It is in knowing what made past cultures cease to exist that could provide the key in making sure that history does not repeat itself.

Anthropologists can describe a people’s physical character, culture, and environmental and social relations.

Archaeologists, on the other hand, provide proof of authenticity of a certain artifact or debunk historical or anthropological findings.

Shell may succumb to isotopic exchange if it interacts with carbon from percolating ground acids or recrystallization when shell aragonite transforms to calcite and involves the exchange of modern calcite.

The surrounding environment can also influence radiocarbon ages.

History, anthropology, and archaeology are three distinct but closely related bodies of knowledge that tell man of his present by virtue of his past.

Historians can tell what cultures thrived in different regions and when they disintegrated.

Alone, or in concert, these factors can lead to inaccuracies and misinterpretations by archaeologists without proper investigation of the potential problems associated with sampling and dating.

To help resolve these issues, radiocarbon laboratories have conducted inter-laboratory comparison exercises (see for example, the August 2003 special issue of Radiocarbon), devised rigorous pretreatment procedures to remove any carbon-containing compounds unrelated to the actual sample being dated, and developed calibration methods for terrestrial and marine carbon. Radiocarbon dating can be used on either organic or inorganic carbonate materials.

The unstable and radioactive carbon 14, called radiocarbon, is a naturally occurring isotope of the element carbon.
