    What stories? As http://www.historian.net/hxwrite.htm puts it about some
    cave paintings: "As long ago as 25,000-30,000 years BP, humans were
    painting pictures on cave walls. Whether these pictures were telling a
    "story" or represented some type of "spirit house" or ritual exercise is
    not known." I think that represent the consensus of researchers; I have
    myself not seen any old cave paintings that contain any clear story
    element (maybe there is something in Scott McCloud's _Understanding
    Comics_, but I don't have it within reach).

    I think linguists would disagree with you, or rather complicate things.
    There is no syntax for the animal pictures; they might represent things
    and sometimes situations, but their relationships doesn't link together
    in any reliable way. Linguists put special emphasis on the difference
    between finite communication systems and open ended language systems.
    Cave paintings seem unable to express ideas beyond what they depict.

    Of course, we might not know the context. Maybe a bull really was the
    letter 'A', a hunter was an ideogram of 'man' and a negative picture of
    a hand represented the concept of divine foresight, but it does not seem
    likely. As Diamond pointed out, invention of writing is hard and has
    happened only a few times, but once it is done it is easily copied and
    spreads rapidly. The known rapid spread of written languages from a few
    places of origen doesn't seem to fit a world where proto-writing already
    existed but rather a world where it was a quantum jump.

    Yes. And many ritual symbols found in the cave paintings likely led to
    writing. But my point is that writing like other technologies will not
    be likely to flourish outside certain conditions. Agriculture did not
    make people smarter, but it produced a socioeconomic situation where
    writing was useful in many ways, rather than something only possibly the
    tribal shaman sometimes would use. Note that the spread of writing
    systems worldwide occured to agricultural societies; to my knowledge no
    hunter-gatherer societies did use writing until very recently, if at
    all.
