Abstract

fetched live from OpenAlex

ABSTRACT Connecting natural selection of phenotypes with molecular evolution is one of the central goals of evolutionary biology. Using phylogenetic methods, I tested the hypothesis that reproductive conflicts related to sperm competition drive the adaptive molecular evolution of primate reproductive proteins. To control for potential empirical or statistical biases in the data, I compared results from 22 ‘housekeeping’ proteins, to those of 28 reproductive proteins. Positive correlations between sperm competition and adaptive molecular evolution were significantly greater amongst reproductive proteins than amongst control group proteins. Reproductive proteins implicated in seminal coagulation and sperm-egg interactions, including two female-expressed proteins, had particularly high correlation coefficients. These results suggest that inter- as well as intra-sexual reproductive conflicts generate adaptive divergence in reproductive proteins. The nature of molecular interactions may mean that reproductive conflicts between males and females at this level are particularly likely to lead to the reproductive isolation of allopatric populations.

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.
