According to French botanist Agathe Roucou and colleagues, the domestication process also caused multiple changes in the plant that were generated indirectly. Plant Cell Environment 33:670685. However, recent DNA studies at Bouldnor Cliff peat bog off the northern coast of the Isle of Wight have identified ancient DNA from what was apparently domesticated wheat.

Modern wheat cultivars also have a shallower root system, with a larger proportion of fine roots, investing biomass above rather than below ground. About 10,000 years ago, T. aestivumderived from a cross between domesticated emmer (Triticum dicoccum) and the goat grass Aegilops tauschii.

One of the ongoing debates about wheat is the length of time it takes for the domestication process to complete. 8,000-7,000 The bones of humans who regularly ate corn during their lifetime have a high 13C measurement. Studies of bone size, bone strength, and osteoarthritis showed that in coastal areas, the adoption of farming is associated with a decrease in workload.

Wheat and barley are two of the founder crops of the agricultural revolution that took place 10,000 years ago in the Fertile Crescent and both crops remain among the world's most important crops. The domestication of wheat (Triticum aestivum L.) from wild grasses in the Middle East is a fascinating story that resulted in one of the worlds most important and widespread crops.
