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.
