“…Since the early discoveries, sites identified as Natufian have been reported both from the core area (12,49,65,67,78,88) and from regions further away, some within different phytogeographic zones: northem Syria (26,27,60), north and south Lebanon (19), the Jordan Rift Valley (9,33,38), southem Jordan (46,55,56), the Syrian-Arabian Desert (20), and the Negev (43,58,61) (Figure 1).
