The Stoned Ape Theory of Language

As some Homo Sapiens left the forests for the plains… the species [began] finding magic mushrooms in poop and adding them to the diet… Language development saw immense growth during this period… This is where our minds were opened up to the abstract concepts which eventually led humanity to become the dominant force in the animal kingdom. Our ability to grasp abstract concepts, communicate them, understand what was communicated, and build on those concepts, became the foundation of our civilization.
