We don’t know whether sloth (not wanting to walk from stand to stand), greed (just wanting more food), or fear (of hunger or of someone else getting to the plant first) was the inspiration, but someone, very likely a woman, had a bright idea: Why not take some of the best seeds and replant them in a particularly fertile spot? Then, she presumably thought, if we look after them—turning the soil, pulling up weeds, maybe even watering the plants—we can rely on them to be there every year, and even to give us better yields. Life is good.
