This interactive timeline marking major events in the history and evolution of food, crops, migration of food, agriculture and cooking methods were created in 2012 by myself (Lena Struwe) and my students in a freshman Byrne Seminar at Rutgers University.  We used software called TimeGlider to build it and it is unfortunately no longer available. But the timeline is still available to explore online.  The items on the timeline were selected by students so there is a certain randomness to them, but all kinds of cool facts and trends can be seen.  Take a look, and feel free to send your students the link for learning more about the Evolution of Food, Crops, and Cooking (which was also the name of the class).
