Darwinism, Labor, Marxism

As has been previously discussed, Marxism and Darwinism intersect in the concept of Species-Being.  They also do so in the concept of tool-abetted Labor as the fundamental fact, according to Marxism, of human existence.  For, the use of virtually all tools is in one respect or another impossible without opposing thumbs, which, according to Darwinism, is the product of an evolutionary process.  Thus, insofar as Human history is constituted by relations of Production, it is determined by a principle of Evolution, as is, therefore, both the emergence and the fate of Socialism.
