Where does wheat come from?
Wild wheat is native to Eurasia and is one of the first plant species domesticated by humans. It was first domesticated between 8,000 and 12,000 years ago, in the ancient Near East. The consistent nutrition it provided contributed to the rise of city-states in the Fertile Crescent area, some of the first civilizations. Since the ancient Near East was hot and had excellent soil, wheat was ideal because it is very adaptable, growing under temperature conditions ranging from 36 to 90 degrees Fahrenheit. The Great Plains of North America have proven particularly hospitable to wheat and produce the vast majority of American wheat on the market. Source: archaeology.about.com
