Physical anthropologists have discovered what about vocalization in chimp groups It is unique to specific groups or regions.
Like other animals, primates use communication to meet their biological and social needs, which include fending off predators, interacting with other group members, and preserving group cohesion while moving across the environment.
They accomplish this by using a variety of signals, many of which have directly developed as ritualized abridgements of more fundamental physiological or behavioral processes.
For instance, during disputes, chimpanzees may exhibit pilo-erection (bristling of the hair), which gives them the appearance of being bigger and more menacing and indicates their propensity to escalate (van Hooff 1973).
Thus, communication signals have developed to some extent in order to influence recipients mentally (Guilford & Dawkins 1991).
