The
Inevitability of Life Kauffman proved that life is vastly more probable than traditionally assumed. The US physicist Jeremy England ("Statistical physics of self-replication", 2013) showed that when matter is driven by a strong external source of energy (like the sun) and surrounded by a heat bath (like the sea), it tends to restructure itself in order to dissipate increasingly more energy, i.e. to behave like living matter. That restructuring can occur in many ways but two are obvious: self-replication and self-organizing. These are two processes that cause (allow?) a system to dissipate increasingly more energy. The Belgian (but Russian-born) physicist Ilya Prigogine had analyzed the
behavior of open systems near equilibrium. The behavior of systems that are far
from equilibrium because driven by stronger external sources of energy was
studied by the Australian physicist
Denis Evans ("Probability of Second Law Violations in Shearing Steady
States", 1993) and by the Polish physicist Chris Jarzynski ("Nonequilibrium Equality for Free Energy Differences",
1997). Then the British chemist Gavin Crooks ("Entropy production fluctuation theorem and the
nonequilibrium work relation for free energy differences", 2008)
discovered a simple law: the probability that atoms will undergo a
thermodynamic process divided by the probability of the same atoms undergoing
the reverse process (such as reconstituting the original lump of sugar)
increases as entropy production increases. In other words, the systems
behavior becomes more and more irreversible. From these observations England
derived his theory. At the same time others
showed that self-replication is not a property of living beings alone. Philip
Marcus ("Three-Dimensional
Vortices Generated by Self-Replication in Stably Stratified Rotating Shear
Flows", 2013) and Michael Brenner ("Self-replicating
colloidal clusters", 2013) have discovered it in nonliving matter too. Back to the beginning of the chapter "The Evolution of Life: Of Designers and Design" | Back to the index of all chapters |
