From about 2.5 million years ago until 14,000 BC, the dominant material used to make tools and other artifacts was stone. This period is commonly referred to as the Stone Age, and it is divided into three distinct periods: the Paleolithic, the Mesolithic, and the Neolithic. During this time, humans learned to craft stone tools using a variety of techniques, including flaking, grinding, and polishing. These tools were used for a variety of purposes, including hunting, food processing, and building shelter. While bone and plant remains were also used to make artifacts, stone was by far the most prevalent material. Ceramic and metal artifacts did not appear until much later in human history.
