Obviously one of the characteristics of being a human being is Bipedalism—walking on two feet. Many scientists, infatuated with this hot topic, have made attempts to try to answer the question that people have been debating for years: Is it evolution or God?
In the most recent attempt to find an explanation, researchers trained five chimps to walk on a treadmill while wearing masks that measured their oxygen intake. The chimps were tested on both walking upright and while moving on their legs and knuckles.
The measurement of energy needed was compared with similar tests on humans. And as it turns out, humans walking on two legs use only one-quarter of the energy the chimpanzees use while walking on all fours. On average, chimps use just as much energy using just their two legs, as they did while walking on all fours. David Raichlen, assistant professor of anthropology at university of Arizona, states that one of the chimps used less energy on two legs, one used about the same and the others used more.
“What we were surprised at was the variation. That was pretty exciting, because when you talk about how evolution works, variation is the bottom line, without variation there is no evolution…Walking on two legs freed out arms, opening the door to manipulating the world. We think about the evolution of bipedalism as one of the first events that led hominids down the path to being human.” Though Professor Raichlen has a point, many people believe that they can answer the question many scientists have been asking for years. Their answer? God. Many believe that the reason human beings walk upright is that God made us this way, and the tests performed on chimpanzees mean nothing. In contrast, most evolutionists believe that God plays no part in it, and the reason monkeys walk the way they do, is an effect of adaptation and survival of the fittest, but overall, evolution. So the question still remains if in fact, evolution is the reason human beings walk upright, and as a result use less energy than the chimps who walk on all-fours, or if we have been walking upright since our creation by God.
