Abstract

fetched live from OpenAlex

Questions concerning the origin of parthenogenesis in Caucasian Rock Lizards and genetic divergence among bisexual lizards of the Lacerta raddei complex were examined using sequences from the mitochondrial cytochrome b gene. The maternal parent of the parthenogenetic L. uzzelli, L. sapphirina, and L. bendimahiensis was confirmed to be L. raddei. Although substantial variation was revealed among bisexual populations of L. raddei and L. nairensis, very low or no variation was found among the parthenogenetic species. A phylogenetic tree including 11 populations of L. raddei and L. nairensis, as well as 10 populations of its five daughter parthenogens, was constructed. Because of paraphyletic relationships, L. nairensis is considered conspecific with L. raddei. Evaluation of the parthenogenetic species suggests that separate hybridization events between L. raddei and L. valentini might have occurred at least twice. One resulted in L. sapphirina and L. bendimahiensis, and the other one (or more) resulted in L. unisexualis and L. uzzelli. The females involved were distantly related, Lacerta unisexualis and L. uzzelli likely had separate origins, but the females involved were closely related.

Teacher imitation

Not 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.
