Lizard Walking With Two Legs
Posted by Animal King under Lizards
Have you ever seen a lizard that can run on two feet? Scientist Christofer Clemente had seen lizards running with two legs and he tried to figure out why they bother to stand upright if all four legs are functional.
With Philip Withers, Graham Thompson and David Lloyd, Clemente tested how long can lizards run on two legs. The found out that there was no correlation between bipedalism evolution between animals running with two legs. Lizards running with two legs were also not much faster than four, and it required more energy to do so. Scientists guessed that lizards might just be pulling a wheelie by running with two legs.
