Wheat domestication involves a limited number of chromosome regions, or domestication syndrome factors, though many relevant quantitative trait loci have been detected. The effect of domestication on awns in wheat does not match the clear differences between wild and domestic gene pools for other traits.

PubMed Wild emmer genome architecture and diversity elucidate wheat evolution and domestication. While there is evidence that the inclusion of wheat and wild grains has expanded peoples diets, some scientists say there is no evidence that these plants were deliberately planted. But other experiments led by evolutionary geneticist Robin Allaby and originally published in Watson (2018) suggest that ancient DNA from submarine sediments is less degraded than in other environments. Wheat was domesticated ten thousand years ago in the present-day Middle East, when humans rapidly modified the crop's key traits. Case Study: Wheat Domestication and Breeding. Modern wheat cultivars also have a shallower root system, with a larger proportion of fine roots, investing biomass above rather than below ground.

But additional experiments run by British evolutionary geneticist Robin Allaby and preliminarily reported in Watson (2018) have shown that ancient DNA from undersea sediments is more pristine than that from other contexts. According to genetic and archaeological studies, todays wheat originates from the Karacada mountain region in southeast Turkey.

Bread wheat is one of the most important crops in the world. The genetic changes during domestication mean that modern wheats are unable to survive wild in competition with better adapted species. Genes from Aegilops species and other wild relatives have been extremely important for improving a number of traits in wheat, especially disease resistance. CAS The Wheat Genetics Resource Center at Kansas State University has been a leader in collecting, conserving, and exploiting wild wheat relatives for crop improvement.

The earliest evidence for both domesticated einkorn and emmer wheat found to date was at the Syrian site of Abu Hureyra, in occupation layers dated to the Late Epi-paleolithic period, the beginning of the Younger Dryas, ca 13,00012,000 cal BP; some scholars have argued, however, that the evidence does not show deliberate cultivation at this time, although it does indicate a broadening of the diet base to include a reliance on wild grains including the wheat.
