Refuting the claim that bacterial resistance is evidence of evolution

Antibiotic Resistance in Bacteria: Is It Evidence of Evolution?

There are many types of bacteria that have undergone genetic changes, making them more resistant to antibiotics and thus more deadly to humans. Some claim that understanding how evolution leads to increased bacterial resistance is crucial in limiting the spread of infectious diseases. But what does "evolution" have to do with this? What role do random mutations and blind selection play in the mechanisms that have astonished scientists themselves, leading them to describe bacteria as intelligent and to use terms like "science" and "will"?

The Complexity of Resistance Mechanisms: The Beta-Lactamase Enzyme as a Case Study

Let’s take, for example, bacteria’s ability to resist the first known antibiotic, penicillin. They have achieved this through numerous, highly complex and precise mechanisms. One such mechanism is the production of the beta-lactamase enzyme.

This enzyme consists of hundreds of amino acids arranged in a precise sequence with no room for randomness. In the final stages of its production, specific modifications occur at highly targeted locations, allowing the enzyme to fold into a three-dimensional structure. Its sole purpose is to target the weakest point of the antibiotic, neutralizing its effect.

Where is the randomness and chance in all of this? One scientific paper discusses a type of beta-lactamase composed of 263 amino acids. Have you ever seen bacteria making random, failed attempts to assemble chains of varying lengths (50, 100, 200, 300) with random arrangements, only by chance arriving at this precise enzyme? If left to randomness, the earth, sea, and sky would be filled with failed attempts before this enzyme could ever emerge.

Microscopic Intelligence or Random Evolution?

When researchers develop a new antibiotic to counter this enzyme, bacteria respond by producing another type of beta-lactamase, then a third, fourth, and fifth—so much so that one might think they are dealing with an organism that has massive research and development centers rather than microscopic creatures that multiply by the millions on a pinhead. This is just one of the many resistance mechanisms bacteria employ. So, what does this have to do with randomness?

Testimonies from Nobel Prize-Winning Scientists

Several prominent figures in the field of antibiotics have expressed discomfort with the inclusion of "evolutionary theory" in the narrative of discoveries in this area:

1. Dr. Ernst Chain, one of the three scientists who produced penicillin and a Nobel laureate alongside Alexander Fleming and Howard Florey, described the myth of random mutations as a hypothesis unsupported by any evidence. He found it incompatible with facts and marveled at scientists accepting it without scrutiny.
2. Dr. Selman Waksman, the discoverer of streptomycin—the first effective antibiotic for tuberculosis—and another Nobel laureate, described the application of Darwinian principles to the struggle for survival in the world of antibiotics as "a figment of the imagination."
3. Professor Philip Skell, who contributed to the development of antibiotics and is described as the "father of carbine chemistry," wrote an article in 2005 for The Scientist titled "Why Do We Torment Darwin?" In it, he stated:

   "There is no doubt that my own research on antibiotics during World War II was not guided by Darwinian evolution, nor was Alexander Fleming’s discovery of penicillin’s inhibition of bacteria."

Evolution as a "Literary Glitter" Rather Than Scientific Guidance

Professor Skell noted that he asked over 70 prominent scientists whether they would have conducted their work differently if they believed Darwin’s theory to be false. All responded with a resounding "no."

Skell argued that Darwinian theory did not provide tangible guidance in major biological discoveries. Instead, it was retroactively imposed as a "literary glitter" to draw attention, much like bringing in a dignitary to cut a ribbon after a project is already completed.

Skell was bold in his criticism and responded to the National Academy of Sciences with an article warning against the "unnecessary and misleading insertion of speculative historical and philosophical ideas into the realms of experimental science." Naturally, he faced backlash from supporters of the theory, who subjected him to abusive language due to his scientific stance.
