Will to Power, Will to Live, Evolution

In #349 of The Gay Science, written after Thus Spoke Zarathustra, Nietzsche characterizes "the wish to preserve oneself" as a "symptom of distress, of a limitation of the really fundamental instinct of life which aims at the expansion of power."  In other words, the Will to Live is a special case of the Will to Power, in the same way that Velocity is a special case of Acceleration.  He proceeds to deride Darwinism as a "doctrine of the 'struggle for existence'", without considering one of the significant implications of that classification.  For, since the pattern of the Evolutionary process is Self-Overcoming, Evolution correlates to the Will to Power.  Thus, Nietzsche here identifies a fundamental internal flaw in Darwinism--its subordination of the Will to Power to the Will to Live, which is logically impossible, since the latter is derived from the former.  In other words, Darwin cannot posit the existence of Evolution without concomitantly establishing it as a principle that supersedes the Survival principle.  Likewise, attempts among Evolutionists to derive the former from the latter, e. g. 'Emergent' theories, are fundamentally misguided.
