time line

Communication starts from the day when Human don't know how  to speak.They communicate in different ways.

Primitive times:

Human communication was revolutionized with the Origin of speech approximately 500,000 BCE. Symbols were developed about 30,000 years ago.

Petroglyphs:

The next advancement in the history of communications came with the production of petroglyphs, carvings into a rock surface. It took about 20,000 years for homo sapiens to move from the first cave paintings to the first petroglyphs, which are dated to approximately the Neolithic and late Upper Paleolithic boundary, about 10,000 to 12,000 years ago. 

Pictograms:

Pictograms were used by various ancient cultures all over the world since around 9000 BC, when tokens marked with simple pictures began to be used to label basic farm produce, and become increasingly popular around 6000–5000 BC.

Ideograms:

Pictograms, in turn, evolved into ideograms, graphical symbols that represent an ideas.

Writing:

The original Sumerian writing system was derived from a system of clay tokens used to represent . By the end of the 4th millennium BC, this had evolved into a method of keeping accounts, using a round-shaped stylus impressed into soft clay at different angles for recording numbers. This was gradually augmented with pictographic writing using a sharp stylus to indicate what was being counted. Round-stylus and sharp-stylus writing was gradually replaced about 2700–2000 BC by writing using a wedge-shaped stylus (hence the term cuneiform), at first only for logographys, but developed to include phonetic elements by the 2800 BC. About 2600 BC cuneiform began to represent syllables of spoken Sumeria language.
