HHS Vulnerability Disclosure, Help 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. The main difference between wild forms and domesticated wheat is; domesticated wheat has larger grains with rind and semi-brittle stems. Other scientists are skeptical about the identity of the period and DNA, saying the findings are too good to be that old.

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.
