This papers aims to realize a philosophical-scientific analysis of the “extinction” problem and, in particular, the «sixth mass extinction». For such, and considering recent paleontological and biological data, we will discuss its scientific realism and epistemic accuracy. We will also have in consideration its theoretical and philosophical vectors, namely the influence of the Nietzschean pre-eugenic (Galtonean) ideology. We will conclude contemporary scientific extinctionism as (still) a philosophical «wishful thinking» which can, although, be achieved through the occurrence of certain phenomena involving human agents than a synergic convulsion properly saying.
