    Isn't the human body a perfect example as there are many times more bacteria living in/on us than we have human cells. Not to mention the fungi and other types of guests. And for the most part, we all (all species involved) benefit from the relationship. I'm sure we've evolved together to reach this point.

      on all the things that live in them and on them and in their houses.  The relationships between ourselves and the organisms inside us are pretty variable.  Some are definitely mutualisms (getting turista is usually the result of getting E. coli or another intestinal bacterium from a population that has not co-evolved with you).  Others may be pretty neutral from our perspective and some are definitely predators (at the microscopic level).  One thing to remember is that in your lifetime the bacteria in your gut will have undergone over 10,000 generations worth of evolution.
