The most devastating and conclusive argument against evolution is the entropy principle. This principle—also known as the Second Law of Thermodynamics—implies that, in the present order of things, evolution in the "vertical" sense (that is, from one degree of order and complexity to a higher degree of order and complexity) is completely impossible.
The evolutionary model of origins and development requires some universal principle which increases order . . . . However, the only naturalistic scientific principle that is known to effect real changes in order is the Second law, which describes a situation of universally deteriorating order. . . .
The Second Law of Thermodynamics could well be stated as follows: "In any ordered system, open or closed, there exists a tendency for that system to decay to a state of disorder, which tendency can only be suspended or reversed by an external source or ordering energy directed by an informational program and transformed through an ingestion-storage-converter mechanism into the specific work required to build up the complex structure of the system."
If either the information program or the converter mechanism is not available to that "open" system, it will not increase in order, no matter how much external energy surrounds it. The system will proceed to decay. . . .
Whether rank-and-file evolutionists know it or not, this problem they have with
entropy is thus "one of the most fundamental unsolved problems in biology." It
is more than a problem in fact—it is a devastating denial of the evolution model
itself. It will continue to be so until evolutionists can demonstrate that the
vast imagined evolutionary continuum in space and time has both a program to
guide it and an energy converter to empower it. . . .
