Paleolithic Period [Палеоліт; Paleolit]. The earliest period of human development, lasting until approx 8000 BC. In Western archeology the Paleolithic Period (or Old Stone Age) is divided into two epochs: the Lower Paleolithic (to 40,000 BC) and the Upper Paleolithic (40,000–8000 BC).
The Neolithic Revolution started around 10,000 B.C. in the Fertile Crescent, a boomerang-shaped region of the Middle East where humans first took up farming. Shortly after, Stone Age humans in other parts of the world also began to practice agriculture.
A civilization or civilisation (see English spelling differences) is any complex society characterized by urban development, social stratification imposed by a cultural elite, symbolic systems of communication (for example, writing systems), and a perceived separation from and domination over the natural environment
