The following outline is provided as an overview of and topical guide to prehistoric technology. Prehistoric technology – technology that predates recorded history. History is the study of the past using written records; it is also the record itself. Anything prior to the first written accounts of history is prehistoric (meaning "before history"), including earlier technologies. About 2.5 million years before writing was developed, technology began with the earliest hominids who used stone tools, which they may have used to start fires, hunt, cut food, and bury their dead. == Nature of prehistoric technology == Prehistoric technology can be described as: * Prehistoric – "before we had written records," from the Latin word for "before," præ. Prehistory is the span of time before recorded history, that is, before the invention of writing systems. * Technology – making, modification, usage, and knowledge of tools, machines, techniques, crafts, systems, and methods of organization, in order to solve a problem, improve a preexisting solution to a problem, achieve a goal, handle an applied input/output relation or perform a specific function. 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「Outline of prehistoric technology」の詳細全文を読む スポンサード リンク
