Human beings walk upright, on two legs, using a special movement not encountered in any other living thing. Some mammals may have a restricted ability to move on two legs, such as bears and apes, and stand upright on rare occasions for short periods of time, such as when they wish to reach a food source or scout for danger. But normally they possess a stooped skeleton and walk on four legs.
However, bipedalism (walking on two legs) did not evolve from the four-legged gait of apes, as evolutionists would have us believe.
First off, bipedalism establishes no evolutionary advantage. An ape’s mode of walking is easier, faster and more efficient than a human’s. Human beings cannot move by leaping from branch to branch like apes, nor run at 125 kilometers/hour (77 miles/hour) like cheetahs. Since they walk on two legs, humans actually move very slowly over the ground, making them one of the most defenseless creatures in nature. According to the logic of evolution, there is therefore no point in apes “evolving” to walking on two legs. On the contrary, according to the survival of the fittest, human beings should have begun walking on four.
Another dilemma facing the evolutionists is that bipedalism is wholly incompatible with Darwin’s model of stage-by-stage development. This model suggested by evolution presupposes some “compound” form of walking, both on four and two legs. Yet in his 1996 computer-assisted research, the British paleoanthropologist Robin Crompton showed that such a compound walking style was impossible. Crompton’s conclusion was that “a living being can either walk upright, or on all fours.” A walking style between these two would be impossible, as it would consume too much energy. Therefore, it is impossible for any semi-bipedal life form to have existed.
