POORPOLIO AGE:
Paleolithic period or Old Stone Age is the earliest period of human development and the longest phase of mankind's history. It is approximately coextensive with the Pleistocene geologic epoch, beginning about 2 million years ago and ending in various places between 40,000 and 10,000 years ago, when it was succeeded by the Mesolithic Period.
NOBOPOLIO AGE:
The Neolithic Age or New Stone Age was a period in the development of human technology, beginning about 9500 BC in the Middle East that is traditionally considered the last part of the Stone Age. The Neolithic followed the terminal Holocene Epipalaeolithic periods, beginning with the rise of farming, which produced the "Neolithic Revolution" and ending when metal tools became widespread in the Copper Age or Bronze Age or developing directly into the Iron Age, depending on geographical region. THE BRONZE AGE:
The bronze age is a period characterized by the use of copper and its alloy bronze and proto-writing, and other features of urban civilization. An ancient civilization can be in the Bronze Age either by smelting its own copper and alloying with tin, or by trading for bronze from production areas elsewhere.
THE IRON AGE:
The iron age is the period generally occurring after the Bronze Age, marked by the prevalent use of iron. The early period of the age is characterized by the widespread use of iron or steel. The adoption of such material coincided with other changes in society, including differing agricultural practices, religious beliefs and artistic styles. The beginning of the Iron Age in Europe and adjacent areas is characterized by certain forms of implements, weapons, personal ornaments, and pottery, and also by systems of decorative design, which are altogether different from those of the preceding age of bronze.
