A new study published in Science has introduced a refined dating technique using Chlorine-36 surface exposure pulses to date the construction of stone granaries in the Jordan Valley. This methodology allows for a seasonal resolution that traditional Carbon-14 dating cannot achieve, pushing the timeline of the first organized agricultural storage back by nearly 400 years.
The data reveals that the transition to permanent sedentism was catalyzed by a specific 50-year period of climatic stability. By applying this 'Chlorine-36' calibration, researchers were able to map the exact sequence of building phases in Neolithic villages, providing a new benchmark for understanding the socio-economic shifts that defined the dawn of civilization in the Levant.
