Bio-analog dissipative structures and principles of biological behavior.

Area of Science:

• Thermodynamics
• Philosophy of Science
• Theoretical Biology

Background:

• Historically, organisms were viewed as machines, studied via mechanistic physics and chemistry.
• A thermodynamic perspective recognizes organisms as far-from-equilibrium systems.
• Erwin Bauer proposed early thermodynamic and behavioral frameworks for living matter.

Purpose of the Study:

• To review Erwin Bauer's ideas on the physics of life.
• To explore connections between Bauer's concepts and modern non-equilibrium thermodynamics.
• To contrast mechanistic and thermodynamic views of organisms.

Main Methods:

• Historical review of Erwin Bauer's work.
• Analysis of modern non-equilibrium thermodynamics and dissipative structure theory.
• Comparative evaluation of mechanistic versus thermodynamic frameworks for biology.

Main Results:

• Bauer anticipated thermodynamic and behavioral approaches to life.
• Non-living dissipative structures exhibit life-like properties (e.g., self-maintenance, adaptability).
• Thermodynamic perspectives offer an alternative to the machine-based view of organisms.

Conclusions:

• Organisms can be understood as sophisticated dissipative structures, not just machines.
• A thermodynamic framework, including concepts like dissipative structures, provides new insights into the physics of life.
• Bauer's early work foreshadowed key concepts in modern non-equilibrium thermodynamics and theoretical biology.
