Abstract
A kiss has been a signal of special affection across continents and cultures for millennia. Between times and peoples, social norms invariably prescribe kissing to specific affiliations and contexts, implying deeper biological bases. Why the protruding of the lips and slight suction when touching another? Capuchin monkeys stick their fingers in their friends' eyes as sign of affection, why have humans developed kissing? Here I briefly review proposed hypotheses for the evolution of human kissing. Great ape social behavior suggests that kissing is likely the conserved final mouth-contact stage of a grooming bout when the groomer sucks with protruded lips the fur or skin of the groomed to latch on debris or a parasite. The hygienic relevance of grooming decreased over human evolution due to fur-loss, but shorter sessions would have predictably retained a final "kissing" stage, ultimately, remaining the only vestige of a once ritualistic behavior for signaling and strengthening social and kinship ties in an ancestral ape.
期刊介绍:
Evolutionary Anthropology is an authoritative review journal that focuses on issues of current interest in biological anthropology, paleoanthropology, archaeology, functional morphology, social biology, and bone biology — including dentition and osteology — as well as human biology, genetics, and ecology. In addition to lively, well-illustrated articles reviewing contemporary research efforts, this journal also publishes general news of relevant developments in the scientific, social, or political arenas. Reviews of noteworthy new books are also included, as are letters to the editor and listings of various conferences. The journal provides a valuable source of current information for classroom teaching and research activities in evolutionary anthropology.
