Area of Science:

  • Thermodynamics
  • Biophysics
  • Systems Biology

Background:

  • Life relies on numerous chemical reactions.
  • Understanding life's processes requires a thermodynamic framework.

Purpose of the Study:

  • To formulate entropy for open systems undergoing chemical reactions.
  • To propose entropy production rate as a fitness criterion for natural selection.

Main Methods:

  • Formulation of entropy for open systems.
  • Analysis of entropy production mechanisms.

Main Results:

  • The entropy formula identifies life's fundamental processes (proliferation, differentiation, etc.) as moves toward probable states.
  • Entropy production rate is proposed as the core of natural selection.

Conclusions:

  • The drive towards more probable states organizes matter into functional hierarchies.
  • This thermodynamic perspective offers a unified view of life's organization and evolution.
