Abstract

fetched live from OpenAlex

Going Multicellular The volvocine algae include both the unicellular Chlamydomonas and the multicellular Volvox , which diverged from one another 50 to 200 million years ago. Prochnik et al. (p. 223 ) compared the Volvox genome with that of Chlamydomonas to identify any genomic innovations that might have been associated with the transition to multicellularity. Size changes were observed in several protein families in Volvox , but, overall, the Volvox genome and predicted proteome were highly similar to those of Chlamydomonas . Thus, biological complexity can arise without major changes in genome content or protein domains.

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 distilled prediction

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.
