Today, archaeologists study the great cultural diversity of humanity in every corner of the world.
These include fossil remains believed to be of human ancestors who lived 3.5 million to 4.5 million years ago.
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.
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.Dozens of archaeological sites throughout Asia and Europe show how people migrated from Africa and settled these two continents during the last Ice Age (100,000 to 15,000 years ago).Archaeological studies have also provided much information about the people who first arrived in the Americas over 12,000 years ago.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.Sites containing signs of the first simple but purposeful burials in graves date to as early as 40,000 years ago in Europe and Southwest Asia.
