One possible way that might have occurred is that farmers harvested wheat after it was ripe, but before it self-dispersed, thereby collecting only the wheat that was still attached to the plant.

The earliest known use of emmer was gathered from wild patches by the people who lived at the Ohalo II archaeological site in Israel, about 23,000 years ago. The domestication of wheat was instrumental in the transition of human behavior from hunter-gatherers to farmers. The sediments were laid down about 8,000 years ago, several centuries earlier than the European LBK sites. Expert Answer. It differs from wild wheat in that it has non-shattering spikes, an adaptation that allows the plant to better retain its seeds and to be harvested more easily. tauschii plants, creating a so-called bottleneck effect where only a limited amount of D-genome variation became incorporated into the hexaploid crop.

Formed partly by migratory farmers and partly by local hunter-gatherers adapting new technologies, the Lindearbandkeramik (LBK) culture is often associated with the importation of wheat and other crops from Asia to Europe. These chromosome sets are designated the A, B, and D genomes, each with seven pairs of chromosomes. 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 hybridization is believed to have occurred only 8000 to 10,000 years ago, most likely in an area south of the Caspian Sea in present-day Iran (Gepts, 2018).

Mol Biol Evol 19:17971801, PubMed The effect of domestication on awns in wheat does not match the clear differences between wild and domestic gene pools for other traits. The earliest present evidence for the utilization of wheat comes from the Ohalo II site in Israel, where the wild, brittle tetraploid wheat Triticum dicoccoides, dated as 19,000 years old, was found, suggesting the initial steps towards sedentism and cereal agriculture (Kislev et al. Science 143:253255, Kerber RE, Rowland GG (1974) Origin of the threshing character in hexaploid wheat. Also, todays wheat varieties have a shallower root system with a large portion of fine roots, so the biomass grows above ground rather than underground. Wheat seeds, fragments, and pollen were not found at Bouldnor Cliff, but the DNA sequences from the sediment match Near Eastern wheat, genetically different from LBK forms. 2011. Their improved yield performance under drought stress conditions appears to be due at least in part to shifts in their rooting profile, whereby a greater proportion of root biomass is produced deeper in the profile (Lopes and Reynolds, 2011; Reynolds et al., 2008).

It grows in sporadic and semi-isolated patches and does best in regions with long, hot dry summers and short mild, wet winters with fluctuating rainfall. Domestication of wheat started with the dawn of human civilization. Of these traits, grain retention and threshability, yield improvement, changes to photoperiod sensitivity and nutritional value are most pronounced between wild and domesticated forms.
