The microevolution misunderstanding that misleads both sides of the debate — and the question evolutionists avoid answering.
A minister once asked me, with complete sincerity: "Do creationists really refuse to accept any change in species at all?" I was stunned — not by the question's boldness, but by what it revealed about how profoundly creationist science is misunderstood, even within the Church.
This article is an attempt to correct that misunderstanding precisely, and then push the conversation to where it actually matters: the question of information.
Famous creationist debaters emphasize in nearly every debate that they accept microevolution. Reputable creationist websites publish extensive articles on the topic. And yet the public image of creationists remains that of a group who deny any biological change whatsoever.
Let's be direct: creationists fully accept that species change, diversify, and adapt within limits. Different dog breeds, wolf varieties, the diverse species of the cat family — creationists believe these all descend from common ancestors through genetic variation. This is observable science, and no serious creationist denies it.
A personal note: I actually dislike the term "microevolution," because the word evolution implies upward progress or information gain — and what we observe in microevolution is neither. But since the term is universally understood, we'll use it throughout this article.
Modern biology organizes life into a hierarchy: Kingdom → Phylum → Class → Order → Family → Genus → Species. But the Bible doesn't follow this scheme. Instead, it speaks of God creating living things according to their kinds:
Where do these biblical "kinds" fit in the modern taxonomy? Because modern classification is imperfect and partly arbitrary, we can't draw an exact line. But most creation scientists estimate that the biblical kind corresponds roughly to the Family or Genus level. The species below that level are understood to have diversified through variation.
Most creation scientists place the biblical "kind" at roughly the Family or Genus level of modern taxonomy. Species-level diversity arose through variation from these original created kinds.
This means creationists don't believe God separately created every wolf species, every dog breed, and every coyote. Instead, He created the dog kind — an ancestor that carried rich genetic potential — and the variety we see today emerged through variation, isolation, and selection.
The mechanism behind this diversification is simpler than most people assume — and critically, it requires no new genetic information whatsoever.
Consider a simple model. An organism carries gene pairs we'll represent as Aa Bb Cc (capital = dominant variant, lowercase = recessive). When two parents who each carry Aa Bb Cc reproduce, their offspring can inherit any combination of these variants.
| Parents | Possible Offspring | Information Change | Implication |
|---|---|---|---|
| Aa Bb Cc × Aa Bb Cc | AA BB CC | Net Loss | Lost recessive variants a, b, c |
| Aa Bb Cc × Aa Bb Cc | aa bb cc | Net Loss | Lost dominant variants A, B, C |
| Aa Bb Cc × Aa Bb Cc | Aa Bb Cc | No Change | Full range preserved |
| AA BB CC × AA BB CC | AA BB CC only | Locked | Can never produce a, b, c variants again |
This is the key insight. When a population carrying rich genetic diversity splits and breeds in isolation, it differentiates — but in doing so, it also loses the ability to produce certain variants. The gene pool narrows. Diversity appears at the species level, but information is lost at the genetic level.
When an original kind splits into isolated populations, genetic information is sorted and reduced — producing visibly different species, but with a narrower gene pool than the common ancestor.
This is how creation scientists understand the diversification that followed Noah's Flood. The animals that exited the Ark carried diverse genetic information. As they dispersed into different environments and populations separated, that information sorted and narrowed — producing the array of species we observe today.
So if creationists accept species diversification, where exactly is the disagreement? Here is where the conversation must become more precise.
A common argument from evolutionary bloggers and popularizers runs like this: Evolution simply means an increase in diversity. A bird with wings and a bird without wings (due to mutation) now gives us two types — therefore, evolution has occurred!
Creationists do not dispute that this phenomenon occurs. A wingless variant arising from a winged population is real and observable. But notice what actually happened: genetic information was lost, not gained. The wing-building instruction set was deleted or disabled. The result is two populations, yes — but the total information in the gene pool has decreased.
Taking the Bible, splitting it into the Old and New Testaments — now you have two books! Or mixing Bible and Quran verses to produce a new religion. Diversity has increased.
How did the Bible and the Quran get written in the first place? No amount of rearranging existing text explains the origin of the original text.
Evolutionary theory, creationists argue, is very good at explaining how existing information can be rearranged, combined, or reduced to produce variety. But it has no mechanism — theoretical or observed — for generating the kind of new, meaningful information required to go from a single-celled organism to a human being.
This is the crux of the creationist critique — and the point that, in creationist debaters' experience, evolutionists consistently sidestep.
"Every mutation studied at the molecular level has caused a loss of information, never a gain... A business that continually loses money cannot become profitable simply by losing money more often. Every loss of information, no matter how small, cannot contribute to the kind of evolution neo-Darwinism requires... Not a single mutation has been observed that increases the information in the genome."— Lee Spetner, Ph.D. (Physics, MIT) | Research Physicist, Johns Hopkins Applied Physics Laboratory | Not by Chance, 1997
"Mutations only cause changes in existing information. There can be no increase in information, and in general the results are harmful. Blueprints for new functions or new organs can never arise. Mutations are not a source of new (creative) information."— Werner Gitt, Ph.D. | Director of Information Technology, German Federal Institute of Physics and Technology (PTB) | In the Beginning Was Information, 1997
Think of the genome as a software program — the most complex program ever discovered, running on molecular hardware. The creationist argument is not mystical or religious at this point; it is a claim about information theory.
Meaningful, functional information — whether in software, a novel, or a genome — does not arise from random processes. We have never observed it. We have never produced a theoretical mechanism for it. And when information in a genome changes via mutation, the change is virtually always a degradation or loss.
Neo-Darwinian theory claims that random mutations, filtered by natural selection over billions of years, produced all of that additional information. Creationists point out that this claim has never been observed, never been replicated experimentally, and is contradicted by information theory: you cannot accumulate information through processes that consistently destroy or rearrange it.
A common argument for evolution is that microevolution, given enough time, will produce macroevolution. But this reasoning fails at a fundamental level.
Every example of microevolution we observe involves one of two things:
This is precisely Spetner's financial analogy: a business that loses a small amount of money each quarter does not become profitable by losing money for long enough. The direction of information change matters — and every observed mutation moves in the wrong direction for macroevolution.
Even this illustration vastly understates the improbability. Human genome complexity makes the coin-flip scenario look trivially easy by comparison.
Even the broader scientific community has recognized that traditional evolutionary theory faces serious explanatory challenges. A landmark 2014 Nature commentary asked whether evolutionary theory itself needed a fundamental rethink — with biologists who accept evolution acknowledging that the current mechanisms are insufficient to explain observed biological complexity.3
Yet even when creationists raise the information problem, the standard evolutionist response is to continue pointing at diversity — at microevolutionary change — as if accumulating enough examples of information loss will eventually produce information gain. It won't. The direction matters.
Let's put the two positions side by side clearly:
| Question | Creationist Position | Evolutionary Position |
|---|---|---|
| Do species change over time? | ✅ Yes — within created kinds | ✅ Yes — at all levels |
| Is this change observable? | ✅ Yes — microevolution is observed and predicted | ✅ Yes |
| Does mutation add new information? | ❌ No — mutations lose or rearrange information | ✅ Claimed — but not observed |
| Can microevolution scale to macroevolution? | ❌ No — wrong direction of information change | ✅ Claimed — with enough time |
| Where did original information come from? | From an intelligent Creator | Unresolved / naturalistic mechanisms |
Creationists don't deny that species change. They deny that random, undirected processes can write the information that makes life possible in the first place. Observable science supports the former. The latter remains a theoretical claim with no observed mechanism.
The genome is the most information-dense structure ever discovered by science. Every program has a programmer. Every code has a coder. Believing that the most complex code in the known universe wrote itself through random noise is not the scientific default position — it is a philosophical commitment dressed in the language of science.
