Reassessing domestication events in the Near East: Einkorn and <i>Triticum urartu</i>
Bibliographic record
Abstract
To reassess domestication events in the Near East, accessions of Triticum urartu from a well-described sampling were combined with a representative sample covering the Karacadağ Einkorn wheat domestication. The observed DNA separation between the two wheat species accounts for the main differentiation, but geographic variation within T. urartu is evident and so is the domestication scenario among wild, feral, and domesticated Einkorn. In contrast to the clear DNA differences, it is difficult to separate living T. urartu from wild Einkorn based on morphology. With archaeobotanical material a distinction of carbonized remains of these two wheats is considered to be impossible. We reviewed the differences concerning morphology and maturity and combined these observations with information about archaeological sites in the Near East. In conclusion, the excavation sites in the middle Euphrates may contain T. urartu rather than Einkorn wheat and T. urartu may underlie the reported occurrence of the extinct 2-grained domesticated "Einkorn" wheat. The first Einkorn wheat domestication sensu stricto seems to have happened around the Karacadağ, as reported earlier. The human dimension shown by the excavation of Göbekli Tepe can explain why domesticated phenotypes might have spread quickly.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
