That is why communication is not unique to human beings. Communication encompasses all living beings and pervades the animal world as well.
Birds and animals also communicate. The sounds they make carry meaning. The chirping of the birds, the roaring of the lions, the hissing of the snakes and the whining of the dogs are often meant to be expressive.
Much before they learnt to speak, human beings had learnt to express themselves through sounds, gestures and actions. If we observe closely, we can notice that we continue to use these methods to communicate even to this day. It is not that those who cannot speak, read or write cannot communicate.
A visually challenged person or an illiterate person, resorts to oral and non-verbal communication; while a person with a speech or hearing disability resorts to gesticulations and lip reading. The art of communication has evolved over the years. It goes back in time to the biblical era, mythological times and even to the prehistoric period. People learnt to express themselves even before they evolved fully into their present form.
From sounds, grunts, actions, signs, gestures and gesticulations to the spoken word and thereafter to the world of reading, writing and modern and sophisticated methods of communication, it has been a long yet fascinating and rewarding journey through time. As they progressed on this fascinating journey, human beings learnt to interpret sounds, understand actions and use signs and gesticulations. Messages were conveyed through sounds, cries and drumbeats. The spoken word added a new dimension to the world of learning. Sages and saints of yore learnt to pass on sacred verses and holy texts through word of mouth. Thereafter, human beings learnt to use symbols and pictures to convey messages.
Early writings were on stones and leaves. As human beings progressed, communication evolved further. The invention of printing, as we all know, revolutionized the process of communication. In terms of its reach, the written word signified a quantum leap. Side by side, various inventions made possible the recording of the spoken word and its transmission, irrespective of time and distance. Gradually, the emergence of new media added new dimensions to the world of communication.
Advancements in technology further enabled storage and retrieval of oral and written records in an effective, time-saving and cost- efficient manner.
