Peas are a cool-season crop grown in many parts of the world.
Wild relatives of pea include the species P. fulvum and the subspecies P. sativum subsp. elatius. Wild peas are characterized by spontaneous dehiscence of pods and ballistic seed spread.
The wild pea is restricted to the Mediterranean basin and the Near East. The earliest archaeological finds of peas date from the late neolithic era of current Greece, Syria, Turkey and Jordan. In Egypt, early finds date from c. 4800–4400 BC in the Nile delta area, and from c. 3800–3600 BC in Upper Egypt. The pea was also present in Georgia in the 5th millennium BC. Farther east, the finds are younger. Peas were present in Afghanistan c. 2000 BC, in Harappa, Pakistan, and in northwest India in 2250–1750 BC. In the second half of the 2nd millennium BC, this peas appear in the Ganges Basin and southern India.
