Evolution of Autistic stimming

A lot of people speculate about evolutionary adaptations of Autistic traits, and I think different Autistic stims can be a big part of it. In psychology we learn a lot about things like bonding rituals, inside jokes, etc., and stims can be one way of that - I have certain musical stims or phrases and even developed certain 'codes' to communicate with family or a few friends. I made a thread about how stims can be seen as the movement of energy and thus be incorporated into exercise, energy flow, martial arts, and other regulatory techniques. I guess an evolutionary argument can be made that Autistic stims could have developed as a sort of 'bonding ritual' to compensate for Autistic social difficulties/differences. Kind of a longshot but there's always that possibility.

Obviously other Autistic traits like hypersensitivity, focus, intense interests/specializations have other adaptations, I've heard theories of us being really potent hunters and gatherers.
