Evolution, Thermodynamics, and Entropy

Evolution, Thermodynamics, and Entropy


The study of biological processes and phenomena indicates that significant evolutionary developments are not observable in the modern world. Similarly the great gaps in the fossil record make it extremely doubtful that any genuine evolution, as distinct from small changes within the kinds, ever took place in the past.
There is one consideration, however, which goes well beyond the implications of the above difficulties. Not only is there no evidence that evolution ever has taken place, but there is also firm evidence that evolution never could take place. The law of increasing entropy is an impenetrable barrier which no evolutionary mechanism yet suggested has ever been able to overcome. Evolution and entropy are opposing and mutually exclusive concepts. If the entropy principle is really a universal law, then evolution must be impossible.
The very terms themselves express contradictory concepts. The word "evolution" is of course derived from a Latin word meaning "out-rolling". The picture is of an outward-progressing spiral, an unrolling from an infinitesimal beginning through ever broadening circles, until finally all reality is embraced within.
"Entropy," on the other hand, means literally "in-turning." It is derived from the two Greek words en (meaning "in") and trope (meaning "turning"). The concept is of something spiraling inward upon itself, exactly the opposite concept to "evolution." Evolution is change outward and upward, entropy is change inward and downward.
That the principles of evolution and entropy are both believed to be universal principles and yet are mutually contradictory is seen from the following authoritative definitions:
"There is a general natural tendency of all observed systems to go from order to disorder, reflecting dissipation of energy available for future transformation—the law of increasing entropy." 1
As far as evolution is concerned, the classic definition of Sir Julian Huxley is as follows:
"Evolution in the extended sense can be defined as a directional and essentially irreversible process occurring in time, which in its course gives rise to an increase of variety and an increasingly high level of organization in its products. Our present knowledge indeed forces us to the view that the whole of reality is evolution—a single process of self-transformation."2
Thus, in one instance, "all observed systems ... go from order to disorder," and in the other, "the whole of reality ... gives rise to an increasingly high level of organization in its products." It seems obvious that either evolution or entropy has been vastly over-rated or else that something is wrong with the English language.
The entropy principle, however, is nothing less than the Second Law of Thermodynamics, which is as universal and certain a law as exists in science. First, however, before discussing the Second Law, we should define the First Law and, for that matter, thermodynamics itself.
Thermodynamics is a compound of two Greek words, therme ("heat") and dunamis ("power"). It is the science that speaks of the power or energy contained in heat, and its conversion to other forms of energy. The term "energy" is itself derived from the Greek word energeia ("working"), and is normally defined as "the capacity to do work." In modern scientific terminology, "energy" and "work" are considered equivalent, each measured as the product of a force times the distance through which it acts (foot-pounds, in the English system of dimensions). Something which has "energy" has the "capacity to do work" ... that is, the capacity to exert a force through a distance."
The concept of "power" is closely related to that of "energy" except that the time factor must also be taken into account. Power is the work done, or the energy expended to do the work, per unit of time measured in foot-pounds per second.

The First Law of Thermodynamics

Since all processes are fundamentally energy conversion processes, and since everything that happens in the physical universe is a "process" of some kind, it is obvious why the Two Laws of Thermodynamics are recognized as the most universal and fundamental of all scientific laws. Everything that exists in the universe is some form of energy, and everything that happens is some form of energy conversion. Thus the Laws which govern energy and energy conversion are of paramount importance in understanding the world in which we live.
Isaac Asimov defines the First Law as follows:
"To express all this, we can say: ‘Energy can be transferred from one place to another, or transformed from one form to another, but it can be neither created nor destroyed.’ Or we can put it another way: ‘The total quantity of energy in the universe is constant.’ When the total quantity of something does not change, we say that it is conserved. The two statements given above, then, are two ways of expressing ‘the law of conservation of energy.’ This law is considered the most powerful and most fundamental generalization about the universe that scientists have ever been able to make."3
Asimov makes a very interesting point when he says concerning this Law: "No one knows why energy is conserved."4 He should have said, of course, that science cannot tell us why energy is neither created nor destroyed. The Bible, however, does give us this information.
The reason why no energy can now be created is because only God can create energy and because God has "rested from all His work which He created and made" (Genesis 2:3). The reason why energy cannot now be destroyed is because He is now "upholding all things by the word of His power" (Hebrews 1:3). "I know that, whatsoever God doeth, it shall be forever: nothing can be put to it, nor anything taken from it" (Ecclesiastes 3:14).

The Second Law in Classical Thermodynamics

The First Law is itself a strong witness against evolution, since it implies a basic condition of stability in the universe. The fundamental structure of the cosmos is one of conservation, not innovation. However, this fact in itself is not impressive to the evolutionist, as he merely assumes that the process of evolution takes place within the framework of energy conservation, never stopping to wonder where all the energy came from in the first place nor how it came to pass that the total energy was constant from then on.
It is the Second law, however, that wipes out the theory of evolution. There is a universal process of change, and it is a directional change, but it is not an upward change.
In so-called classical thermodynamics, the Second Law, like the First, is formulated in terms of energy.
"It is in the transformation process that Nature appears to exact a penalty and this is where the second principle makes its appearance. For every naturally occurring transformation of energy is accompanied, somewhere, by a loss in the availability of energy for the future performance of work."5
