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.
