I'm sure this is an extremely elementary question, but I've wondered this most of my life. How is it that, say, ponds with no connection to larger greater water systems tend to have the same ecosystems as other ponds? Around here, catfish tend to be populated in most ponds even if they are not necessarily stocked for fishing purposes. Is this just how convergent evolution tends to work?
Oh, and since I'm not really in the mood for trolling, I will ask that Omniskeptical not post in this thread.
