ok, then you can test this yourself I believe. I saw an experiment a while back involving bacteria and petri dishes. the idea behind it was that the petri dish, if made a livable area for the bacteria, will allow for ones that would be more specialized to it to survive better and this reproduce more. I'm sure you could find a description better then the one I've given, but hey I'm doing something at the moment.
