This article from the Jerusalem Post discusses the findings of some new research on the domestication of various grains in the Ancient Near East, Europe, and the Americas. Not only does it show that domestication of a particular crop might be started in one location (Turkey), and later (thousands of years) completed in a distant location (Central Europe), but that the process began much earlier than previously imagined. Two examples include fig cultivation in the Jordan Valley 10,000 years ago and 100,000+ finds of wild oats and barley near Jericho from 11,000 years ago.
