“…Olive cultivation, based on the domesticated form, is considered to have begun during the Chalcolithic cultural period (also termed Copper Age), when the development of techniques for oil extraction and the presence of olives is recorded at several sites in the Jordan Valley, in the Golan Heights, and in the rest of the Levant (Abu Hamid, el‐Khawarij, Rasm Harbush, Samaria, Teleilat Ghassul, Tel Saf, Tell esh‐Shuna) (Gophna & Kislev, 1979; Neef, 1990; Liphschitz et al , 1991; Epstein, 1993; Carmi & Segal, 1998; Zohary & Hopf, 2000). Radiocarbon dating data from Teleilat Ghassul and el‐Khawarij, Jordan Valley, give a maximum age of 5510 ± 40 14 C BP (2 σ range: 6400‐6270 BP) for olive pits, and 5370 ± 70 14 C BP (2 σ range: 6300‐6000 BP) for oil extraction, indicating a possible Chalcolithic emergence of olive cultivation (Bourke et al , 2004; Lovell et al , 2010). However, Chalcolithic extractions of oil may still result from oleasters (Salavert, 2008), pushing the origin of the domesticated form to the Early Bronze Age (5300‐4100 BP), when olive remains became more abundant at sites such as Tel Yarmouth, Tel Erani, Tel Qashish and Tel Taanach (Liphschitz et al , 1991; Salavert, 2008).…”
