Evolutionists seek to account for differentiation within species-in other words, the emergence of variations-by means of an imaginary mechanism they refer to as micro-evolution. By accumulating over a long period of time, they maintain that small changes can give rise to macro-evolution, in other words the emergence of an entirely new species. (See The Macro-Evolution Myth) In fact, however, there is nothing to do with evolution here. Variation within species occurs with the emergence of individuals with new and different physical characteristics as a result of different combinations of existing genes, through cross-breeding of individuals. However, no new gene is ever added to the gene pool here. All that happens is that genes combine in offspring in new combinations. Since the number and variety of genes in a given species is fixed, there is a limit to the number of combinations that these can give rise to. In addition, variation within a species never produces any new species. For example, no matter how many dogs of different breeds mate together in different combinations, the results will always be dogs, never horses or ferrets. This fixed biological law has been proven through experiment and observation.
Interestingly, Darwin constructed the backbone of his theory on variations he imagined to be micro-evolution. But the advances in biology that gradually undermined Darwin's claims also revealed that the variations he thought accounted for the origin of new species actually bore no such meaning.
For that reason, evolutionist biologists needed to distinguish between variations within a species and the formation of a whole new species, and present these as two distinct concepts.
By using the concept of micro-evolution, evolutionists seek to give the deceptive impression that variations can eventually, gradually give rise to brand new species, families, and orders. Indeed, many people with not much knowledge of the subject become taken in by the superficial idea that when micro-evolution occurs over a long period of time, the result is macro-evolution.
One often encounters examples of this thinking. Some amateur evolutionists suggest that since human beings' average height has increased by 2 centimeters (0.78 of an inch) over a century, so all kinds of major evolutionary changes may take place over millions of years.
The fact is, though, that all variations such as a change in average height take place within specific genetic limits, and these biological variations entirely unrelated to evolution.
In fact, present-day evolutionist authorities admit that the variations they refer to as micro-evolution cannot create new genetic information and thus, cannot give rise to macro-evolution. The evolutionist biologists Scott Gilbert, John Opitz and Rudolf Raff describe this position in a 1996 article published in the journal Developmental Biology:
The Modern Synthesis [the neo-Darwinist theory] 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." 42
The variations that Darwinism has regarded for a century or so as proof of evolution actually have nothing to do with the origin of species. Horses may be crossbred in different combinations for millions of years and different strains of horse may be obtained. Yet horses will never turn into another species of mammal, such as giraffes or elephants. The different chaffinches that Darwin saw on the Galapagos Islands are, in the same way, examples of the variation that constitutes no evidence for evolution. Therefore, the origin of species will remain a question that can never be answered in terms of evolution.
