Archeology is the science that studies human cultures through the recovery, documentation, analysis and interpretation of material remains and environmental data, including architecture, artifacts, features, biofacts, and landscapes.
The goals of archeology vary, and there is debate as to what its aims, and responsibilities are. Some goals include the documentation and explanation of the origins and development of human cultures, understanding culture history, chronicling cultural evolution, and studying human behavior and ecology, for both prehistoric and historic societies.
Archaeologists are also concerned with the study of methods used in the discipline, and the theoretical and philosophical underpinnings underlying the questions archaeologists ask of the past. The tasks of surveying areas in order to find new sites, excavating sites in order to recover cultural remains, classification, analysis, and preservation are all important phases of the archaeological process. These are all important sources of information. Given the broad scope of the discipline there is a great deal of cross-disciplinary research in archeology.
