Fish Raised On Land Give Clues To How Early Animals Left the Seas

sciencehabit writes When raised on land, a primitive, air-breathing fish walks much better than its water-raised comrades, according to a new study. The landlubbers even undergo skeletal changes that improve their locomotion. The work may provide clues to how the first swimmers adapted to terrestrial life. The study suggests that the ability of a developing organism to adjust to new conditions—its so-called developmental plasticity—may have played a role in the transition from sea to land.
