All this information really does is deepen the mystery about the self awareness of mankind and how in such little progression there was over such a long period of time.
Still the same problem as it ever was. Information transmission within pre-literate hunter/gatherer clans isn't really all that good if you're hoping to join the space race any time soon. I still want to thank the person who figured out that those leaves thrown in hot water tasted good. That's some long term trial and error testing going on, and not a trial I'd want to take part in.
