Swinging of arms

Hi all,
I have a question. Why do we swing our arms while walking/running? I believe it is involuntary. So, does this have any relation to Evolution ?? Though the way in which the forelegs/hands move varies for different gaits in other animals, can we relate the swinging of our arms to Evolution?

Hi all,
I would like to debate on "Swinging of our arms while walking/running is related to Evolution".
I see a similarity between the way we move our arms while walking and the foreleg motion of Quadrupeds.

Yes. But this is my observation alone. I want to discuss this with the memebers to find out whether this is true or not.

Hi all,
I would like to discuss on the topic " Why are we swinging our arms while walking/running?". From what I have read about the human evolution, Homo genus has evolved from the quadru-pedal movement to bipedal movement through a series of species (like Homo habilis, Homo erectus...). The reason being that the energy spent on bipedal movement is less than that of quadru-pedal motion. We.. Homo sapiens exhibit quadru-pedal movement during childhood (sometime less than 1 year). From the data I have on the evolution of Human brain, the portion of the brain which takes care of the fundamental functions remain same but with some minor differences. So, I guess the part of the brain which issues command for locomotion, still remains differentiably common and hence the movement of our hands, which were forelimbs of some lesser mammals.
