HLRP #143: Accretion Chaining — Geometric Coupling Theory

Key Points

• To propose a sequential accretion model for the origins of vertebrate organs based on metabolic incorporation.
• Develop a theoretical framework extending serial endosymbiosis to organism-scale processes.
• Analyze the role of refused digestion in structural incorporation of biological materials.
• Discuss implications for evolutionary innovation and speciation.
• Metabolic incorporation is shown to facilitate organ development and evolutionary change.
• Refused digestion is identified as a significant mechanism for structural incorporation.
• The model provides new insights into the processes underlying vertebrate diversity.
