谷物农业起源于新月沃地对大麦和早期小麦的驯化。长期以来，人们一直猜测大麦不止一次被驯化。我们利用多个位点的地理区域之间的单倍型频率差异来推断大麦至少有两个驯化;一个在新月沃土内，另一个在更远的东部1500 - 3000公里处。新月沃土驯化贡献了欧洲和美国栽培品种的大部分多样性，而第二驯化贡献了从中亚到远东的大麦的大部分多样性。
Cereal agriculture originated with the domestication of barley and early forms of wheat in the Fertile Crescent. There has long been speculation that barley was domesticated more than once. We use differences in haplotype frequency among geographic regions at multiple loci to infer at least two domestications of barley; one within the Fertile Crescent and a second 1,500-3,000 km farther east. The Fertile Crescent domestication contributed the majority of diversity in European and American cultivars, whereas the second domestication contributed most of the diversity in barley from Central Asia to the Far East.
