That list is notorious for being dishonestly put together, there are people on that list who have stated that they do not support the Discovery Institute and were misled about what they were signing. It also has people who are not professionally qualified to be signing as a "scientist" in the first place.
It's what people have come to expect from the Discovery Institute though, honesty and truth are less important than getting their political agenda out.
This video covers the famous Dover trial Intelligent Design on Trial
It is quite funny to watch in places, the anti-evolution team just lied and cheated all the way through, and then when the Republican judge decided against them, good Christians took it upon themselves to issue the judge with death threats and tried very hard to smear his name.
I prefer this talk by Eugenie Scott
as it covers the Dover trial from the preparation of the science they presented as evidence as well as the sneaky tactics used by the Creationist/ID side.
After that, you might be interested in this talk by Matthew Chapman
, he also covered the Dover trial, with a slightly different angle: he is the great-great grandson of Darwin.

The important thing about the Dover case is that the evidence presented showed a few things:
- Creationism & Intelligent Design are the same thing
- the Discovery Institute has no problem publishing known lies
- there is no actual theory on the Creationist / ID side; just a whole lot of criticism of a theory they don't like
- the Creationist / ID movement has a religious & political agenda
- the Discovery Institute keeps changing its tactics to try to get past the First Amendment that prohibits religion being taught in the classroom
