In the dry foothills of Iran's Zagros Mountains, a new picture of mankind's first farmers is emerging from an archaeological dig that has turned up a jackpot of artifacts and plant grains.
People who lived in the region began cultivating cereal grains as early as 11,700 years ago, according to the new analysis, which adds Iran to the list of places in the Near East where the first inklings of farming emerged just after the end of the last Ice Age.
Once people figured out how to cultivate, and then domesticate, plants and animals, they eventually developed settlements and agricultural economies that formed the foundation of modern civilizations, said Nicholas Conrad, head of the archaeological team that made the new discoveries.
Along with previous work in nearby regions, the new study suggests that farming began simultaneously over a widespread area, offering an important window into a pivotal time in human history.
"There is not just one village where you can say, ‘This is where domestication occurred,'" said Conrad, of the University of Tübingen in Germany. "It wasn't as if the development of agriculture was like someone flipped a light in one place and from that point of origin, agriculture spread. It's a process that occurred in a whole range of places."
