Quick, Nurse, Give the Patient a Tautology!

Is Darwinism essential to understanding bacterial resistance to antibiotics? Consider the following conversation, at the bedside of a patient with a serious antibiotic-resistant infection:
Nurse: Nothing’s working, Doctor!
Doctor: I know. All of our antibiotics have failed. Penicillin, Cipro, Tetracycline. Nothing is working.
Nurse: Let’s ask the Darwinists for help!
Doctor: (Slaps forehead) Of course! Darwinism is the foundation of our understanding of bacterial resistance to antibiotics. Quick, Nurse, give the patient a tautology!
Darwinists claim that Darwin’s theory, which is the theory that all biological complexity arose by random variation and natural selection, is essential to our understanding of bacterial resistance to antibiotics. What exactly does Darwinism teach us about antibiotic resistance?

Microbiology tells us that bacterial populations are heterogeneous. Individual bacteria differ from one another. Molecular biology tells us that some bacteria have molecular mechanisms by which they can survive antibiotics. Molecular genetics tells us how these resistance mechanisms are passed to other bacteria and through generations of bacteria. Pharmacology helps us design new antibiotics that circumvent the bacterial defenses.
What does Darwinism add to the sciences of microbiology, molecular biology, molecular genetics, and pharmacology? Darwinism tells us that antibiotic-resistant bacteria survive exposure to antibiotics because of natural selection. That is, bacteria survive antibiotics that they’r e not sensitive to, so non-killed bacteria will eventually outnumber killed bacteria. That’s it.
Microbiology, molecular biology, molecular genetics and pharmacology are indispensable to modern medicine. We’ve learned much about intricate bacterial defenses against antibiotics, and we’ve developed hundreds of antibiotics that have saved millions of lives. What has Darwinism added to these miracles? Just this: non-killed bacterial eventually outnumber killed bacteria.
Darwinism is worthless to modern medicine. That’s becoming a tautology, too.
