Archaeology emerged as part of the general discipline of anthropology in North America, the overall focus of which for the first five or six decades of the twentieth century was to write the history of the culture of each group of native North American people. The goal of writing a culture’s history could only be accomplished by placing artifacts in a chronological sequence, which demanded a chronometer. It was not always possible to refer to stratigraphic superposition, so various techniques of seriation—arranging artifacts based on their formal attributes in what was believed to be a chronological order—were invented and used. The results of the seriation techniques and stratigraphic superposition studies were initially summarized in tables of artifact frequencies but eventually were graphed in several ways. Interest in culture chronology and change among North American archaeologists has extended throughout the twentieth century and into the twenty-first century.
