Abstract
African terrestrial snails show significant characteristics in terms of evolutionary adaptation and ecological diversity, and their population diversity, genetic structure and distribution pattern are affected by multiple factors such as paleoclimatic change, geological evolution and geographical barriers. This study focuses on the evolutionary origin and diffusion paths of terrestrial snails in Africa, integrates phylogenetic methods and fossil record data, and analyzes molecular phylogenetic, lineage differentiation and niche evolution of representative genera such as Gittenodouardia and Cornu aspersum . Studies have pointed out that climate fluctuations and ecological fragmentation since the Pliocene have significantly promoted the lineage differentiation of multiple spiral genera, while plateaus, river valleys and climate zones constitute diffusion barriers or corridors. Through a comprehensive analysis of mitochondrial DNA, nuclear DNA and paleoecological models, this study not only clarifies the spatiotemporal evolution process of the main lineages, but also provides a new perspective for understanding the adaptation mechanism and diffusion history of African snails.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
