We know that evolution is optimizing for continuation or duration (technically "evolution" isn't a thing, it's a non-volitional chemical tautology with no purpose or intrinsic meaning so "it" cannot optimize, however, in practice, life is optimizing for more and continued life, overcoming radiation, impacts, and it's own consequences (like the advent of oxygen and aerobic metabolism)) so what is the other system optimizing for?

(As an aside, is "life is optimizing for more and continued life" a definition for "life"?)
