ELI5: Why does everyone have a unique gait when biologically most of us are all pretty similar? I've read that it's on par with a person's iris in terms of uniqueness.

Thanks for the silver kind stranger!

Your gait is super-heavily influenced by the size, shape, and mass distribution of your entire body. You are basically a stack of pendulums on top of another, upside-down pendulum, and since every part of you is connected to every other part, your organs' momentum pulls on everything. Something off about your shoulder might change how you move your arms, which changes how you move your feet in order to compensate. Even subtle differences exponentially compound just because of how complex people are.
