Just an addendum -- I actually called the RTB web-radio show today and spoke
directly to Fuz Rana about this. He was upfront about the fact that
Templeton's data poses a problem for the RTB model as presented in "Who Was
Adam." He said Templeton's latest paper doesn't differ significantly in
methodology from his earlier "Out of Africa Again and Again" paper;
that Templeton's methodology is the subject of considerable ongoing debate
within the relevant scientific speciality and represents part of the larger
OOA / multiregional fight; and that a large body of data supports some sort
of OOA scenario. All reasonably fair points, I think, though Templeton's
latest run seems to show more robust level of statistical confidence than
his earlier work. He also said it might be possible within his model that
there was indeed a limited amount of hybridization resulting from sinful
liasons between humans and other hominds.
I asked him about the possibility for his model of a genetic connection
arising from God using preexisting hominid DNA to fashion Adam. This was
very interesting, probably the most interesting part of the call -- he said
an earlier draft of "Who Was Adam" contained something like this as a
possibility, but that it was removed by the editors because of concerns that
it would be too controversial for the larger Christian community.
It was a nice conversation and he seems like a sincere and decent guy. I
guess they put MP3's of their web-radio shows on their website, so I suppose
you can download it from there if you want to hear the entire call.
