Do Snakes Have Legs?

Fossil evidence suggests that snakes may have evolved from burrowing lizards. Hunting in tiny burrows and tunnels would have favored streamlined animals, with narrow pelvic bones and smaller legs. Eventually, legs would have been more of a hindrance than an advantage. There is dispute in the scientific community about whether snakes evolved from terrestrial lizards or marine reptiles, but the evidence clearly indicates that proto-snakes had legs.
