The Dual-Lineage Carnivory Framework: Comparative Evolution of Canids, Felids, and Humans Across Trophic Level, Metabolic, Physiological, Genomic, and Behavioural Systems

This record contains the supplementary materials for the paper titled The Dual-Lineage Carnivory Framework: Comparative Evolution of Canids, Felids, and Humans Across Trophic Level, Metabolic, Genomic, and Behavioural Systems. These materials provide extended definitions, tables, notes, and methodological details that support the main manuscript. The supplementary package includes expanded content on the carnivory engine, domestication pathways, metabolic engine convergence, neurocognitive bonding circuitry, and the evolutionary timelines of dogs, cats, and humans. Additional sections offer detailed comparative anatomy notes, sensory evolution commentary, metabolic engine tables, and a dedicated subsection on the Randle cycle as a shared carnivory metabolic switch across the triad. Further materials include behavioural evolution notes, genomic signature tables, ecological niche commentary, falsifiable prediction detail, and extended methodological guidance for genomic sequencing, metabolic profiling, behavioural assays, comparative anatomy, and trophic level biomarker analysis. These supplementary materials are intended to accompany the full preprint, which will be submitted separately to a preprint publication journal. They provide additional depth and clarity for readers, reviewers, and researchers engaging with the comparative evolutionary model presented in the main paper.
