Personally I think this has happened a lot more than people want to admit/give credit to.
For instance I was taught that that the Europeans created (block) printing around 1400, igniting the religious reformation, blah, blah, blah. There was no mention that Asia/China had already been making block prints for more than a thousand years.
Semi recently I heard (on NPR I think) an anthropologist theorized that things like our modern ideas of independence, individualism, voting and our system of government can be traced back to concepts already in practice by the indigenous peoples of the Americas. And even went on to blame the French (sailors) for bringing those ideas back to Europe - spurning on the Age of Enlightenment and inciting both the French and American Revolutions.
And no, I don't have any citations for this, just my (faulty) recollections of a radio conversation while on the road.
Try not to get discouraged, message boards (or at least the Pub) doesn't tend to get rapid Social Media like responses - especially as the days get long and we head into Pirate Event Season. I for one actually appreciate your' inquiries.
