‘So why did agriculture happen? […]
Historians don’t know for sure, of course, because there are no written records. But, they love to make guesses. Maybe population pressure necessitated agriculture even though it was more work, or abundance gave people leisure to experiment with domestication, or planting originated as a fertility rite – or as some historians have argued – people needed to domesticate grains in order to produce more alcohol.
Charles Darwin, like most 19th century scientists, believed agriculture was an accident, saying, “a wild and unusually good variety of native plant might attract the attention of some wise old savage.”‘
