Archaeology is an important field of anthropology, which is the broad study of human culture and biology.
Archaeologists concentrate their studies on past societies and changes in those societies over extremely long periods of time.
The earliest archaeological sites include those at Hadar, Ethiopia; Olduvai Gorge and Laetoli, Tanzania; East Turkana, Kenya; and elsewhere in East Africa.
From their studies, archaeologists attempt to reconstruct past ways of life.
The earliest subjects of archaeological study date from the origins of humanity.
These include fossil remains believed to be of human ancestors who lived 3.5 million to 4.5 million years ago.
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.
