To prevent&nbsp; being killed by a predator or gravity assisted sudden stop. If you were to be thrown off of a tall building , you would fight to put your appendages between you and the ground, even though either way, you will probably be dead at the end. It is the same for cats, insects, amphibians, reptiles, any organism with vision. The brain and the associated sense receptors, with otoliths in skin bladders of fish to otoliths in human ears try to prevents upside-down orientation of the organism. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" />[/QUOTE]</p><p><br /></p>
