Only the Bible explains the diversity of life


Fig. 1. Chihuahua and Great Dane. Both came from the same ancestral stock, which had more information, more variety than either of these. Breeding from a Chihuahua can never lead to a Great Dane and, similarly, breeding from a Great Dane can never lead to a Chihuahua. Some define species as populations which cannot freely and naturally interbreed, so these two might even qualify as separate species. But all of the information was already present in the original ‘mongrel’ population—selection is not a creative process.

Evolutionists often misrepresent biblical creationists, saying that we claim that one species cannot change into another—that we believe in the ‘fixity of species’. They then present undeniable evidence that species can change and argue that they have shown us to be ignorant of scientific facts. This, of course, is nonsense. Those who base their understanding of the natural world on the Bible do not believe in the fixity of species. Rather, we believe in the ‘fixity of kinds1, i.e. that one kind cannot change into another. (See Genesis 1:11–12, 1:21 and 1:24–25.) Hence finches may turn into other species of finch, or fruit flies into other species of fruit fly; but finches will never turn into hawks or fruit flies into wasps. Nor will apes ever turn into people.

According to the Bible, except for those preserved in the Ark, all air-breathing land animals were destroyed in the global Flood2 described in Genesis 6–8. God commanded Noah to take into the Ark pairs of every kind of animal. Noah did not take representatives of every species, but every kind. For example, there would have been a pair of the dog kind aboard, a pair of the cat kind, and seven pairs of the cattle kind—not just two, as this was a ‘clean’ animal (Genesis 7:2). In the centuries following the Flood, all of the different dogs (wolves, coyotes, jackals etc.), the different cats (lions, tigers, leopards etc.) and the different cattle (bison, yaks, domestic cattle, etc.) would have arisen from these kinds. But how did this happen?

Variation and selection

All animals have DNA,3 which determines what sort of animal they grow into. So, change the DNA and you will change the form of the animal! Animals inherit DNA from both the mother and the father, and the offspring have various combinations of their parents’ DNA. This, of course, is also true of humans and explains why we’re all different.

For example, some are taller, some shorter; some have darker skin, others lighter skin. All humans are descended from Adam and Eve, whose DNA was such that all their offspring, although different in many ways, are still all of the same species—Homo sapiens. The DNA of the animals preserved on the Ark, however, would have enabled greater variation in their offspring, to the point that different combinations of the males’ and females’ DNA have in many instances produced different (though still similar) species.

The Genesis account makes clear that God brought the animals to the Ark4 (Genesis 6:19–20). God chose the male and female of each pair and thus what mix of DNA would be passed down to each of the offspring. Immediately following the Flood, speciation could have been very rapid, perhaps arising within just a few generations. Later, this diversification would have been slower, as ‘survival of the fittest’ helped shape the emerging populations.

Breeders carefully select particular males and females for mating, generation after generation, in order to produce the particular characteristics they want. (See fig. 1.) In the wild, males and females best suited to their environment will thrive and produce the most offspring and, over the generations, their characteristics will come to dominate within the group. For example, bears with white fur living in the arctic will hunt more successfully than brown bears as they are better camouflaged. When practised by breeders this process is known as ‘artificial selection’; in the wild it is known as ‘natural selection’.

Both these processes act like a sculptor working on a statue.5 The sculptor carves away the material that he doesn’t want. Similarly, artificial selection and natural selection remove the DNA that produces undesirable characteristics, leaving just the characteristics that the breeder wants or, in the wild, those characteristics that enable the animals to thrive within a given environment. Moreover, just as the sculptor, if he keeps carving, will eventually run out of material, so artificial selection and natural selection eventually run out of DNA. After a while, no more characteristics can be removed and the breeder and nature cannot change the organism any more. This is why, however much you breed dogs or pigeons or horses, they always remain dogs, pigeons, and horses.

Programmed adaptation

Animals can also adapt to their environments by selecting which parts of the DNA (i.e. which genes) will be used and which will not. So, instead of removing unwanted genes (as in the previous section), they are simply switched off. Similarly, genes that are wanted can be switched on.

Fig. 2. Some Italian Wall Lizards (Podarcis sicular) were moved from Pod Kopište to Pod Mrčaru, off the coast of Croatia. Remarkable changes were seen in their head sizes and head shapes within less than 38 years.

In 1971, some lizards were moved from one island to another off the coast of Croatia.6 Although similar in climate, the two islands afforded very different types of food. The island from which the lizards were taken provided a diet mainly of insects, whereas the new island provided a diet mainly of plants. In less than 38 years, the lizards that had been moved to the new island had changed significantly. Remarkable changes were seen in their head shapes and head sizes, which scientists think arose to increase their bite force. Significant changes were also seen in their gut morphology (the internal shape of their stomachs). In fact, they had even grown a new ring of muscle in their stomachs to slow down the passage of food to aid digestion of the plant material. All this in less than 38 years! Such rapid changes clearly have nothing to do with Darwin’s theory of evolution, which requires that lucky, useful mutations accumulate over hundreds of thousands or millions of years, gradually changing the animals’ form.7

So that’s another way that speciation could have occurred—by programmed change, that is by changes driven by the program in the DNA which God put into animals when he first made them, and triggered by changes in the environment—in this case, a new food source.

Is this evolution?

No! Fundamental to the Darwinian process is the need to generate useful, new DNA. Microbes do not have arms, legs, hearts or brains because they do not have DNA containing the building instructions (the genetic information) to grow such things. If Darwin’s theory were true, and microbes turned into men, there must be a process in nature that can generate DNA with new building instructions. If scientists cannot point to such things happening today then the evolution story has no place in science.

Evolutionists claim that the work of breeders, and observations of speciation in nature, demonstrate the truth of evolution8. But this is not so. When new varieties arise through artificial selection or natural selection, genetic information is not increased, but decreased. The new breeds and new species have fewer building instructions than the original animals, because the unwanted DNA information has been whittled away. How can examples of reduction of genetic information be evidence of a process that, fundamentally, requires an increase in genetic information?

Similarly, when animals like lizards change through switching genes on and off, there is no increase in genetic information: the process of adaptation occurs through using existing building instructions.

Secularists know that if they can convince people of evolution then they will think that there’s no need to believe in a creator God. As such, they search for the very best arguments they can think of, the ones which make evolution appear most scientific. What are these arguments? Invariably, they are examples of change where there is either no evidence of increased genetic information or clear cases of loss of genetic information. If they had real examples of evolution, they would surely present them. The fact that they don’t makes abundantly clear that such examples don’t exist.

Do mutations produce new genetic information?

Evolutionists argue that mutations can generate new genetic information. Indeed, they often claim to have observed such evolutionary processes in action1. Let’s look at some examples.

Antibiotic resistance

Soon after doctors started to treat patients with the antibiotic streptomycin, some bacteria became resistant to it through mutation. Streptomycin works by attaching itself to the ribosome (a machine inside the bacterium which produces its proteins) preventing it working properly. Various mutations were observed which changed the shape of the ribosome preventing the streptomycin attaching itself and interfering with protein production. However, these mutations had a downside, as the ribosome worked more slowly. Hence, although the bacteria gained resistance to streptomycin, this was associated with a loss of function. Significantly, the reduction of protein production would have been disadvantageous outside of the artificial environment created by the drug treatment.2

Pesticide resistance

Warfarin is routinely prescribed by doctors to patients vulnerable to blood clotting. When used in higher doses, it can be a very effective pesticide3, and has been used to cull populations of rats. The warfarin is so effective in preventing the rats’ blood clotting that they die from internal bleeding. It works by interfering with the way the rats process Vitamin K, which is needed to clot the blood. However, within a few years some rats had acquired resistance. A mutation had arisen that led to an enzyme used to process the Vitamin K being unaffected by the warfarin. Again, however, there was a downside. The new enzyme processes Vitamin K very inefficiently, to the extent that the rats need around ten times as much Vitamin K to survive—even if there’s no warfarin around. These rats often die because there is not enough Vitamin K in their food. This is hardly a great example of an evolutionary process!4

Malaria resistance

Some people have gained a degree of immunity from malaria. They carry a mutation that causes blood cells infected with malaria to change shape (to become ‘sickled’) and be destroyed by the spleen, an organ in the body that filters the blood.5 Evolutionists have made much of this as a clear example of evolution. However, the mutation also makes carriers more vulnerable to a number of other diseases,6and only confers resistance to malaria if the person inherits the mutation from just one parent. In fact, if the mutation is inherited from both parents, the child will develop a serious disease called Sickle Cell Anemia7, which is often fatal.8 This is a very strange sort of evolution! The more people that carry the mutation, the more children will die from Sickle Cell Anemia. In practice, in areas where there is a significant risk of malaria, the number of carriers tends to be limited to only 18% of the population.9

Fig. 3. Normal and ‘sickled’ red blood cells.

Cornell University geneticist Dr. John Sanford commented:

“It must be understood that scientists have a very sensitive and extensive network for detecting information-creating mutations and most geneticists are diligently keeping their eyes open for them all the time. … Yet I am still not convinced there is a single, crystal-clear example of a known mutation which unambiguously created information.”10

At CMI we do not argue that information-increasing mutations could never happen.11 However, if evolution were true, there must have been countless billions of these in the past. Why, then, don’t we see them occurring all around us today?

This article is right on time for me. I just started the Summer Semester and I am taking a Biology class called "Principles of Biology". The information in this article and elsewhere on the CMI site has equipped me to "fight the good fight" for truth in this secularized world and I thank you for that.

There are two points I'd like to make:

1. It is well established that all dogs are artificially selected, (bred) from a very well adapted wolf kind. There is no doubt in my mind that if all dogs were to become feral, (wild) the vast majority would go extinct soon after because we humans are artificially keeping them alive by feeding them. They are no longer well adapted to the environment because natural selection has been restrained.

2. The observed lizard mutation allowing adaptation to a different environment, (island) by switching on and off certain gene packages denotes sophisticated programming. Where there is sophisticated programming, there is a sophisticated programmer. It is blatant proof of a super intelligent creator. Further more it becomes apparent to me maybe the whole reason God created by sexes, male and female, (rather than asexual reproduction) is to facilitate the recombination of gene packages to produce the diversity of kinds we observe in our environment today.

When you examine nature, (even in its fallen state) you have to wonder what a great and wise creator God we have.

Loved this article! It stabs at the heart of the evolutionary fairy tale.
Bill H.
I believe the name of the article, "Only the Bible explains the diversity of life" states it all.

Excellent information.

Thanks for all the hard work and research done by all there at CMI

May the Lord Jesus Christ richly bless all there

With those changes in the lizards, couldn't evolutionists argue that it was punctuated equilibrium? I just wonder if we actually know whether it was programmed changes. I would say the best explanation is program changes but a new ring of muscles seems like quite an extreme change.
Dominic Statham
Punctuated equilibrium is not an explanation for how evolution could have happened. It's simply a statement of belief that evolutionary steps occurred over short periods of time interspersed with long periods when evolution did not occur (stasis).

In order for evolution to appear plausible, evolutionists need to point to processes in nature that can increase complexity and associated genetic information. As we show in many articles on, there are no such processes known in nature, even given millions of years for this to happen. The idea that new genetic information could be generated by random mutations on a scale that could produce a new valve in the stomach of lizards in just tens of years is absurd. It is precisely because this is such an 'extreme change' that the information must already have existed in the lizards' genome. All that was required was for this to be switched on.
Gordon S.
One is often reminded of something said over 100 years ago:"There is a particle of truth in every error which is what makes it so dangerous. I think this is certainly true of most errors connected with evolution.
