Abstract

fetched live from OpenAlex

Intraspecific variations are the differences in traits among individuals of the same species.These variations are what natural selection acts on, and thus are crucial to evolution by natural selection as proposed by Charles Darwin in his book On the Origin of Species, or the Preservation of Favoured Races in the Struggle for Life.In this text, Darwin proposed multiple sources of intraspecific variation although one of them has yet to be studied despite having been published more than 150 years ago.Darwin explained that traits which are extraordinary compared to the same trait in closely related species ought to be highly variable.In this thesis, I provide possible interpretations of this conjecture, and construct distinct methodologies for testing each interpretation.The quantity and quality of data collected did not allow a decisive test of the conjecture; however, the interpretations and methods described herein may be used to guide future work once the appropriate data are published.

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.

Not 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.
