Selection is the ability of an object to survive in its environment, but it also requires the object to be continuously destroyed and made through a process and over time. For selection to be truly interesting, there needs to be a turnover in time, with objects continually created and discovered. If an object, like a molecule, can act on itself or cause a chain of events to bolster its formation, it goes from discovery time to production time, resulting in more of it in the universe.
