Listeros,
Corn may have been an important part of the South American diet for
longer than previously thought according to research at the University
of Calgary. A new technique for examining ancient cooking pots has
produced the earliest directly dated examples of domesticated corn in
South American. Corn had become a vital crop in tropical Ecuador 5000
years ago. Microscopic starch grains survived in tropical climes and
can be used to identify exact species of plants and the researchers
analyzed charred food residues from ancient cooking pots in Ecuador.
