Laughter in animals other than humans describes animal behavior which resembles human laughter.
According to Dr. Brian Carroll, self-awareness is conscious concomitant of the physiological processes involving laughter or smiling reflex (response) and its grades, degrees or spectrum varies according to phylogenetic development, with no clear cut demarcation. The emotional ingredients (such as contempt, hatred, ridicule, sarcasm, love, amusement etc.) are variable and involve different neurophysiological and physiological processes.

Famous quotes containing the words laughter and/or animals:
“Turn all her mother’s pains and benefits
To laughter and contempt, that she may feel
How sharper than a serpent’s tooth it is
To have a thankless child!”
—William Shakespeare (1564–1616)
“I wish more and more that health were studied half as much as disease is. Why, with all the endowment of research against cancer is no study made of those who are free from cancer? Why not inquire what foods they eat, what habits of body and mind they cultivate? And why never study animals in health and natural surroundings? why always sickened and in an environment of strangeness and artificiality?”
—Sarah N. Cleghorn (1976–1959)
