According to a report in the Live Science, The Christian Science Monitor, scientists have discovered air-breathing lungfish that has an eel-like body and a pair of flimsy hind fins, can lift its body clear off the bottom and hop and walk across the floor on their fins.
Researchers and biologists at the University of Chicago said that this display of primitive walking behaviour suggests that walking may have evolved underwater before such animals began migrating on to land since the distant ancestors of humans and all mammals, reptiles, birds, amphibians and other four-limbed animals, or tetrapods are fish that eventually developed the ability to breathe on land..
Live Science also reported that this discovery of the walking lungfish found, in Africa, South America and Australia, might redraw the evolutionary route scientists think life took from water to land. Many of the steps needed to adapt to surface-dwelling could have occurred millions of years before early tetrapods developed limbs with digits and took their first steps on shore.
