ve (botanical name Olea europaea, "European olive") is a species of subtropical evergreen tree in the family Oleaceae. Originating in Asia Minor,[2] it is abundant throughout the Mediterranean Basin, with wild subspecies in Africa and western Asia; modern cultivars are traced primarily to the Near East, Aegean Sea, and Strait of Gibraltar.[3] The olive is the type species for its genus, Olea, and lends its name to the Oleaceae plant family, which includes lilac, jasmine, forsythia, and ash. The olive fruit is classed botanically as a drupe, similar in structure and function to the cherry or peach. The term oil was originally synonymous with olive oil, the liquid fat derived from olives.The olive has deep historical, economic, and cultural significance in the Mediterranean.[4][5][6] It is among the oldest fruit trees domesticated by humans,[7] being first cultivated in the Eastern Mediterranean between 6,000 and 4,000 BC, most likely in the Levant.[3] The olive gradually disseminated throughout the Mediterranean via trade and human migration starting in the 16th century BC;[8] it took root in Crete around 3500 BC and reached Iberia by about 1050 BC. Olive cultivation was vital to the growth and prosperity of various Mediterranean civilisations, from the Minoans and Myceneans of the Bronze Age to the Greeks and Romans of classical antiquity.[9][10]
