Abstract
The 13C/12C ratio in human collagen was determined for 19 individuals from Hopewell sites in Wisconsin, Illinois, and Ohio and compared with 27 new measurements from individuals of Archaic, Mississippian, and Late Woodland affiliation. Additional measurements were made of elements in the food chain and on experimental animals fed on a diet of known composition containing maize. The similarity of the Hopewell measurements to those of nonmaize diets indicates that corn was of little importance in the Hopewell diet for those populations tested.
