Amazing experiment -
Cookies must be enabled. The Australian
THE emergence of fish on to land was a pivotal transition in evolution. Now scientists have attempted to re-create it in a remarkable experiment, in which 100 fish were reared from birth on land. The study used an African fish, the polypterus, that has lungs and can “walk” between pools, but normally spends its entire life in water. The creatures survived “happily” out of water for nearly a year, suggesting ancient marine creatures may have made the leap to land more readily than previously thought.
