Do animals laugh like humans?

Answer

So far, no one has seen any evidence that any animal laughs

Laughter is a rich experience and expresson in human beings. Thus there are several shades of smiling and laughing expressions. They involve elaborate neurophysiological and physiological processes. Such laughter is not seen in animals. But one can not deny occurence of primitive prototype of "laughter" in terms of experience and expression in animals. Owners of pets can vouch on this point, if they understand when their pet is happy and how it expresses the same.

According to Dr. Shriniwas Kashalikar, "self awareness" is conscious concommitant 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.

Self awareness and ability to identify with another's predicament may be prerequisite to intellectual jokes with specific references and contexts, but not for laughing behaviour as such.
