Evolutionary theory can be reframed using a triadic structure, integrating Charles 19th-century philosophy and modern thermodynamics. This approach reveals evolution as a physical process governed by the Second Law of Thermodynamics.
Area of Science:
- Evolutionary Biology
- Theoretical Physics
- Philosophy of Science
Background:
- Traditional evolutionary theory often uses dyadic (two-part) frameworks, like organism vs. environment.
- Charles Peirce's philosophy, influenced by Darwin and thermodynamics, offers a foundation for alternative conceptual structures.
- Modern Maximum Entropy (MaxEnt) approaches provide quantitative tools for analyzing evolutionary processes.
Purpose of the Study:
- To propose a triadic conceptual structure for analyzing evolution as an information-generating physical process.
- To synthesize Peirce's theory of signs with modern thermodynamics and evolutionary theory.
- To develop a new diagrammatic approach for understanding evolutionary dynamics.
Main Methods:
- Integrating Peirce's triadic philosophy (semiosis) with Maximum Entropy principles.
- Analyzing autocatalytic cycles using Ulanowicz's framework as a case study.
- Applying a process-based thermodynamic approach to evolutionary dynamics.
Main Results:
- Triadic structures involve efficient, formal, and final causality, accommodating state-centered thermodynamics within a process framework.
- Peircean interpretants are viewed as physical inference systems evolving under natural selection.
- The principles of Maximum Entropy, Maximum Power, and Maximum Entropy Production drive the emergence of information-carrying structures.
Conclusions:
- Evolutionary processes can be understood as a physical manifestation of the Second Law of Thermodynamics.
- A semiotic view of thermodynamics emerges, where information and energy flow gradients are maximized.
- The triadic approach offers a novel perspective on the physical underpinnings of evolution and information generation.

Entropy and the Second Law of Thermodynamics
The relation between entropy and disorder can be illustrated with the example of the phase change of ice to water. In ice, the molecules are located at specific sites giving a solid state, whereas, in a liquid form, these molecules are much freer to move. The molecular arrangement has therefore become more randomized. Although the change in average...

The statement can be further generalized to prove that entropy is a state function. Take a cyclic process between any two points on a p-V diagram.
