Answer:
three periods
Divided into three periods: Paleolithic (or Old Stone Age), Mesolithic (or Middle Stone Age), and Neolithic (or New Stone Age), this era is marked by the use of tools by our early human ancestors (who evolved around 300,000 B.C.) and the eventual transformation from a culture of hunting and gathering to farming
Explanation:
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.
A constitution is an aggregate of fundamental principles or established precedents that constitute the legal basis of a polity, organisation or other type of entity and commonly determine how that entity is to be governed.
