Evolutionists look at examples of animals adapting to their environments, and they assume that in this way, given enough time and enough tiny changes, primitive frogs have turned into turtles, and fish into philosophers.

Creationists have long agreed that inheritable adaptation happens via natural selection.1 This helps explain how the kinds represented on the Ark were able to rapidly diversify afterwards into many different varieties, even new species.2

On its own, natural selection can only sort (or get rid of) existing information. It cannot generate any new information or variability itself; it can only choose from what is already there. Genes come in pairs,3 are reshuffled at reproduction, and many exist in at least two forms, so living things have a lot of built-in variability already. Thus the ‘dog kind’ pair on the Ark could have diversified rapidly into coyotes, dingoes, wolves, etc. without any genetic novelty necessarily introduced into their DNA.

Such variation is a downhill genetic process, involving a loss of genetic information, as has been documented for decades.4 It does not constitute ‘evolution’ as commonly understood, which would require an overall uphill process, with lots of new information arising along the way.

The standard source of the new information needed in evolutionary theory has long been mutations—inherited changes in the DNA which until recently have been assumed to be almost exclusively random, i.e. genetic copying mistakes.

Standard neo-Darwinian evolutionary theory has long insisted that all mutations are random. But there is increasing evidence that this is not always the case.

Creationists agree that mutations happen frequently; in fact they are accumulating so rapidly that it seems no amount of selection can halt the eventual extinction of all non-microbial populations within thousands, not millions of years.5

And creationists also agree that even a random genetic change can sometimes confer a definite survival advantage in special environments, which helps explain how some new species have emerged since the Flood of Noah. Take, for instance, the mutations that caused a loss of melanin in the hair follicles of polar bears, or wingless beetles and birds on windy islands,6 and blind fish in caves.

These sorts of mutations, along with reproductive genetic variation and natural selection, provide a perfect recipe for generating many ‘species’ in just a few thousand years since the various created animal ‘kinds’ spread out from the Ark landing site. But such obvious losses of information highlight the general problem for evolution; that overall, the processes of genetic change are overwhelmingly heading in the wrong direction for microbes to become microbiologists.7

Mutations—not all random

Can mutations ever add information? There has been some debate over this, which reflects some of the difficulty in defining information.8 But it does seem that mutations are sometimes capable of introducing novel genetic content into the DNA of a group of organisms, on which selection can then act to cause adaptation. However, when this happens, is such novelty always random? Or can it sometimes be, as seems to be gradually becoming apparent, the result of some sort of functional system designed and intended for some degree of adaptation?

The ability to adapt … is likely a designed feature of organisms—Immunologist Donald Ewert

Standard neo-Darwinian evolutionary theory has long insisted that all mutations are random. But there is increasing evidence that this is not always the case—and that when animals adapt to various environments, they (at least sometimes) can do so under the control of some sort of functional system designed for adaptation.

A growing number of evolutionary biologists are acknowledging that generating the genetic changes for adaptation is not always a blind process. For instance, it is known that rapid mutations in special places in DNA can play a key role in the adaptation of organisms to their environment.9

Also, as noted in an important evolutionary book, “until recently [biologists] have been very reluctant to concede that … mutations might be formed specifically when and where needed … It was simply assumed that all mutations are blind mistakes.”10 But now, an increasing number of scientists acknowledge that when mutations (i.e. inheritable changes in DNA) lead to adaptation, “not all … are haphazard mistakes; rather, some mutations are ‘directed’.”11

Indeed, it appears that regulated non-random controls can be involved when animals adapt to their environments.12,13,14

Adaptation—predictable, thus non-random

Accumulating research has shown that adaptability can be predictable.15 It appears that organisms can at times actually change and adapt in response to their environment.12 It is now known that an animal’s environment may alter or activate specific genes in specific locations which results in a specific trait that can enable the animal to adapt and survive better in its new environment.13 Such occurrences are repeatable and thus predictable.

Nature: [individual organisms can proactively] “respond to their environment by changing their form … to generate traits that are well-suited to them.”

As published in the prominent science journal Nature, individual organisms can proactively “respond to their environment by changing their form … to generate traits that are well-suited to them”.

Examples include “the jaws of cichlid fishes that change shape when food sources alter, to leaf-mimicking insects that are brown if born in the dry season and green in the wet”.12

All of this implies that an engineered system might exist to regulate or control at least some adaptation. Some creationists have long predicted this.16 And evolutionists are increasingly acknowledging that something like this may exist. Some evolutionists even suggest there is a “mutation-generating system that makes informed guesses about what will be useful” and that such an ability is “plausible, predictable, and validated by experiments”.17 See Box 1.

Clues from immunity

The form such a system could take is not yet understood, but our immune system may give us some clues. The immune system works by intentionally generating a series of random mutations to produce variants from which the right antibody is ‘selected’, which is why evolutionists have at times hailed the immune system as a good example of ‘evolution in action’. (See Box 2, which also demonstrates the functioning of a system designed to generate and control mutations for a specific purpose, strikingly similar to when organisms adapt as described above.)

Limits to adaptation

The existence of any such adaptation system gives little comfort to any idea of amoeba-to-man evolution, ‘God-guided’ or otherwise. Just as the immune system is strictly limited to producing antibody variants (and not brain cell variants, for instance), an adaptation system would likely also have strict limits on the amount of variation that is possible.

The existence of any such adaptation system gives little comfort to any idea of amoeba-to-man evolution, ‘God-guided’ or otherwise.

Like the immune system, it could only do what it was designed to do: generate and control specific changes to already-existing genetic information or body traits.18

Thus, it would be incapable of growing wings on a pig for example (there is no wing-making information present in a pig)—no matter how much time was involved. And as far as present-day observation is concerned, limits to adaptation are indeed what we observe. A recent study titled ‘Evolutionary rescue and the limits of adaptation’, concludes,

“Evidently, there are hard limits to the level of a given stress to which a given organism can adapt … even when some billions of individuals are exposed … for thousands of generations. … [W]e must beware of assuming that [evolution’s] power is unlimited.”19

The immunologist, microbiologist, Darwin skeptic and intelligent design advocate Dr Donald Ewert appropriately notes:

“If we take the data from the immune system at face value, a principle emerges: biological change is orchestrated within limits. The ability to adapt … to changes in the environment while maintaining the integrity of the system is likely a designed feature of organisms.”20

Many of these sorts of findings have stirred great controversy in the scientific community, since blind random mutations and unlimited variation are at the core of neo-Darwinian philosophy. Many evolutionists are struggling with the implications of the data, and some are advocating for a new (or at least ‘extended’) theory of evolution to explain it.12

However, an obvious implication is that any purposeful adaptation system would have been intelligently designed to generate the variety needed for creatures to be able to survive and adapt in this fallen world. Such an ability would be especially useful after the Flood of Noah, and is consistent with biblical creation, not evolution.

Directed mutations

The bacterium E. coli needs a particular amino acid in its food source to thrive. However, when this food source is unavailable, a specific gene in the bacterium gets activated (switched on) which enables the bacterium to survive by producing the amino acid for itself. If this gene were defective, these bacteria couldn’t produce the required amino acid, and without this food source the colony would mostly starve to death.

But scientists have found in the lab that if this gene is faulty or non-functional after activation, the rate of mutation begins to increase significantly in that specific gene location. These mutations continue until the required genetic variation is found which enables the E. coli to begin producing the required amino acid.1,2 This process seems reminiscent of how the immune system operates (targeted, with a specific outcome as a goal).

Similar observations have been found in spiders, snakes and snails “that use poison to capture their prey and defend themselves against predators”. Increased mutation rates specifically targeted to venom genes results in altered venom poison. This enables these animals to adapt to changing environments and to “keep up with changing predators and prey”.1,3,4

The immune system—randomness within plan and purpose

The immune system (IS) in our body is designed to recognize and kill invading germs which cause sickness and disease. Each type of germ has a unique body shape. The IS must produce a specific antibody that fits into the invading germ’s shape, like the correct key in a lock, so it can begin the process of eradicating the invader.

When the IS encounters a particular type of germ for the first time, the way it makes the correct-shaped antibody is by generating a variety of ‘random’ antibody shapes in quick succession, until the correct antibody shape is found which fits into the germ. Multiple copies of this successful antibody are then made.

To do all this, the IS operates a ‘factory’, controlled and protected in a special place within the DNA so as not to interfere with other functions. This factory generates a rapid series of DNA variants, each producing a different-shaped antibody till the correct variant is achieved.

The mechanisms by which these variants arise are the same ones by which animals generate the variation which allows them to change and adapt to their environments—conversion, reshuffling (recombination) and mutation of genes.1 The selection of the ‘successful’ antibody variant is an obvious analogy to natural selection, in which the most ‘successful’ organism gets to make the most copies of its genes. So it’s no surprise that evolutionists often hail the IS as ‘evolution in action’.

But they have missed a critical distinction. The IS produces random mutations intentionally, always within defined parameters and limits, part of a specific response to a given stimulus. Crucially, these mutations are regulated and controlled within a factory that has a clear role and purpose—the hallmarks of a designed system.

Also, there are many potential antibody designs that will do the one-target job (fit the germ), and there is a limited number of options to choose from; that is, it is an easy search. Whereas, with evolution of organisms, many genes are quite specific, meaning that there are a limited number of possibilities that work amongst a huge number of possibilities; that is, it is a very difficult, improbable search.

And as the main text shows, like the immune system, some sort of purposeful system for generating variation ‘as needed’ is increasingly being conceded as likely present in some instances of biological adaptation, too.

Our immune system may therefore reflect, rather than evolution, the way such a designed adaptation system could operate.

I thought of the Shetland ponies that survived--by adapting to their environment. Adaptation is not evolution. These small stocky equines are still horses!

IDvolution - God “breathed” the super language of DNA into the “kinds” in the creative act.

This accounts for the diversity of life we see. The core makeup shared by all living things have the necessary complex information built in that facilitates rapid and responsive adaptation of features and variation while being able to preserve the “kind” that they began as. Life has been created with the creativity built in ready to respond to triggering events.

Since it has been demonstrated that all living organisms on Earth have the same core, it is virtually certain that living organisms have been thought of AT ONCE by the One and the same Creator endowed with the super language we know as DNA that switched on the formation of the various kinds, the cattle, the swimming creatures, the flying creatures, etc.. in a pristine harmonious state and superb adaptability and responsiveness to their environment for the purpose of populating the earth that became subject to the ravages of corruption by the sin of one man (deleterious mutations).

IDvolution considers the latest science and is consistent with the continuous teaching of the Church. [link deleted per feedback rules]

A very helpful article on inbuilt, designed and limited adaptability within kinds, which is likely to help us all in the ongoing controversy with Macro-Evolutionists.

Gary W., United States, 4 January 2017

With mutations unlikely to be the force behind goo to you evolution, some evolutionists are hoping epigenetics (inherited genetic traits) may help their story. But in actuality it's more a case of "Designed to adapt".

A recent study showed mice that were conditioned to fear cherry blossom smell, passed this trait to their offspring. Such examples of inheritance are epigenetic—the expression of genes is affected without an actual DNA change. Due to epigenetic inheritance, the evolutionist argues that evolution has occurred.

Epigenetics involves the switching on or off of already existing genes in response to environmental factors. New genes are not being created in epigenetic inheritance—i.e., no new information is being added to the genome.

William Jeffery of the University of Maryland, conducted the study that discovered cave fish still have their eye genes intact. The eye genes of blind cavefish are still intact, but the expression of those genes appears to be affected by their environment. Their eyesight is merely epigenetically “turned off.” They did not become blind because of genetic mutation.

Epigenetics does not provide the hoped for mechanism for molecules-to-man evolution, which requires the creation of libraries upon libraries of new genetic information. Notice that in epigenetics, like the mouse study example, creatures, through inheritance, are able to pre-adapt to their environments.

Solid evidence for design!

Much of this information came from an article in Apologetics Press by Jeff Miller, Ph.D.

Eddie C., United States, 3 January 2017

Taking this directed adaptation a step further, it suggest that natural selection may in fact be only a natural mishap when the directed adaptation is unable to bridge the gap for all organisms in a population. I am only suggesting it as a hypothesis, but if God did create organisms with the ability to select traits for survival in their environments, to me that would be a more profound and more powerful explanation for variety. This could be true especially for organisms that seem to be perfectly adapted for their environment. Even the loss of information may have been a designed feature. If animals closer to creation had much more potential to adapt and as time went on, animals would become more specialized. The information loss does not have to be specifically because of the sin and man's fall. However, I do realize that entropy exist because of man's fall and that the genome of creatures is degenerating. This is evident in genetic diseases, extinction, and defects we see today.

Another implication of this is there is either a biological system that we do not fully understand or even know about that is directing this change. Could it be an unknown subroutine controlled by an organisms brain that directs the change toward the offspring or is there another selector somehow coded into DNA? I'm just thinking of computer programs that would be able to take information and make selection based on logic driven computer code. Is it possible that DNA has built in logic "IF...THEN...ELSE" code that can direct adaptation? The evidence seems to suggest somewhere that exist, though we might not see the code. How would the evolutionist explain that one?

Joseph M., United Kingdom, 3 January 2017

"...which reflects some of the difficulty in defining information."

Although, we know the fundamental categories this information must have and be adaptable. There are three fundamental categories (probably more). (1) information storage, that is storage of codes, instructions - DNA, etc. (2) information processing, that is error correction, gene expression, etc. (3) information flow, that is cell communication, transportation, etc. in order for the physical appearance or characteristics of the phenotype to emerge e.g. pigs wings.

So for a pig to have wings its not just a gene mutation at the storage level (e.g. duplication) that's required, but also the flow and processing has to be new and all should function together as one i.e. another irreducible complex system.

Once the understanding of the cell was realised, evolution failed and is a dead theory kept alive by a drowning philosophy.
