Human communication was initiated with the origin of speech approximately 100,000 BCE. [1] Symbols were developed about 30,000 years ago. The imperfection of speech allowed easier dissemination of ideas and eventually resulted in the creation of new forms of communication, improving both the range at which people could communicate and the longevity of the information.
