Civilization or civilisation (in British English) generally refers to state polities which combine these basic institutions, having one or more of each: a ceremonial centre (a formal gathering place for social and cultural activities), a system of writing, and a city. The term is used to contrast with other types of communities including hunter-gatherers, nomadic pastoralists and tribal villages. Civilizations have more densely populated settlements divided into hierarchical social classes with a ruling elite and subordinate urban and rural populations, which, by the division of labour, engage in intensive agriculture, mining, small-scale manufacture and trade. Civilization concentrates power, extending human control over both nature, and over other human beings.[1]The emergence of civilization is generally associated with the final stages of the Neolithic Revolution, a slow cumulative process occurring independently over many locations between 10,000 and 3,000 BCE, culminating in the relatively rapid process of state formation, a political development associated with the appearance of a governing elite. This neolithic technology and lifestyle was established first in the Middle East (for example at Göbekli Tepe, from about 9,130 BCE), and Yangtze and later in the Yellow river basin in China (for example the Pengtoushan culture from 7,500 BCE), and later spread. But similar "revolutions" also began independently from 9,000 years ago in such places as the Norte Chico civilization in Peru[2] and Mesoamerica at the Balsas River. These were among the six civilizations worldwide that arose independently.[3] This revolution consisted in the development of the domestication of plants and animals and the development of new sedentary lifestyles which allowed economies of scale and productive surpluses.
