From Wild to Cultivated: The Domestication Pathways of Asian Cultivated Rice (<i>Oryza sativa</i> L.)
Bibliographic record
Abstract
The domestication of rice (commonly known as Asian cultivated rice) is a pivotal event in agricultural history, significantly impacting global food security. This review synthesizes current research on the pathways of rice domestication, with a focus on genetic and geographic origins, the role of wild ancestors, and the evolutionary processes involved. Multiple studies indicate that Oryza sativa was independently domesticated from different populations of its wild ancestor, Oryza rufipogon, in various regions of Asia, including southern China, India, and Indochina. Genetic analyses reveal that the two main subspecies, indica and japonica, underwent separate domestication events, followed by gene flow between them. Additionally, the domestication process involved significant genetic changes, such as reduced seed shattering and dormancy, which are crucial for effective cultivation and harvest. This study also explores the impact of human-directed breeding and introgression on the genetic diversity of domesticated rice.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
