The genetic changes during domestication mean that modern wheats are unable to survive wild in competition with better adapted species. The International Maize and Wheat Improvement Center (CIMMYT) has been a leader in producing and utilizing synthetic hexaploids, with over 1,500 synthetics developed (Mujeeb-Kazi and Hettel, 1995; Rosyara et al., 2019). Some scholars argue for a fairly rapid process, of a few centuries; while others argue that the process from cultivation to domestication took up to 5,000 years.

Modern wheat cultivars also have a shallower root system, with a larger proportion of fine roots, investing biomass above rather than below ground. Although the Fertile Crescent is renowned as the center of wheat domestication, archaeological studies have shown the crucial involvement of atalhyk in this process.

Dr. Patrick Byrne highlights examples of contrasting traits in modern wheat and its wild ancestors or heirloom varieties, providing insight into the history of wheat breeding. However, recent DNA studies at the Bouldnor Cliff peat bog off the north coast of the Isle of Wight have identified ancient DNA from domesticated wheat.
