Maybe the poster who started the thread might have info., but I don't know about the 700.
HOWEVER, here are 400 scientists with their institutions, etc.

Here are over 400 scientists, and their credentials who are skepitcal and say "Careful examination of the evidence for Darwinian theory should be examined.":

Now as an aside, the ACLU in Dover is suing a school board for simply reading a 4 paragraph statement to the students saying that there is another theory, Intelligent Design. The ACLU censors any HINT of God whenever they can.
Firstly that list of 400 is not mostly biologists. Secondly the exact statement that they signed up to is one that any scientist could say about any scientific theory. Thirdly it is possible to doubt natural selection as the sole mechanism for evolution without doubting for example common descent. Now, have you got that delegate list, given the poverty of the 400 so far I'd be really interested in seeing who went to the prague conference.
