"Ten thousand years ago, corn didn't exist anywhere in the world, and until recently scientists argued vehemently about its origins. Today the crop is consumed voraciously by us, by our livestock, and as a major part of processed foods. Popped Secret: The Mysterious Origin of Corn tells the story of the genetic changes that produced corn from what may seem like an unlikely ancestor: a wild grass called teosinte. See how evidence from genetics and archeology pinpoint corn's origins to a very particular time and place in Mexico."--Container.
