Document Summary
Although nonhuman primates lack the language systems of homo sapiens, all nonhuman primate species make use of communication systems, which can include vocalizations, facial expressions, body postures, and scent marking (olfactory communication), allowing for considerable social complexity. Male hanuman langurs exhibit a whoop vocalization as a form of inter-group display: female grooming a large male, the tilted head posture of the male is a typical grooming invitation signal seen in many nonhuman primates. The lip-flip of geladas is an agonistic signal unique to this species. The open-mouth threat is an agonistic signal that is seen widely across the order. Primates: nwm (like white-faced capuchins, lion-tailed macaque,, male celebes black crested macaque, owm like mandrill, apes (humans) Humans and nonhuman primates (like crab eater macaques) share many facial expressions: bare teeth, signal for fear and submission (provoked and unprovoked situations). The lip smack shows affiliation between interaction partners.
