On the other hand, this recourse to gr()und-li\ ing does not recjuireso much in the way of balancing function as in those animals which chpend whollx upon the arboreal highways for their existence. Lidecd, the almost c|uadrupedal locomotion of gorilla would not in itself call for a highlx de\elo|)ed balancing mechanism. Even if the gorilla docs stand upright upon its hind legs at times, it is only poorly adjusted to.
