What Are Alleles? 🧬
Alleles are different versions of the same gene.
For example:
- If one copy of a gene codes for black eye color, and another copy codes for blue eyes — both are alleles of that same gene.
HLA genes — part of the immune system — are among the most diverse in the human genome. Evolutionists use this diversity to argue that modern humans must have originated from a large ancestral population — not just two individuals.
The Claim: HLA Diversity Requires Large Populations 📈
A famous Darwinist study claimed that HLA gene diversity requires at least 32 primary alleles, which, according to their model, could not exist in a population smaller than 4,000 individuals, and possibly even 100,000.
They conclude:
❌ “Diversification from only two people is impossible.”
✅ “Humans must have evolved from a large population.”
But where do these numbers come from?
👉 From evolutionary assumptions about mutation rates, divergence times, and selection pressures — all based on the human-chimpanzee split timeline.
And here lies the problem…
Their Assumptions Are Built on Evolutionary Bias 🧨
The calculations depend heavily on:
- Mutation rates assumed over millions of years.
- Evolutionary trees that contradict each other.
- Molecular clocks that change depending on what story they want to tell.
In short:
🔸 When they want to reject small populations, mutation rates mysteriously slow down.
🔸 When faced with contradictory data, they invoke convergent evolution, parallel evolution, or genetic drift — without explaining how such complex systems could arise independently multiple times.
This is selective science, not objective truth.
Blow #1: A Small Bottleneck Is Scientifically Validated 🧪
A peer-reviewed evolutionary study published in Science analyzed over 3,154 human genomes and found:
“…a severe population bottleneck with about 1,280 breeding individuals between around 930,000 and 813,000 years ago. The bottleneck lasted for about 117,000 years.”
https://www.science.org/doi/10.1126/science.abq7487
Why did the population stay stable for so long without going extinct?
And if such a small number survived for over 100,000 years, why can’t we consider a more recent bottleneck of two?
Even Nature described this as a 99% loss of the living population.

Blow #2: HLA Gene Patterns Contradict Evolutionary Trees 🧬🧱
Another study in ScienceDirect showed that when comparing HLA-DRB sequences across humans, chimpanzees, and macaques, the relationships were inconsistent and species-specific.
“Most of the primate DRB alleles investigated represent relatively young entities, possessing species-unique sequences.”
“As no evidence was found for convergent evolution, the combination of these two observations indicates that ancient peptide binding motifs are frequently reshuffled among duplicated members of the HLA-DRB multigene family.”
https://www.sciencedirect.com/science/article/abs/pii/S0161589008000722
The supposed ancient origins of these alleles don’t hold up.
There’s no evidence they were inherited from a common ancestor.
Instead, they appear newly generated within each species.
This undermines the argument that HLA diversity proves an ancient, large human population.
Blow #3: Convergent Evolution ≠ Explanation 🙅♂️🚫
But this isn’t a scientific explanation — it’s a label used when evolutionists run out of answers.
“An application of the method to HLA protein sequences suggests that intragenic recombination played important roles in HLA-B and DPB1, some in HLA-A and DRB1, and least in HLA-C and DQB1 diversity. However, the extent of diversity of these molecules does not necessarily correlate with the frequency of intragenic recombination, supporting the view that (balancing) selection is a primary agent of HLA diversity and often leads to convergent evolution.”

Selective storytelling wins again.
Blow #4: Bottlenecks Don’t Eliminate Genetic Diversity 🧬🪶
Another study looked at white-tailed eagles that went through a severe population bottleneck — yet retained significant genetic diversity.
“Despite passing through demographic bottlenecks, white-tailed eagle populations have retained significant levels of genetic diversity.”
“Migration between populations has not been a major factor for the maintenance of genetic variability.”
https://royalsocietypublishing.org/doi/10.1098/rsbl.2006.0453
If a wild animal species can retain high genetic diversity after near extinction — then why not humans?
Final Blow: Models Show Diversification from Two Is Possible ✅
Several models have shown that starting from just two individuals, the current level of human genetic diversity can be achieved — especially with realistic mutation rates and reasonable timeframes.
- The Discovery Institute modeled human genetic diversity and found that a single pair (~500,000 years ago) explains current variation better than multi-pair models.
https://bio-complexity.org/ojs/index.php/main/article/view/BIO-C.2016.3
- Even evolutionary simulations have shown that a bottleneck from a single pair could generate today’s diversity — assuming the standard human-chimpanzee split timeframe.
https://discourse.peacefulscience.org/t/heliocentric-certainty-against-a-bottleneck-of-two/61/12
So if even evolutionary scientists can simulate genetic diversity from a pair — why is the idea of two ancestors dismissed as unscientific?
Addressing the Objection: Inbreeding Causes Extinction ❌
One final objection:
“Mating in a limited population leads to diseases and eventual extinction due to inbreeding.”
Our response:
We are not claiming that Adam and Eve carried the diseases we see today. Diseases increase over time due to genetic entropy — the accumulation of mutations in DNA.
- All organisms were originally created with functional, error-resistant genes.
- Over generations, mutations accumulate, leading to disease, defects, and reduced fitness.
- This is consistent with the concept of genetic decay, not evolution.
Think of it like software updates:
📱 Later versions have more features — but also more errors.
🧠 That doesn’t mean later versions are better — just newer.
Because variation allows for adaptation — within limits — and serves a purpose in design.
Conclusion: Evolutionary Math Doesn’t Disprove a Genetic Bottleneck 🧮💥
The argument that HLA gene diversity disproves a human origin from two is built on:
- Evolutionary timelines
- Shifting mutation rates
- Circular reasoning
- Selective acceptance of small populations
- And magical labels like “convergent evolution”
Real studies show that small populations can maintain diversity.
Simulations support diversification from two individuals.
Observed genetic patterns do not require millions of years or thousands of ancestors.
Therefore, the claim that science has proven the impossibility of diversification from two pairs is false — and built on biased assumptions, not objective facts.
