rgenesconverged : An R Package for the Exploration of Molecular Convergent Evolution
Bibliographic record
Abstract
Abstract Sequence convergence is a type of convergent evolution that results in similarity between orthologous genetic sequences. However, this can be difficult to evaluate statistically given classical paradigms for convergent evolution, which rest on the assumption that convergent phenotypes are achieved by unrelated genetic mechanisms. While sophisticated models exist to model this process and to evaluate the probability of this explanation of genetic similarity across two different species, no tool has currently been implemented in R to carry out these analyses. Here we present rgenesconverged , an R package allowing the exploration of sequence convergence hypotheses in a given phylogeny.

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.
