Phylogeny of the rock-wallabies, <i>Petrogale</i> (Marsupialia : Macropodidae) based on DNA/DNA hybridisation
Bibliographic record
Abstract
DNA/DNA hybridisation analysis was undertaken to resolve the phylogenetic relationships within the chromosomally diverse genus Petrogale . Excepting P. concinna , all full species and three subspecies of P. lateralis were examined; all but four of these 16 taxa were labeled, as were four outgroup species. While demonstrating the ability of the technique to resolve relationships at the species level, our study confirmed that divergence of Petrogale species is recent and occurred during the late Pliocene to mid-Pleistocene. Our data placed the first division within Petrogale species between the monophyletic brachyotis group and the paraphyletic xanthopus plus lateralis / penicillata groups, the latter including P. rothschildi ; the subspecies P. l. purpureicollis appears to be intermediate between the lateralis and the penicillata complexes. However, our data could not resolve most relationships amongst the eastern Petrogale radiation, except for a probable grouping of the species P. herberti , P. inornata , P. penicillata , and P. sharmani . Finally, our results support recent suggestions that Dendrolagus rather than Thylogale is the sister taxon to Petrogale .

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.
