Abstract
Comparative studies of placentation across mammals have been greatly facilitated by the availability of phylogenetic trees for the entire range of placental mammals based on molecular data. The three basic placenta types defined by Grosser on grounds of increasing invasiveness epitheliochorial, endotheliochorial, and hemochorial have routinely served as a basis for comparative discussions. Primates differ starkly from all other placental mammal orders because the two extreme kinds of placentation are represented, while the moderately invasive is not. Reliable inference of the primitive condition is an essential starting-point for successful reconstruction of the evolution of placentation in placental mammals. Having considered the general background to evolution of the placenta in primates, it is now possible to focus specifically on catarrhines Old World monkeys, apes, and humans. The architecture of the placenta is notably different in New World monkeys (platyrrhines), which diverged from catarrhines at least 40 mya.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
