Prehistory
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.[3] Human population geneticists and historical linguists are also providing valuable insight for these questions.[4] 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.[4] Therefore, data about prehistory is provided by a wide variety of natural and social sciences, such as paleontology, biology, archaeology, palynology, geology, archaeoastronomy, comparative linguistics, anthropology, molecular genetics and many others.
