When we realize that the wheel is one of the few technical devices which in the organismic world are not at least indicated, then this is perhaps not in the last place connected with the fact that such a device is incompatible with a unimolecular total-bonding [a chemical bond may be able to twist, but not turn full circle and beyond], while a system-view leaves open (much more surprising realizations do occur [in the organismic realm] ) the possibility to maintain [in such rotating wheel], from the [stationary] axis of rotation, the necessary serous contacts [i.e. contact through a liquid serum-like medium] for feeding and innervation [of the wheel]. Of course, the absence of wheels in organisms is not proof of the correctness of Unimol, but perhaps an indication of specifically why the wheel cannot be realized at all.
