Could you please provide a link to this acknowledgement?
I ask because there is no mention of VPU on the Edge of Evolution website either as errata or as links to the articles by Ian Musgrave or Abbie Smith or Behe’s responses. Nor does there seem to have been a change to later editions of the book to correct the error. Furthermore, a timeline of the back-and-forth shows that Behe tried to evade admitting his error multiple times.
So while this could be an example of DI members’ integrity, the reluctance to acknowledge a definite error, the lack of corrections, the lack of links to the criticisms and the partial deletion of Behe’s side of the discussion all appear to be evidence of the DI’s lack of integrity.
Added: I did initially say that Behe’s acknowledgements had been deleted. While they don’t seem to be on the main Uncommon Descent website, I found copies here. However, they’re not really an acknowledgement of error, more a continued attempt to avoid doing so and/or keep using the same flawed argument.
