Abstract
Mammals are not typically thought of as being venomous, yet venom is present in four orders: Monotremata (platypuses and echidnas), Eulipotyphla (shrews and solenodons), Chiroptera (bats), and Primates. Of the monotremes, only the male platypus is venomous, and unlike the other three orders, it envenomates through a hindlimb spur. The other three orders have venoms carried in salivary or other oral secretions and deliver them by biting or licking. Some Eulipotyphlans possess grooved teeth for venom delivery, which helps venom evolution be traced across their phylogeny. In Chiroptera, venom is restricted to the vampire bats for use in feeding, and in primates only certain lorises are venomous. Given the distant relationships in species between the orders, and the variety of environments each lives in, it is highly unlikely venom evolved only once. Instead, it is far more likely that venom evolved multiple times, with each order having its own specific reason. The emergence and retention of venom in mammals have a variety of hypotheses which are discussed and debated below. A particularly interesting case is that of the slow loris, which may have evolved venom for Müllerian mimicry with the spectacled cobra, a venomous species of snake.

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.
