THE NEED TO COMMUNICATE:
Since the appearance of primitive humans, sixty-five million years ago, communication has been a necessity that has evolved alongside human history. As humans began to create tools, including some for warfare, they invented others to generate alert sounds for their tribe or group. With the discovery and mastery of fire, smoke signals were used for long-distance communication. The earliest drawings appeared in cave paintings, leaving us a message through time about how humans survived danger and obtained food. Written words in books, particularly with the invention of printing, allowed us to access knowledge and experiences from past eras or distant lands. Body signals, such as hand gestures or the emission of natural sounds, were part of the earliest person-to-person communications due to the human need to connect with their environment. Curiosity led humans to discover, develop, and transmit knowledge, giving rise to the constant need to communicate with others.
