A large number of species in the world effectively rely on symbiosis.

My point was that at what level of symbiosis do multiple organisms become a
single organism? It is easy to conceive of symbiotic organisms that
co-evolved to the point where they really couldn't survive without the
other. But even in cases of very close symbiosis, there are still two
distinct organisms -- you can kill one without killing the other. There is
a fuzzy point where the boundary isn't clear, but human societies don't
have any such fuzzy boundaries between individuals.
