By the way, so stark, what made that our body could move itself only to our intentionally heading direction and only for it, our body structure had been given in conditioned that our the backborn as spinal column was fixed at regulatory part and we only could face our fore body to heading direction?

Necessarily that was merely accidentally done. Because that must have been what our nature merely was given.

Nevertheless, if we try to analyze and interpret according to natural selection, that could be rationally explained so well like next.

If our body could have been given the condition that our whole body parts could move to any direction only for protecting own body from being injured at attacking by any other individual body, that body biologically inherently given body holding species must have only mutually hostile relevant harshly violent survival competitive society at biological term.

Meanwhile, our really given condition is in fact made at being versatile for taking our mind to cooperate any necessary working mission, because mutually only one direction fixed the backborn and neck's heading direction only for adapted for mutually easily communicate with each other in the same species.

And if that first fixed condition in which any individual body was fixed at one fore heading direction was set to our surviving reality, that form given reality could be in fact given a possibility to get its form reformed according to natural selection's necessary given principle at each necessarily emergency reactive occasion.❇️

In other words, natural selection's stepping must go ahead for only minimally necessarily objected direction, not depending to the highly evolved conditioned at the utmost precisely emergency reactive necessity.

Consequently, natural selection's very basic mechanical structural nature must depend on very simply adaptable practical object and usage at usually frequently necessary condition.

And in applying first given condition and in long period's the first naturally given condition applicable running, gradually facing unnecessary taken situation could have been learnt in statistical naturally learning mechanism each individual body congenitally given as first initial setting condition, in naturally mechanically learning mechanism as physiological necessity, otherwise life species time record or own mechanical memory could have been mobilized to practical usage abiding direction.
