Abstract
This study mainly aims to analyze the evolutionary differences between chickens and wild chickens. We focus on the morphological, physiological, behavioral and genetic changes during the domestication process. Some commonly used tools in research include whole-genome SNPS, mitochondrial DNA and microsatellites, etc. These can help us observe the differentiation and gene exchange between domestic chickens and wild free-range chickens. It was found that domestic chickens exhibited distinct domesticated characteristics in terms of body size, feather color, breeding season, metabolism and response to humans. These changes are closely related to some key genes, such as TSHR, BCO2 and IGF1. In addition, the genes of domestic chickens are also mixed with components from other wild species such as the grey pheasant, making their genetic background more diverse. Phylogenetic analysis also indicates that the domestication and spread of domestic chickens were not accomplished in one go, but rather involved multiple origins and complex gene exchanges, which is why there are significant differences among domestic chicken breeds in different regions. The purpose of this review is to better understand the mechanism and genetic basis of domestic chicken domestication, and also to provide some references for poultry breeding and conservation.

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 it
