the mark as "oral" and "writing" traditions

last class, I made the point that oral traditions precede writing by a long shot. the mark above is an example of proto-writing. 

how far back? 

these signs (used next to images of animals), may have appeared as early as the Upper Palaeolithic in Europe circa 35,000 BCE. it's the earliest form of proto-writing, see the dots, used in combination perhaps to convey seasonal behavioral information about hunted animals. 

this is pre-civilization. 

now, all this is hypothetical.

scholars make a distinction between "prehistory and "history" of early writing. and what would that be? writing! what some call "true writing".and what's that. there's disagreement. 

writing means recording information as graphemes, which may, in turn, be composed of glyphs. 

what's the distinction?
