This dissertation focuses on plant food production, human adaptation, and cultural interaction in the highlands of Ecuador during the Formative Period. I conducted starch granule analysis of ceramic charred cooking and stone tool residues from some of the earliest Formative Period sites in the highlands, and one site from the eastern Andean slopes, to develop a regional synthesis of the timing and nature of highland plant food production. The main hypothesis tested is whether the stimulus to a Formative lifeway in the highlands diffused from coastal Ecuador. Sites investigated include La Chimba, Tajamar, Cerro Narrío, Chaullabamba, La Vega, Trapichillo, and Santa Ana-La Florida (SALF). I also integrate data from previous botanical analyses at other sites, especially Cotocollao.
The analyses show that Andean domesticated crops, such as oca, potato, lupines (chocho/tarwi) and quinoa, as well as maize and beans, are associated with the highland sites located at, and to the north of, Chaullabamba (La Chimba, Tajamar, and Cerro Narrío). By employing site catchment analysis, I contend that a highland, “vertical compact”, agricultural system was being practiced at these sites by at least the terminal Early Formative period, and perhaps much earlier based on proxy (pollen) evidence and aspects of the plants’ nutritional profiles, which suggest long-standing familiarity with the crops. By integrating the latest information available on the crops’ origins, I argue that cultural interaction was perhaps principally occurring through the Inter-Andean corridor along a north-south axis with other highland groups.
