Fish out of water

Around 400 million years ago, fish left the water and started to  evolve into land-loving creatures. But how did the transition happen? A new and unusual experiment could shed some light on the kinds of changes that enabled fins to become limbs. Researchers took a fish species known to be able to walk on its fins from time to time, and raised it on land. Watch the fish promenade in this Nature Video.
