Archaeology is the study of the past using material remains. It is complementary to history as it provides information about prehistory, which accounts for 99.9% of human history. Archaeology crosses disciplinary boundaries and takes a holistic approach, recognizing that the past is intertwined. It informs our understanding of heritage value and the importance of heritage education. The document outlines key concepts in archaeology like sites, monuments, artifacts, and formation processes, and traces the evolution of archaeological theory from antiquarianism to newer processual and post-processual approaches.
