Bread and durum wheat are both domesticated forms of wild emmer wheat. It was formed from hybridization of domesticated tetraploid wheat [T. turgidum L. ssp. Today, it grows along the Near Eastern Fertile Crescent in countries such as Israel, Jordan, Syria, Lebanon, eastern Turkey, western Iran, and northern Iraq.

Domestication has genetically not only transformed the brittle rachis, tenacious glume and non-free threshability, but also modified yield and yield components in wheat. When wild wheat ripens, the stems, the part that holds the wheat stems together, break down so that the seeds can self-pollinate and sprout faster without the husk. John Murray, London (popular edition in two volumes) 566 p, Doebley J (1989) Isozymic evidence and the evolution of crop plants.

Of these traits, grain retention and threshability, yield improvement, changes to photoperiod sensitivity and nutritional value are most pronounced between wild and domesticated forms. The domestication of wheat around 10,000 years ago marked a dramatic turn in the development and evolution of human civilization, as it enabled the transition from a hunter-gatherer and nomadic pastoral society to a more sedentary agrarian one. This change was possible because of a random mutation in the wild populations at the beginning of wheat's cultivation.

According to French botanist Agathe Roucou and colleagues, the domestication process also caused multiple changes in the plant that were generated indirectly. Wheat is a grain product with about 25,000 different varieties today.
