I’m srry, but bacteria dying and then having the few remaining end up being resistant isn’t “evolution”.
It’s still the same bacteria, it’s just had all it’s other traits knocked out of the gene pool. Congrats, you’ve just narrowed the natural genetic potential of a species.
Taking a flu vaccine- for one, is a virus alive? For another, all you end up doing is restricting the most recent population. It’s still the flu. No evolution, just more pigeon-holing.
When the bacteria that keep becoming resistant to our drugs changes into a completely new species (one not formally present in it’s host culture) we’ll start talking about bacteria evolving.
Are you so completely ignorant that you don't know that evolution studies on bacteria start with a single cell?
This is factually incorrect. Studies of bacterial adaptation start with a single cell. Any adaptation occurs as a result of mutation.
What do you have in mind when you refer to bacterial species?
