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.
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).
