STONE AGE  ~2,6 million years

The Stone Age is a broad prehistoric time period during which humans widely used stone for toolmaking.

Stone tools were made from a variety of different kinds of stone. For example, flint and chert were shaped (or chipped) for use as cutting tools and weapons, while basalt and sandstone were used for ground stone tools, such as quern-stones. Wood, bone, shell, antler(deer) and other materials were widely used, as well. During the most recent part of the period, sediments (like clay) were used to make pottery. A series of metal technology innovations characterize the later Chalcolithic (Copper Age), Bronze Age and Iron Age.

The period from 2.62.58 Ma encompasses the first use of stone tools in Gona, Ethiopia and its spread and widespread use elsewhere soon thereafter. It ends with the development of agriculture, the domestication of certain animals, and the smelting of copper ore to produce metal. It is termed prehistoric since humanity had not yet started writing—the traditional start of history. (click to see all the article on Wikipedia)

石器時代 ~26十萬年前

石器時代指的是人類廣泛地使用石頭製作工具的史前時期。

石器使用各種不同的石頭來製作。例如,燧石與角岩被切削(或打製)成切割工具或武器,玄武岩及砂岩製作成研磨用石器,如手搖石磨。木材,骨材,貝殼,鹿角(鹿)以及其他材料也廣泛地被使用。在石器時代的後期,沈積物(如黏土)被用來製作陶器。一系列的冶金技術改革,被用來描繪後來的銅石並用時代(紅銅時代),青銅時代,鐵器時代。

約在26十萬到258萬年前首次使用石器,在包含哥納,埃賽俄比亞,以及其附近等地,不久之後廣泛地推廣到其他地區。之後隨著農業,馴養動物,冶煉銅礦的技術提昇,結束了石器時代。這時期被稱作史前時代,因為當時尚未開始書寫-傳統上歷史的開端。
