These remains include the fossils (preserved bones) of humans, food remains, the ruins of buildings, and human artifactsitems such as tools, pottery, and jewelry.

Other sites that represent great human achievement are as varied as the cliff dwellings of the ancient Anasazi (a group of early Native Americans) at Mesa Verde, Colorado (see Mesa Verde National Park); the Inca city of Machu Picchu high in the Andes Mountains of Peru; and the mysterious, massive stone portrait heads of remote Easter Island in the Pacific.

Many of the objects left behind by past human societies are not present in the archaeological record because they have disintegrated over time.

The material remains that still exist after hundreds, thousands, or millions of years have survived because of favorable preservation conditions in the soil or atmosphere.

On rare occasions, however, delicate objects have been preserved.

For example, fabrics and flowers were found in the celebrated tomb of Tutankhamun, an Egyptian pharaoh who was buried in 1323 BC.

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.Today, archaeologists study the great cultural diversity of humanity in every corner of the world.Archaeological study covers an extremely long span of time and a great variety of subjects.Archaeological research spans the entire development of phenomena that are unique to humans.For instance, archaeology tells the story of when people learned to bury their dead and developed beliefs in an afterlife.Archaeologists have also recorded how primitive forms of humans spread out of Africa into Asia about 1.8 million years ago, then into Europe about 900,000 years ago.
