Francis Hutcheson in Thoughts on Laughter (1725) was the first modern thinker to account for humor by the term "incongruity," which became a major concept in the evolution of this field. [25] In this early version, incongruity was mostly a singular clash between two opposing ideas.
Laughter in animals other than humans describes animal behavior which resembles human laughter. Several non-human species demonstrate vocalizations that sound similar to human laughter. A significant proportion of these species are mammals, which suggests that the neurological functions occurred early in the process of mammalian evolution. [ 1 ]
Laughter is a pleasant physical reaction and emotion consisting usually of rhythmical, usually audible contractions of the diaphragm and other parts of the respiratory system. It is a response to certain external or internal stimuli. Laughter can rise from such activities as being tickled, [1] or from humorous stories, imagery, videos or ...
Evolutionary theorists have attempted to study and explain the phenomena of laughter and humor in terms of survival benefit. Laughter-like behavior is not unique to humans, but humans do display a much more consistent and complex use of humor and laughter than other animals. [ 6 ]
The study of the evolution of emotions dates back to the 19th century. Evolution and natural selection has been applied to the study of human communication , mainly by Charles Darwin in his 1872 work, The Expression of the Emotions in Man and Animals . [ 1 ]
Humour (Commonwealth English) or humor (American English) is the tendency of experiences to provoke laughter and provide amusement.The term derives from the humoral medicine of the ancient Greeks, which taught that the balance of fluids in the human body, known as humours (Latin: humor, "body fluid"), controlled human health and emotion.
In its public management, Darwin understood that his evolutionary theory's relevance to human emotional life could draw an anxious and hostile response.. While preparing the text of The Variation of Animals and Plants Under Domestication in 1866, Darwin began to explore topics related to human ancestry, sexual selection, and emotional life.
Humans have a unique allele of this gene, which has otherwise been closely conserved through most of mammalian evolutionary history. This unique allele seems to have first appeared between 100 and 200 thousand years ago, and it is now all but universal in humans. [10] This suggests that speech evolved late in the overall spectrum of human ...
