Five Major Misconceptions about Evolution

Evolution has never been observed. Evolution violates the 2nd law of thermodynamics. There are no transitional fossils. The theory of evolution says that life originated, and evolution proceeds, by random chance. Evolution is only a theory; it hasn't been proved.

"Evolution has never been observed." Biologists define evolution as a change in the gene pool of a population over time. One example is insects developing a resistance to pesticides over the period of a few years. Even most Creationists recognize that evolution at this level is a fact. What they don't appreciate is that this rate of evolution is all that is required to produce the diversity of all living things from a common ancestor.

What hasn't been observed is one animal abruptly changing into a radically different one, such as a frog changing into a cow. This is not a problem for evolution because evolution doesn't propose occurrences even remotely like that. In fact, if we ever observed a frog turn into a cow, it would be very strong evidence against evolution.

"Evolution violates the 2nd law of thermodynamics." The second law of thermodynamics says, "No process is possible in which the sole result is the transfer of energy from a cooler to a hotter body.” Okay…what does that mean? Order can arise from disorder…life is irrelevant to the 2 nd Law of Thermodynamics.

"There are no transitional fossils." A transitional fossil is one that looks like it's from an organism intermediate between two lineages, meaning it has some characteristics of lineage A, some characteristics of lineage B, and probably some characteristics part way between the two. There are lots of them.

"The theory of evolution says that life originated, and evolution proceeds, by random chance." Chance certainly plays a large part in evolution, but this argument completely ignores the fundamental role of natural selection, and selection is the very opposite of chance. Chance, in the form of mutations, provides genetic variation, which is the raw material that natural selection has to work with. From there, natural selection sorts out certain variations.

"Evolution is only a theory; it hasn't been proved." First, we should clarify what "evolution" means. Its strict biological definition is "a change in allele frequencies over time.” The argument rests on a confusion between what "theory" means in informal usage and in a scientific context. A theory, in the scientific sense, is "a coherent group of general propositions used as principles of explanation for a class of phenomena" [Random House American College Dictionary]. The term does not imply tentativeness or lack of certainty.
