Stone Age, prehistoric cultural stage, or level of human development, characterized by the creation and use of stone tools. The Stone Age, whose origin coincides with the discovery of the oldest known stone tools, which have been dated to some 3.3 million years ago, is usually divided into three separate periods—Paleolithic Period, Mesolithic Period, and Neolithic Period—based on the degree of sophistication in the fashioning and use of tools.Paleolithic archaeology is concerned with the origins and development of early human culture between the first appearance of human beings as tool-using mammals (which is believed to have occurred sometime before 3.3 million years ago) and about 8000 BCE (near the beginning of the Holocene Epoch [11,700 years ago to the present]). It is included in the time span of the Pleistocene, or Glacial, Epoch—an interval lasting from about 2,600,000 to 11,700 years ago. Modern evidence suggests that the earliest protohuman forms had diverged from the ancestral primate stock by the beginning of the Pleistocene. In any case, the oldest recognizable tools were found in rock layers of Middle Pliocene Epoch (some 3.3 million years ago), raising the possibility that toolmaking began with Australopithecus or its contemporaries. During the Pleistocene, which followed directly after the Pliocene, a series of momentous climatic events occurred. The northern latitudes and mountainous areas were subjected on four successive occasions to the advances and retreats of ice sheets (known as Günz, Mindel, Riss, and Würm in the Alps), river valleys and terraces were formed, the present coastlines were established, and great changes were induced in the fauna and flora of the globe. In large measure, the development of culture during Paleolithic times seems to have been profoundly influenced by the environmental factors that characterize the successive stages of the Pleistocene Epoch. Throughout the Paleolithic, humans were food gatherers, depending for their subsistence on hunting wild animals and birds, fishing, and collecting wild fruits, nuts, and berries. The artifactual record of this exceedingly long interval is very incomplete; it can be studied from such imperishable objects of now-extinct cultures as were made of flint, stone, bone, and antler. These alone have withstood the ravages of time, and, together with the remains of contemporary animals hunted by our prehistoric forerunners, they are all that scholars have to guide them in attempting to reconstruct human activity throughout this vast interval—approximately 98 percent of the time span since the appearance of the first true hominin stock. In general, these materials develop gradually from single, all-purpose tools to an assemblage of varied and highly specialized types of artifacts, each designed to serve in connection with a specific function. Indeed, it is a process of increasingly more complex technologies, each founded on a specific tradition, that characterizes the cultural development of Paleolithic times. In other words, the trend was from simple to complex, from a stage of non specialization to stages of relatively high degrees of specialization, just as has been the case during historic times.
