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?

Welcome to EvC
Welcome to EvC Karthikeyan,
Thank you for proposing a new topic and adding to our diversity. Since you are new to EvC, I suggest that you carefully read the Forum Guidelines and familiarize yourself with the functions of EvC by using the Practice Makes Perfect Forum or posting in existing threads.
You have two questions here. "Why do we swing our arms while walking/running?" and "Can we relate the swinging of our arms to evolution?"
Do you want to debate whether swinging our arms while walking/running is voluntary or involuntary or whether the action is related to evolution or not?
An opening post should consist of the topic question or statement being considered and the poster's own position concerning the subject with support for that position.
I suggest that you rewrite your opening post to clarify what you want to debate. Let me know when you want me to review your post again by replying to this post using the little green reply button at the bottom right of this message.

Again welcome and fruitful debating. Purple

    Hello Admin,
    I'm rewriting my topic. Please take a look at it.

    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.

    Re: Welcome to EvC
    So your position is that it is related to Evolution, correct?
    What point are you wanting to make with this discussion?

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

    Re: Welcome to EvC
    I understand that, but could you elaborate and put more substance in your opening post? At least a good paragraph or two.
    Give them an idea of what prompted your interest and/or what research you've already done.

    Hello Admin,
    I'm rewriting my post again:
    ########################################################################
    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.
    ####################################################################
    Please comment on this.
    Edited by AdminPD, : No reason given.
