The chimp results were compared to four humans walking upright on the treadmills.Results showed that for a given weight, humans used only one-quarter of the energy as the chimps. 2) … The chimp results were compared to four humans walking upright on the treadmills.
“It measures how much force is being applied by the limb to the ground.”Biomechanical equations predict that energy consumption increases either with shorter steps or more active muscle mass.

However there are some good theories that are interesting to chew over.There are probably over a dozen theories that had been put forward over the last century or so. Its base is strong and able to withstand the stresses of walking and running.The chimpanzee knee joint is lightly built, so chimpanzees cannot rest their weight on one leg at a time to walk for long periods.The early human knee joint was strong, enabling this early human to regularly support its weight on one leg at a time during walking.Strong knee joints help support your body’s weight on one leg at a time while walking long distances.As environments changed, walking on two legs helped early humans survive by:Back pain and other skeletal problems are relatively common in modern humans, an unfortunate side effect of walking upright. Walking upright on two legs is the trait that defines the hominid lineage: Bipedalism separated the first hominids from the rest of the four-legged apes. As a result, they could take advantage of both habitats.The curve of your lower back absorbs shock when you walk. This was a reasonable conclusion since the only known hominid fossils were of brainy species–Neanderthals and That thinking began to change in the 1920s when anatomist Raymond Dart discovered the skull known as the In more recent decades, anthropologists have determined that bipedalism has very ancient roots.

Which is true, but also irrelevant: the point is that a bipedal human is more energy-efficient than a human forced to get around on all fours. ""Shaping Humanity: How Science, Art, and Imagination Help Us Understand Our Origins" (book by John Gurche)What Does It Mean To Be Human? You can see a similar curve in the spine of this early human, Modern chimpanzees occasionally walk upright, but their skeletons are not adapted for regular walking on two legs. The reason humans walk upright might be because we learned not to drag our bodies in cold, wet snow.
