A) too late, B) retraction proves they are not scholars, C) if it's retracted, that makes the peer review process at PNAS worthless.

[aposiopetic]

In the old days, to get published in PNAS you had to "know somebody," meaning you had to have a connection to a member of the NAS, who could submit the paper.

Ergo, I'm not sure how good the PNAS review process ever was, though it's a shame this paper is being pulled if it's accurate.
