8.3 “The Experiment Assumes Evolution in a Single Step”
When attacking a caricature — and ignoring what was actually tested
Objection
Some critics claim that Douglas Axe made a fundamental error in his 2004 study: he supposedly assumed that the evolution of complex systems happens in a single leap — as if a functional protein needed to emerge fully formed all at once. They argue that, in reality, evolution works through small, gradual steps, with intermediate forms that may have partial or different functions before reaching the final function.
🪜 For the lay reader: It is like saying we don't need to find a whole needle at once — we can find little pieces of it gradually. But Axe showed that even finding a single functional piece of the needle requires searching more haystacks than exist in the universe. And worse: these pieces only work if found together and perfectly fitted.
What Axe Actually Did
Axe did not ignore the idea of gradual evolution — he tested it directly. On page 1309 of the article published in the Journal of Molecular Biology, he explicitly discusses this possibility:
✅ Accessible methodological summary:
- Axe did not assume evolution occurs in a single leap
- He investigated whether gradual paths between functional sequences are truly accessible
- And discovered that even the shortest paths require too many coordinated changes to be feasible
🪜 Integrated analogy:
Where is the Logical Error?
The criticism commits the straw man fallacy — attributing to Axe a position he never defended, only to refute it. Axe did not say evolution must happen in a single leap. He asked:
🪜 Explanation for laypeople: It is like trying to assemble a 1,000-piece puzzle without knowing the final image, without knowing where the right pieces are, and without enough time to test all combinations. Even if you try to assemble it gradually, the chance of success remains absurdly small.
What the Data Show
Let's consider the most optimistic scenario possible for evolution:
- Global bacterial population: 10³⁰ cells
- Mutation rate: 10⁻⁹ per gene per generation
- Evolutionary time: 10¹² generations
Multiplying everything:
Now compare with the probability Axe found for the emergence of a functional protein:
🪜 Visual explanation: It is like having 10³³ lottery tickets — but needing 10¹⁵⁰ to have a real chance of winning. Even if you play every day, with all possible tickets, you don't even come close.
Model
Even if we needed only 5 coordinated mutations simultaneously — an extremely optimistic scenario — the probability would still be less than:
And even if we consider the entire universe as a supercomputer, with:
- Time since the Big Bang: 10¹⁷ seconds
- Atoms in the universe: 10⁸⁰
- Operations per second per atom: 10¹⁵
Total possible operations:
Still, it doesn't even come close to the 10¹⁵⁰ needed.
🪜 For the lay reader: It is like trying to find a specific needle in a universe full of haystacks — and needing to find several pieces of the needle at the same time, which fit perfectly. And there aren't enough haystacks even in the entire universe.
What Does the Scientific Literature Say?
- Wolf-Ekkehard (2009): Shows that even two coordinated mutations require waiting time greater than the age of the Earth
- Lynch (2020): Admits that real populations are too small to accumulate multiple beneficial mutations
- Durrett & Schmidt (2008): Demonstrate mathematically that gradual evolution does not have enough time to work, even in fast-reproducing organisms
🪜 For the lay reader: These studies were not made by intelligent design advocates — they were made by evolutionists who recognize that the numbers don't add up.
Why This Criticism Fails
The criticism fails because it attacks a position Axe never defended — and ignores the calculations he actually made. Axe did not say evolution must happen in a single leap. He asked:
And the answer, according to the data, is: no.
🪜 Final analogy:
Conclusion for the Lay Reader
Douglas Axe did not ignore gradual evolution — he tested it with real numbers, under generous conditions.
The criticism makes a basic error: attacking a caricature of the study, not what was actually done.
🪜 Visual summary:
Therefore, this criticism does not invalidate the study.
