Thermodynamic dissipation theory for the origin of life
K Michaelian - Earth System Dynamics, 2011 - esd.copernicus.org
Understanding the thermodynamic function of life may shed light on its origin. Life, as are all
irreversible processes, is contingent on entropy production. Entropy production is a …
