I find this story very interesting because we've always been taught that the 'New World' was an Eden full of happy harmonious people that the white man destroyed when he brought over horrible diseases and greed for natural resources. We're all supposed to have a national culture of guilt and shame over this.
The scientific community probably won't give these researchers the time of day. If they did research to "prove" that the white man was even more horrible and destructive than previously thought, they'd give them Nobel prizes.
Hanta virus, however, can kill millions of people in short order and leave civilizations destroyed in its wake.
