Is There Any Ego in Nature?

Every sufficiently complex organism needs to develop some sort of ego. If something is in existence, and it keeps existing for any significant length of time, then it has to develop a system to maintain its integrity. Otherwise what happens is that either the thing will crumble and collapse and dissolve entirely - which we might call death. Or it will morf and evolve to such a degree that you won't be able to recognize it any more. That's what i mean by ego. We're talking about how life is constructed at all. Right? And i'm not just talking about biological life. I'm talking about any complicated system. Even religion is like an organism. It's alive in a certain sense
