Apes, Walking, and Evolution
Humans were built with a very efficient system for walking upright and keeping balance. The rib cage, pelvis, arm swing, muscles, bones, all of those things work together to keep us going and not falling. Walking changes when you're packing a firearm because it changes your gait and arm swing. For that matter, cowboy boots make me walk differently than my loafers. If you've a mind to, pay attention to your walking (or get someone else to do it so you can watch) when wearing different shoes. The point is that our system is very precise.
People with the viewpoint that ancestors of humans and apes swung down from the trees way back when are all fired determined to think that humans are really not so special, not created by God, but by chance and things. Chimpanzees and gorillas are built radically differently than humans, and bipedal locomotion is difficult for them, but moving on all fours is efficient. (One way to usually tell when someone is in a gorilla costume is that the sway they need to use is difficult for a human to imitate convincingly. Another way to tell is the eyes that look human. Also, if he asks for help getting out of the costume, that's a dead giveaway.) But some evolutionists keep trying overmuch to think that by studying chimpanzees that exist today, then examining bones of extinct knuckle-walkers like "Lucy", they can determine what happened in the distant past.
What can chimps strolling down a walkway tell us about how humans learned to walk on their own two feet? More than previously thought, claim the evolutionary authors of a study recently published in Nature Communications.To take steps to read the rest of the article, click on "Did Humans Walk Like Chimps Up the Evolutionary Tree?"
Hercules and Leo, the two chimps who learned to walk upright for this study in their Stony Brook University laboratory home . . . have supposedly shown Stony Brook researchers clues about how humans evolved the ability to walk.
