Your wider point still stands though, various parts of nature have been putting chemical warfare against each other for a very long time.
We'd best be careful we don't suddenly find ourselves on the wrong side of that battle.
Not really. Antibiotic treatment selects for existing variation within bacteria.
Some bacteria may already be weakly tolerant. Using antibiotics will likely lead to that trait being selected for, and the tolerance becomes stronger.
What have you been studying to get to PhD level as per your prolife info?
You obviously know what you're talking about, and I only have a fairly lay level understand :)
