Whatever its origins may be, laughter seems to be a uniquely human trait. The ancient Greek philosopher Aristotle asserted that laughter — not speech, conscious thought, culture, or opposable thumbs, which give us the ability to grasp objects — is the most important trait separating human beings from wild beasts. While many animals make sounds that resemble laughter, those sounds are not an expression of mirth or merriment. Laughing hyenas, for example — despite their name — do not really laugh. The high-pitched sounds they emit are triggered not by something funny but because they are excited or on the prowl.
