When did communication start? Did it start with the advent of writing? Or the development of spoken word? Are humans to credit for communication as we know it, or does it pre-date our species?
Realistically, there’s no way know the origins of communication. How would we measure it? What constitutes communication, and what does not?
The oldest known symbols created for the purpose of communication were cave paintings dating to the Upper Paleolithic age, with the oldest examples located within Chauvet Cave in France, and dated to approximately 32,000–30,000 years before present.
The local Sinixt pictographs along the Arrow Lakes have been relatively dated back thousands of years.
In the 1830s electrical telecommunication systems started to appear, and since the advent of the Internet, mobile networks, and cellular phones communication has exploded into what we know today.
