Harvesting by sickle yields straw as well as grain. Today we consider straw a by-product of cereal-farming, the primary purpose being to produce food. But archaeological evidence suggests things started the other way round.32 Human populations in the Middle East began settling in permanent villages long before cereals became a major component of their diets.33 In doing so, they found new uses for the stalks of wild grasses; these included fuel for lighting fires, and the temper that transformed mud and clay from so much friable matter into a vital tectonic resource, used to build houses, ovens, storage bins and other fixed structures. Straw could also be used to make baskets, clothing, matting and thatch.
process of plant domestication in the Fertile Crescent was not fully completed until much later: as much as 3,000 years after the cultivation of wild cereals
