Humanism, Biology, Evolutionism

As has been previously discussed, Marx proposes that it is the manufacturing and use of tools that is the defining characteristic of the Human species.  But, that capacity is impossible without unique Biological traits such as flexible opposable thumbs that can grip and manipulate tools. Still, since it is not inconsistent with Genesis 1, Comparative Biology does not decisively ground Humanism.  Rather, that is accomplished by Evolutionism, which proposes an origin of the species to counter the familiar account of Supernaturalism. Thus, Humanism does not complete the liberation from Medieval Theocratism until the arrival of Darwinism.
