Until now, researchers believed farming was "invented" some 12,000 years ago in the Cradle of Civilization -- Iraq, the Levant, parts of Turkey and Iran -- an area that was home to some of the earliest known human civilizations. A new discovery by an international collaboration of researchers from Tel Aviv University, Harvard University, Bar-Ilan University, and the University of Haifa offers the first evidence that trial plant cultivation began far earlier -- some 23,000 years ago.
