A report led by two northern Illinois anthropologists sheds new light on a South American civilization’s origins…and its dependence on corn.
WNIJ’s Susan Stephens spoke with Northern Illinois University professor Winifred Creamer about her work at a five-thousand year-old archeological site in Peru and how it has changed one long-held theory about the people who lived there. Creamer's co-researchers in this study include Jonathan Haas of the Field Museum in Chicago.
