Human communication was revolutionized with speech approximately 500,000 years ago. Symbols were developed about 30,000 years ago,〔 and writing about 5000 years ago. ==Symbols== The imperfection of speech, which nonetheless allowed easier dissemination of ideas and stimulated inventions, eventually resulted in the creation of new forms of communications, improving both the range at which people could communicate and the longevity of the information. All of those inventions were based on the key concept of the symbol: a conventional representation of a concept. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「History of communication」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
