Natural Selection, Theory, Practice

Marx-Engels express admiration for Darwinism despite the fact that it intreprets the world, rather than seeks to change it, unlike, say, a Practical correlate of the theory of Natural Selection.  But, even in the case of Artificial Selection, i. e. of selective breeding, engendered improvements are hardly of the epochal scope of the survival of the Species, or even that of the elimination of exploitation from Human society.  Instead, one lesson for Marxism, from either Natural or Artificial Selection, is the randomness of Nature, which calls into question the presumption of Necessity in Dialectical Materialism, and perhaps reminds Marx that his reduction of Epicurus' Swerve to that neo-Hegelian scheme suppresses that randomness.
