How can things become stabile? This is a difficult question to answer, but we should nevertheless try, because of the answer´s importance for life, for us.
Admittedly the question sounds too broad to try to find an answer, but largely this is because we tried to find a universal answer, a universal answer instead of an evolutionary one. The large advantage of the evolutionary view is that reductionism is “only” needed to find the possible base for a phenomenon which is analyzed and which could as well be a relatively modern phenomenon and afterwards from this base ideas can be developed further; relatively modern refers to modern estimated from the duration the phenomenon influences developmental and evolutionary processes compared to the total duration of the evolutionary process on Earth.
