My point was that the resistant bacteria didn't suddenly evolve the resistance because the antibiotics were placed in the tray, they were already resistant to begin with. Therefore they didn't "struggle" to become anything, they already had the fit attributes for the situation. Hence why I say survival is a poor word choice as it implies struggle. Death of the non-fit on the other hand, has no such implication. Obviously this is all very black and white edge cases and most of the time we're not talking about absolute death or survival, but decline or success of certain attributes within a given environment. And yes, it probably is a terrible way of phrasing evolution from a PR standpoint ;)
