The Stone Age is marked by the manufacture of stone tools, which differentiates human beings from other animals. This production began with the practice of hitting stones together to create sharp points. Around 700,000 years ago, Homo erectus learned to carve stones. This advance was only possible with the mastery of fire, which served to ward off animals, light up the camps at night and, mainly, for cooking. Cooked food was another decisive factor in increasing the human population and for the survival of human beings. The Stone Age can be divided into two parts: the Paleolithic, or Chipped Stone Age, and the Neolithic, or Polished Stone Age. The latter was marked by the beginning of a sedentary lifestyle, known as the Neolithic Revolution, which lasted approximately 10,000 years and brought agriculture and the domestication of animals.
