So? Just because you don't agree does not make it magically become non-evidence - it is just evidence you don't accept. Spin all you want, evidence was presented - you just don't agree with the evidence. BTW: could you state these "rules of evidence" that you are speaking of?
The "rules of evidence" dictate that what is presented as evidence be logically associated with the conclusions it is purported to support. There is no logical association between the Gould's quote and the conclusions Wells has drawn from it. If what he presents as "evidence" does not support his conclusions then it cannot properly be held as evidence.
If we accept your assertion that "evidence is in the eye of the beholder" and I don't see anything he's presented as evidence then you don't have any basis to establish that it is.
