Abstract
Elongation factor-1 alpha (EF-1α) is already widely used and shows even more promise for phylogenetic studies of Hexapoda. However, paralogous copies and the presence of introns pose problems. We survey exon-intron structure, presence of paralogous copies and the number and extent of sequenced regions in all hexapod orders. We assess the phylogenetic utility of the exon-intron structure of EF-1α, which is unexpectedly dynamic with widespread losses and several independent instances of intron gain. Paralogous copies of EF-1α are present in Hemiptera, Thysanoptera, Neuropterida, Coleoptera, Hymenoptera and Diptera. With the presented information about exon-intron structure and paralogous copies, researchers will be able to realise the full phylogenetic potential of EF-1α, including exon-intron structure as this can provide additional characters and help to define clades and paralogous copies. We recommend a suitable focus region of 500 bp for future studies of EF-1α in Hexapoda.

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
