Archeology is the scientific study of past human culture and behavior, from the origins of humans to the present.Archaeology studies past human behavior through the examination of material remains of previous human societies.
Archaeologists concentrate their studies on past societies and changes in those societies over extremely long periods of time.
For the most part, the only things that survive are durable items such as potsherds (small fragments of pottery), tools or buildings of stone, bones, and teeth (which survive because they are covered with hard enamel).
Because many items disintegrate over time, archaeologists get an incomplete view of the past that they must fill in with other kinds of information and educated reasoning.
Archaeology became established as a formal discipline in the 19th and early 20th centuries.
At that time, most archaeological work was confined to Europe, to the so-called cradle of civilization in southwestern Asia, and to a few areas of the Americas.
