THE NEED TO COMMUNICATE:
Human beings have needed to exchange signals and auditory gestures for their social interaction since primitive times. Along with their evolution as a species, communication has been part of their primary development. Initially, it was to interact for the purpose of reproduction, and later for hunting and survival, as well as interacting with the rest of their group. During their nomadic and later sedentary survival, along with the mastery of fire, as they sought to establish communal settlements, they left traces of pictograms that we now call cave paintings. These are the first evidence of how humans perceived their world and left a mark for posterity, communicating to us what happened during those times. This enabled the transmission of knowledge.
