I have been getting a number of links to articles on this recently. I think it is fascinating, but also important to not jump the gun, so to speak. The popular press seems to be presenting this as if it overturns the 2010 hybridization results (they love a good headline!).
As I understand it this paper was presented at a meeting a year ago, at the same time one or two other papers supporting the hybridization were also presented but are not yet published. Reichs, one of the author of the 2010 paper, is publishing another analysis that apparently falsifies the Erisson & Manica model (and supports hybridization). I also heard that a second paper is also in the pipeline by another researcher who used a completely different analysis to support hybridization.
Anyhow, point is that there are some really fun times ahead for those of us on the sidelines with an interest in this kind of stuff!
