Dates have been a staple food of the Middle East and the Indus Valley for thousands of years. There is archaeological evidence of date cultivation in eastern Arabia between 5530 and 5320 calBC. They are believed to have originated around what is now Iraq, and have been cultivated since ancient times from Mesopotamia to prehistoric Egypt. The Ancient Egyptians used the fruits to make date wine, and ate them at harvest.
There is also archeological evidence of date cultivation in Mehrgarh around 7000 BCE, a Neolithic civilization in what is now western Pakistan. Evidence of cultivation is continually found throughout later civilizations in the Indus Valley, including the Harappan period 2600 to 1900 BCE.
In later times, traders spread dates around South West Asia, northern Africa, and Spain. Dates were introduced into Mexico and California by the Spaniards in 1765, around Mission San Ignacio.
A date palm cultivar, probably what used to be called Judean date palm, is renowned for its long-lived orthodox seed, which successfully sprouted after accidental storage for 2000 years. The upper survival time limit of properly stored seeds remains unknown.
Fossil records show that the date palm has existed for at least 50 million years.
