Science's Presuppositions Proven Wrong

"PARIS (AFP) – Biomedical researchers on Wednesday said they could explain why we swing our arms when we walk, a practice that has long piqued scientific curiosity.
Swinging one's arms comes at a cost. We need muscles to do it, and we need to provide energy in the form of food for those muscles. So what's the advantage?
Little or none, some experts have said, contending that arm-swinging, like our appendix, is an evolutionary relic from when we used to go about on all fours.
But a trio of specialists from the United States and the Netherlands have put the question to rigorous tests."

"Arm-swinging turned out to be a plus, rather than a negative, the investigators found.
For one thing, it is surprisingly, er, "'armless" in energy costs, requiring little torque, or rotational twist, from the shoulder muscles.
Holding one's arms as one walks requires 12 percent more metabolic energy, compared with swinging them.
The arms' pendulum swing also helps dampen the bobbly up-and-down motion of walking, which is itself an energy drain for the muscles of the lower legs.
If you hold your arms while walking, this movement, called vertical ground reaction moment, rises by a whopping 63 percent."

" 'Rather than a facultative relic of the locomotion needs of our quadrupedal ancestors, arm swinging is an integral part of the energy economy of human gait,' says the paper."

Imagine that. God knew what He was doing when He created us, along with the entire universe.
Creation gets easier to believe than Evolution all the time. Thank you science! Thank you scientists! Keep up the good work!
