Interesting read. Though my comment is on a benign technical detail. There were links in the article to other articles that I expected to work given how recently the article was published. For example, I was interested in reading about the 40k year old flutes - http://www.nytimes.com/2012/05/29/science/oldest-%20musical-instruments-are-even-older-than-first-thought.html http://www.nytimes.com/2012/05/29/science/oldest-%20musical-... Curious that the link would appear at all. I'd think there would be constraints on this during publication?
