The driving force behind evolution is mistakes and repetition. Almost perfect copies again and again, with room to breathe and room to expand. When something, when anything, goes horribly wrong and there is sufficient variation... there will be survivors. The number one rule is to survive. That doesn't mean knowing what will happen. It means knowing something will happen. Plans only help for the things you understand, resilience helps for the things you don't. With humans came consciousness. With communication came shared consciousness. We can now make plans and try bend the world to our will, but we should keep that humility. The humility that comes with knowing that we don't know.
