Bitter vetch ("V. ervilia") was one of the first domesticated crops. It was grown in the Near East about 9,500 years ago, starting perhaps even one or two millennia earlier during the Pre-Pottery Neolithic A. By the time of the Central European Linear Pottery culture – about 7,000 years ago – broad bean ("V. faba") had also been domesticated. Vetch has been found at Neolithic and Eneolithic sites in Bulgaria, Hungary and Slovakia. And at the same time, at the opposite end of Eurasia, the Hoabinhian people also utilized the broad bean in their path towards agriculture, as shown by the seeds found in Spirit Cave, Thailand.
