I see what you're saying and it's a good point, but those complex interactions seem to throw up impossibly amazing stuff, for example the utterly mindblowing idea of mitochondria being captured organisms. To say "it's complex so surprises should be surprising" to me just doesn't make work. I still get staggered by this stuff. If I ever lose the ability to be mindblown, it'll be a sorry day. Fungi in the pancreas isn't in the same league but it's still pretty good!
