On the origin and domestication of Olea europaea L. (olive) in Andalucía, Spain, based on the biogeographical distribution of its finds

Abstract

The remains of Olea europaea in archaeological contexts in the southern Iberian Peninsula have been found in the Epipalaeolithic levels of Cueva de Nerja (10860±160 b.p.). The abundant appearance of charcoal and some seed remains from the Copper Age (3rd millennium b.c.) in the coastal zones of the southeast indicate that this species formed part of the vegetation of the Thermo-mediterranean zone and that its fruits were collected during these periods. However, Olea did not appear in the Meso-mediterranean zone until the Roman period, when olive cultivation was introduced there. The presence of charcoal and olive stones from the 1st century a.d. onwards is abundant, together with remains of structures for oil pressing.
