Confessions About "Microevolution"


As we have seen, genetic science has discovered that variations, which Darwin thought could account for "the origin of species," actually do no such thing. For this reason, evolutionary biologists were forced to distinguish between variation within species and the formation of new ones, and to propose two different concepts for these different phenomena. Diversity within a species-that is, variation-they called "microevolution," and the hypothesis of the development of new species was termed "macroevolution."

These two concepts have appeared in biology books for quite some time. But there is actually a deception going on here, because the examples of variation that evolutionary biologists have called "microevolution" actually have nothing to do with the theory of evolution. The theory of evolution proposes that living things can develop and take on new genetic data by the mechanisms of mutation and natural selection. However, as we have just seen, variations can never create new genetic information, and are thus unable to bring about "evolution." Giving variations the name of "microevolution" is actually an ideological preference on the part of evolutionary biologists.

The impression that evolutionary biologists have given by using the term "microevolution" is the false logic that over time variations can form brand new classes of living things. And many people who are not already well-informed on the subject come away with the superficial idea that "as it spreads, microevolution can turn into macroevolution." One can often see examples of that kind of thinking. Some "amateur" evolutionists put forward such examples of logic as the following: since human beings' average height has risen by two centimeters in just a century, this means that over millions of years any kind of evolution is possible. However, as has been shown above, all variations such as changes in average height happen within specific genetic bounds, and are trends that have nothing to do with evolution.

In fact, nowadays even evolutionist experts accept that the variations they call "microevolution" cannot lead to new classes of living things-in other words, to "macroevolution." In a 1996 article in the leading journal Developmental Biology, the evolutionary biologists S.F. Gilbert, J.M. Opitz, and R.A. Raff explained the matter this way:

he Modern Synthesis is a remarkable achievement. However, starting in the 1970s, many biologists began questioning its adequacy in explaining evolution. Genetics might be adequate for explaining microevolution, but microevolutionary changes in gene frequency were not seen as able to turn a reptile into a mammal or to convert a fish into an amphibian. Microevolution looks at adaptations that concern only the survival of the fittest, not the arrival of the fittest. As Goodwin (1995) points out, "the origin of species- Darwin's problem-remains unsolved.34
The fact that "microevolution" cannot lead to "macroevolution," in other words that variations offer no explanation of the origin of species, has been accepted by other evolutionary biologists, as well. The noted author and science expert Roger Lewin describes the result of a four-day symposium held in November 1980 at the Chicago Museum of Natural History, in which 150 evolutionists participated:
The central question of the Chicago conference was whether the mechanisms underlying microevolution can be extrapolated to explain the phenomena of macroevolution. …The answer can be given as a clear, No.35
We can sum up the situation like this: Variations, which Darwinism has seen as "evidence of evolution" for some hundred years, actually have nothing to do with "the origin of species." Cows can be mated together for millions of years, and different breeds of cows may well emerge. But cows can never turn into a different species-giraffes or elephants for instance. In the same way, the different finches that Darwin saw on the Galapagos Islands are another example of variation that is no evidence for "evolution." Recent observations have revealed that the finches did not undergo an unlimited variation as Darwin's theory presupposed. Moreover, most of the different types of finches which Darwin thought represented 14 distinct species actually mated with one another, which means that they were variations that belonged to the same species. Scientific observation shows that the finch beaks, which have been mythicized in almost all evolutionist sources, are in fact an example of "variation"; therefore, they do not constitute evidence for the theory of evolution. For example, Peter and Rosemary Grant, who spent years observing the finch varieties in the Galapagos Islands looking for evidence for Darwinistic evolution, were forced to conclude that "the population, subjected to natural selection, is oscillating back and forth," a fact which implied that no "evolution" that leads to the emergence of new traits ever takes place there.36

So for these reasons, evolutionists are still unable to resolve Darwin's problem of the "origin of species."
