  The main source of information for prehistory is archaeology (a branch of anthropology), but some scholars are beginning to make more use of evidence from the natural and social sciences.
  
  The primary researchers into human prehistory are archaeologists and physical anthropologists who use excavation, geologic and geographic surveys, and other scientific analysis to reveal and interpret the nature and behavior of pre-literate and non-literate peoples. Human population geneticists and historical linguists are also providing valuable insight. Cultural anthropologists help provide context for societal interactions, by which objects of human origin pass among people, allowing an analysis of any article that arises in a human prehistoric context. Therefore, data about prehistory is provided by a wide variety of natural and social sciences, such as anthropology, archaeology, archaeoastronomy, comparative linguistics, biology, geology, molecular genetics, paleontology, palynology, physical anthropology, and many others.
  
  Human prehistory differs from history not only in terms of its chronology, but in the way it deals with the activities of archaeological cultures rather than named nations or individuals. Restricted to material processes, remains, and artefacts rather than written records, prehistory is anonymous. Because of this, reference terms that prehistorians use, such as " Neanderthal " or " Iron Age ", are modern labels with definitions sometimes subject to debate.
