The Qadan culture (13,000-9,000 BC) was a Mesolithic industry that, archaeological evidence suggests, originated in Upper Egypt (present day south Egypt) approximately 15,000 years ago [12][13] The Qadan subsistence mode is estimated to have persisted for approximately 4,000 years. It was characterized by hunting, as well as a unique approach to food gathering that incorporated the preparation and consumption of wild grasses and grains.[12][13] Systematic efforts were made by the Qadan people to water, care for, and harvest local plant life, but grains were not planted in ordered rows.[14]
