"We humans are no match for the lion in strength; outstripped by the ostrich in speed; win no medals against the dolphin in swimming; can smell less acutely than the dog; cannot see as well as the hawk during the day, or the cat at night.  Yet, as far as we know and understand, it is the human species that excels in the use of symbols.  The sending and receiving of sophisticated messages set us apart from all other creatures on earth".
