Wheat Domestication. The major factor underlying human civilization is domestication of plants and animals. 2008. Hirst, K. Kris. From a wild Asian grass to a refined crop that is the staple diet of half the world's population, the domestication of Oryza sativa spans centuries, but the grain's ancestry is hotly contested. Transitions of forms. It was a key event in the agricultural revolution that occurred about 10,000 years ago in the Fertile Crescent of the Middle East. Hybridization between these progenitors less than one million years ago (Marcussen et al., 2014) gave rise to the tetraploid species Triticum turgidum ssp. When was the first domestication of wheat? (2021, June 28). Compared to emmer wheat, modern wheat has shorter leaf longevity, and a higher net rate of photosynthesis, leaf production rate, and nitrogen content.

The founder crops (or primary domesticates) are the eight plant species that were domesticated by early Neolithic farming communities in Southwest Asia and went on to form the basis of agricultural economies across much of Eurasia, including Southwest Asia, South Asia, Europe, and North Africa.They consist of three cereals (emmer wheat, einkorn wheat, and barley), four pulses (lentil, pea .

Human history was transformed with the advent of agriculture in the Fertile Crescent with wheat as one of the founding crops. 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. The domestication phase thus spread over several centuries and simultaneously concerned several species: einkorn ( Triticum monococcum ), emmer wheat ( T. dicoccum ), barley ( Hordeum vulgare) and rye ( Secale cereale) [13], [15].

Rigatoni pomodoro with herb ricotta. Molecular genetics and archaeological data have allowed the reconstruction of plausible domestication scenarios leading to modern cultivars. 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.

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). Its breeding has followed millennia of cultivation, sometimes with unintended selection on adaptive traits, and later by applying intentional but empirical selective pressures.

Another type of early wheat called einkorn (T. monococc) was domesticated at the same time, but is not very common today. It is estimated that wheat provides about 20% of the energy in global diets and about the same percentage of protein (WHEAT, 2014). 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.
