to
becoming an ear, for example, and a long snout that would have been
suited to catching prey on land.
