How does human laughter differ from the play vocalization of most animals?

Question

Human laughter is generally quieter

Human laughter is produced in speech-like pathways in the brain

Human laughter is only used during play

Human laughter does not serve a social function

Answer 1

Human laughter is produced in speech-like pathways in the brain. This distinguishes it from the vocalizations of most animals, which typically do not involve the same complex structures and are often more instinctual or reflexive in nature. While laughter can occur during play, it is not exclusively used for that purpose and does serve important social functions, such as bonding and communication.
