Early hominid fossil remains and carbon 14 dating
The earliest archaeological sites include those at Hadar, Ethiopia; Olduvai Gorge and Laetoli, Tanzania; East Turkana, Kenya; and elsewhere in East Africa.
These sites contain evidence of the first appearance of bipedal (upright walking), apelike early humans.
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.
Archaeology also examines many of the same topics explored by historians.
But unlike historythe study of written records such as government archives, personal correspondence, and business documentsmost of the information gathered in archaeology comes from the study of objects lying on or under the ground Archaeologists refer to the vast store of information about the human past as the archaeological record.
Laetoli even reveals footprints of humans from 3.6 million years ago.
