Scientific work which refutes the claim that the theory of evolution
contradicts
or violates the Second Law of Thermodynamics, has been awarded the 1977 Nobel
Prize in Chemistry. Dr. llya Prigogine's work extends the laws of
thermodynamics
to systems far from equilibrium. The Second Law of Thermodynamics is
often described
as if it applied to all systems under all circumstances and
conditions. Although
the Second Law predicts that reactions of matter near equilibrium
conditions tend
toward greater homogeneity and less complexity, there are many
reactions in natural
systems far from equilibrium that increase in complexity.
Prigogine's initial observation of this type of reaction in hydrodynamics was
the formation of convection currents and vortices in a fluid
subjected to a temperature
gradient. Such systems are
maintained at the cost of some energy (the fluid being unevenly
heated). Vortices
are highly correlated motions and convection currents are orderly and
directional.
Non-equilibrium differences of temperature create molecular order.
Prigogine admitted
that the theorem of minimum entropy production for near equilibrium
systems that
he proposed in 1945, is not valid. His Nobel Prizewinning work indicates that
the condition necessary so that new structures may appear is a
catalytic or cross-catalytic
step.
Many reactions of this type have since been discovered experimentally
in biological
systems. Life processes work under nonequilibrium systems, and living
matter consists
of structures that exist in states that are far from equilibrium.
Examples cited
are the growth of an entire plant from a seed and the formation of amino acids
from primordial soup. Nature is full of processes that spontaneously
bring order
from chaos and that thrive in seeming contempt of the Second Law of
Thermodynamics.
Prigogine's work reconciled the Second Law with the obvious facts of life. He
realized that in certain systems - self-catalytic chemical reactions,
for example
- perturbations that get far enough away from thermal equilibrium
will no longer
subside but will continue to grow. Such a system eventually can reach
a new, stable
configuration far from equilibrium; it will then maintain itself
against thermal
disruption by a continuous throughput of matter and energy, which
carry off internally
generated entropy to the outside.
Prigogine's work, according to his article in Physics Today,
November 1972, may be providing a theoretical framework for understanding the
ultimate example of 'self-catalysis" - the origin of life. Only the unwary
or uninformed would fall prey to the invalid argument that the Second
Law of Thermodynamics
contradicts biological evolution.
