The brain doesn't start out knowing what body it is attached to, so it learns it. This is why having six-fingered hands produce extra neural representations (and can boost manipulation ability):https://www.nature.com/articles/s41467-019-10306-w …

It seems that people with different numbers of digits develop five fingered phantom limbs when they lose a hand. Our models of the world are probably built on evolved priors as well.

I would expect evolution to give us innate biases that make adapting to near-standard bodies as quick and easy as possible without giving up flexibility for non-standard bodies.

Exactly. I suspect that messed up priors in the social and self regulation domains require development of explicit reasoning, which helps breeding scientists...
