Traditional gradualist, evolutionary models of maize introduction in the American Bottom are re-examined.Excavations at hundreds of sites, analysis of thousands of liters of archaeobotanical samples, extensive AMS re-dating of archaeological and archaeobotanical samples, the isotopic studies of carbon and nitrogen isotopes for both human and dog populations, and a better understanding of the regional social and political sequence have caused ISAS researchers to doubt this evolutionary model. It now appears that Cahokia’s A.D. 1050 Big Bang with its changing political and social lifeways is fueled by the A.D. 900 introduction and dependence on new maize agriculture subsistence practices.
