Evolution and diversification of Mountain voles (Rodentia: Cricetidae)
Bibliographic record
Abstract
The systematics of the Cricetid genus Neodon have long been fraught with uncertainty due to sampling issues and a lack of comprehensive datasets. To gain better insights into the phylogeny and evolution of Neodon, we systematically sampled Neodon across the Hengduan and Himalayan Mountains, which cover most of its range in China. Analyses of skulls, teeth, and bacular structures revealed 15 distinct patterns corresponding to 15 species of Neodon. In addition to morphological analyses, we generated a high-quality reference genome for the mountain vole and generated whole-genome sequencing data for 47 samples. Phylogenomic analyses supported the recognition of six new species, revealing a long-term underestimation of Neodon diversity. We further identified positively selected genes potentially related to high-elevation adaptation. Together, our results illuminate how climate change caused the plateau to become the centre of Neodon origin and diversification and how mountain voles have adapted to the hypoxic high-altitude plateau environment.

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.
