American archaeology is the study of past human societies in the United States and its territories. It involves examining artifacts, structures, and other physical remains to understand how people lived, interacted, and adapted to their environments. This field covers a wide range of cultures, from ancient Native American civilizations to more recent historical periods. Archaeologists use various methods, including excavation and analysis of materials, to uncover information about daily life, trade, and social organization. Important sites, such as Cahokia and Mesa Verde, provide valuable insights into the diverse histories of the Americas and contribute to our understanding of human development over time.
