South American archaeology surveys the prehistoric and historic human past across the South American continent through excavation, survey, and analysis of material remains. It synthesizes data from sites such as Monte Verde, Caral, Machu Picchu, Tiwanaku, and Chan Chan to reconstruct migrations, social complexity, and environmental interaction. Major institutions including the Smithsonian Institution, British Museum, Museo Larco, Museo Nacional de Antropología (Peru), and universities such as Universidad de San Marcos, Pontifical Catholic University of Peru, Universidad Nacional Mayor de San Marcos, University of Cambridge, and Harvard University have been central to research and curation.

Prehistoric human settlement and migration

Early settlement debates center on sites like Monte Verde, Pedra Furada, Nanchoc, Santa Elena Peninsula, and Piedra Museo that inform models of peopling via coastal and inland routes. Genetic studies from teams at Max Planck Society, University of Oxford, University of California, Berkeley, and University of São Paulo use ancient DNA from remains associated with Lagoa Santa, Chiribaya, Toconao, and Arenosa to test hypotheses of migration waves linked to populations related to Beringia, Anzick-1, and later gene flow involving contacts with Polynesia suggested by analyses involving Easter Island and Rapa Nui. Radiocarbon chronologies calibrated by laboratories at University of Groningen, University of Arizona, and University of Oxford refine timelines for preceramic occupations at Guitarrero Cave, Los Toldos, Cueva Fell, and Paleoindian horizons.

Major cultural periods and regional chronologies

Archaeologists organize time into sequences such as Preceramic/Formative exemplified by Norte Chico, Caral-Supe, and Cupisnique; Early Horizon associated with Chavín de Huántar and the spread of Chavín iconography; Middle Horizon reflecting the expansion of Tiwanaku and Wari polities; Late Intermediate marked by regional states like Chimú and Moche; and Late Horizon dominated by the Inca Empire. Regional chronologies in the Andes, Amazon Basin, Gran Chaco, Patagonia, Pampean and Coastal Peru integrate ceramic sequences from sites like Huaca Prieta, Kotosh, El Paraíso, and Pukara alongside architectural phases at Chan Chan and Machu Picchu.

Key civilizations and archaeological sites

Major civilizations include the coastal urban complex of Norte Chico with centers like Caral; the highland ceremonial state of Chavín centered at Chavín de Huántar; the coastal kingdoms of Moche with tombs at Sipán and huacas like Huaca del Sol; the iconographically rich Nazca with the Nazca Lines; the imperial capitals of Tiwanaku on the southern Titicaca basin and Cusco for the Inca Empire; and the adobe metropolis of Chan Chan for Chimú. Other key sites include Kuelap, Pachacamac, Pukara de Quitor, Sechín Bajo, Guitarrero Cave, Cerro Sechín, Samanco, and Huánuco Pampa.

Material culture and technological developments

Artifacts reflect metallurgy, ceramics, textiles, and architectural innovation. Metallurgical traditions at Moche and Inca sites show gold and copper alloying techniques studied in labs at Massachusetts Institute of Technology and University of Chicago. Ceramics typologies from Nazca polychrome, Moche stirrup-spout, and Wari fine-line styles are central to chronology and trade reconstructions. Textile production in highland centers like Cusco and sites studied by curators at Museo Textile Regional demonstrates warp-faced weaving, camelid fiber processing, and iconography paralleled in collections at Metropolitan Museum of Art. Architectural systems include monumental stone masonry at Sacsayhuamán, adobe urbanism at Chan Chan, irrigation infrastructure associated with Nazca and Moche valleys, and terrace agriculture visible at Moray.

Subsistence, environment, and landscape archaeology

Domesticates—maize, potato, quinoa, manioc, cassava, and camelids—are traced through paleoethnobotanical assemblages from Huaca Prieta, Guitarrero Cave, Cerro Llullaillaco, and Acarapi. Zooarchaeological records from Nazca, Moche, Tiwanaku, and Inca contexts reveal camelid herding, guanaco hunting, and marine exploitation at Pisco Bay and Bahía de Paracas. Paleoenvironmental reconstructions using sediment cores from Lake Titicaca, Lago General Carrera, and Laguna de Maracaibo and palynology conducted at Smithsonian Tropical Research Institute and Instituto de Investigaciones de la Amazonía Peruana document Holocene climate variability, Andean glacial fluctuation, and human-driven landscape modification including terracing, raised fields at Suka Kollus, and irrigation canals in the Moche Valley.

Research history, methods, and theoretical approaches

Research history spans 19th-century explorers like Alexander von Humboldt and Joaquín de Egaña to 20th-century figures such as Max Uhle, Hiram Bingham, Julio C. Tello, and Ruth Shady. Methodological advances include stratigraphic excavation practices developed at Harvard University and University of Cambridge, radiocarbon dating popularized through collaborations with University of California, Irvine, dendrochronology at University of Arizona, and aDNA analyses at Max Planck Society. Theoretical approaches range from culture-historical frameworks advanced by Paul Rivet and Willey to processual and post-processual debates involving scholars at University of Oxford, Stanford University, University of Chicago, and indigenous community collaborations with organizations like CONDESAN and Ministerio de Cultura (Peru). Contemporary priorities emphasize heritage management, repatriation dialogues with museums such as the British Museum and Museo Nacional de Antropología (Madrid), community archaeology at Kichwa and Aymara communities, and interdisciplinary projects integrating remote sensing from NASA, LiDAR surveys led by teams from University of Vermont and Carnegie Institution for Science, and stable isotope studies at University of Grenoble Alpes.
