Not sure if these corrections are needed, maybe it was just sloppy wording, but here they are nonetheless:
Depends on why they survived I guess. If they lived because they happened to have particularly thick skulls and managed to pass it on to their children, you could indeed argue that overuse of truck dropping can lead to resistance in the human population.
And even in the real case of bacterial resistance it isn't that they (the individual bacteria)actually become more resistant; they were already resistant and now they have the opportunity to pass on their genes to a much larger fraction of the population, changing the gene ratios significantly. By definition that is evolution.
