This is the 19th of 23 presentations in a series introducing and outlining my hypertext book project, "Application Holy Wars or a New Reformation - A Fugue on the Theory of Knowledge". The project explores the interactions of technology and cognition in the extraordinary evolutionary history of the human species. This presentation discusses how the mastery of fire greatly expanded the ecological niche that could be occupied by the carnivorous apes that became us. This also meant that proto-humans had to remember and share larger and more detailed volumes of knowledge about technologies and natural history than had ever been required previously - establishing selection pressures for the cultural construction, sharing and transmission of knowledge. Before the capacity for linguistic communication was established it is likely that enhanced social behaviors around the campfires such as directed attention, dancing, mime and singing helped with activities such as organizing hunts and sharing critical survival knowledge. Language would have to be evolved before the details of complex technologies required for making things like effective hunting bows and arrows with hafted heads could be reliably transmitted. Fire and language gave Homo heidelbergensis the capacity to expand throughout Africa and across Eurasia. A later wave of even more sophisticated Homo sapiens again expanded out of Africa to replace all of the older relations. Arguably, this success was was founded on technological superiority and better systems for managing and sharing knowledge.
