Many fictional characters,specially in the anime art have shoulders bigger than any other upper body muscle. Normally the obliques,chest and latissimus dorsi are the biggest muscles in the upper body but in anime the shoulders are actually bigger than the head.

enter image description here

These are the proportions I'm talking about,normally in humans the shoulders are merely assistance muscles which help the rest of the body on stabilizing the arms, but in anime the rest of the body is an assistance muscle to the shoulders.

Humans who somehow evolved shoulders this big would function differently than normal humans in basic activities or would they just be stronger and no other real difference would be noticed?

  • Shoulder dislocation would be less common, although reducing the dislocation would be much harder.
  • If women do not evolve with larger hips and broader vaginal canal, there will be more deaths during labor, affecting both mother and child. That could result in more caesareans.
  • More strength on the upper body, although if other muscles do not evolve similarly, there won't be much difference since you need muscle synergy.
  • Less mobility since you won't have much range of motion of the upper limbs.
  • Larger seats so you could sit comfortably not rubbing shoulder to the person next to you.
  • Scratcher would be a well paid profession, since you can't reach your back. Ok that one is a joke, but you get the idea.

Nothing Interesting

If it's happening through evolution, then the selection underlying this muscle growth would also select for the best support mechanisms for it, ie more muscular backs, bigger abs, bigger bones in the back and shoulders. Modern bodybuilders get close to anime proportions with minor negative effects on their bodies, like reduced flexibility. Assuming that that the evolved humans increase the size of their shoulders to gigantic proportions through training, we can look to body building to get an idea of what might happen. Otherwise, the only noticable effect would be increased vertical lift strength when using the arms, since that's how the muscles in the shoulders are set up to work.
