Fascinating! Especially the part where the paleoentologists and archeologists conjecture that music provided the long term advantage the Cro-Magnons had over the Neandrethals. Sounds like this study was sponsored by your local symphony orchestra!
I especially found this statement amusing:
Music could have played a role in the maintenance of larger social networks, which may have helped our species expand their territory at the expense of the more conservative Neanderthals.
This sounds like something Public Radio would put out.
I think he might have reconstructed it because it was in perfect pitch when he played "America the Beautiful."
