Walking while swinging arms is not part of human evolution

Walking like clownI am not sure, but evolution theory said we inherited traits of ape, that's why we swing our arms forward when we are walking. Steven Collins, a biomechanical engineer at Delft University of Technology discovered, that this is a more efficient way of walking. Not only we cannot balance, but we will use up 25% more energy to walk without swinging our arms. Off course this make sense, or else we would have urge to pick up a cup with our leg from time to time.

Good news for those slim down wanna-be. Try walking while keeping your hand still. Tell me the result if nobody laugh at you.
