Abstract
After 500 million years of evolution, extant land plants compose the following two sister groups: the bryophytes and the vascular plants. Despite their small size and simple structure, bryophytes thrive in a wide variety of habitats, including extreme conditions. However, the genetic basis for their ecological adaptability and long-term survival is not well understood. A comprehensive super-pangenome analysis, incorporating 123 newly sequenced bryophyte genomes, reveals that bryophytes possess a substantially greater diversity of gene families than vascular plants. This includes a higher number of unique and lineage-specific gene families, originating from extensive new gene formation and continuous horizontal transfer of microbial genes over their long evolutionary history. The evolution of bryophytes' rich and diverse genetic toolkit, which includes new physiological innovations like unique immune receptors, likely facilitated their spread across different biomes. These newly sequenced bryophyte genomes offer a valuable resource for exploring alternative evolutionary strategies for terrestrial success.

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
