Language is a complex system that arose from the animal cognitive system and not from animal communication, which suggests that only humans with a complex brain system were able to develop (Ulbaek, 1998). While other animal species communicate through vocalized sounds, songs or gestures, especially primates like monkeys. Similarly, gestures and hand gestures were the form of communication used by early hominids, but Homo habilis and Homo erectus began to use vocalizations and decreased the frequent use of simple hand gestures for communication . Humans have evolved a spoken language system used to express separate and distinct thoughts. Others have suggested and supported that language evolved through imitation of sound in the environment and have identified the vocal apparatus that humans require for spoken language (Fitch & Reby, 2001 ). However, there is no direct evidence and if one wants to study the origins of language, one must rely on other types of evidence such as fossil records or archaeological studies. This essay will present the main theories and explain the origin of language drawing on studies from various methodologies such as anthropology. Symbolic sounds developed from the cries that primates used to alert each other of danger may have been the starting point for human language. as well as the physical modulations necessary for speech. As cited by Sabbatini (2001) “human language is the result of a complex interaction between thousands of brain areas and structures, neural mechanisms of perception and action, muscular activity, breathing…” This quote suggests that vocal language is a complex process that involves many cognitive processes and muscular activities, particularly in the mouth and phar...... middle of article......_10_s_lan/d_10_s_lan.htmlPollick, A. & Waal, F.
