It's really quite easy to investigate the process of speciation. What's hard is to investigate the existence of an Intelligent Designer.
The only claim of IDers so far is that since they view Evolution as problematic, then obviously there must be an Intelligent Agent that put us here.
Sorry, that doesn't wash. There are many more scientific areas of study that are much more problematic than Evolution, and those problems don't require an answer that "God did it". Litterally any unexplained thing can labeled an act of God.
So how would you go about scientifically testing for the existence of God? Propose experiements.
Be specific.
Be specific.
You seem to have mistaken me for one who has taken up a position in favor of intelligent design. Actually, all I have done is proposed that the author of the article under discussion be refuted on the basis of his article, rather than the weight of his credentials. If he's really the fool he's made out to be, the peer review process should deal with him quite handily; that's what it's for, after all.
I have also made the observation that it's difficult to design an experiment to investigate the origin of speciation...a contention that I stand by, despite your blithe dismissal. All I meant by it is to point out that the field, being as theoretical as it is, leaves room for a great many academic pi$$ing contests.
I see no need to add another one to the roster, academic or not, so I'll just bow out now, thanks.
Right back to "how many angels can dance on the head of a pin." (!!)
One of the difficulties here is, what if God doesn't want to cooperate with the experiments? How can you even tell if the experiments are, well, effective? ;-)
You end up having to make assumptions in advance, one way or the other, with no "sure-fire" way to test them.
"Unfalsifiable" is one adjective used to describe the situation--but "Unverifiable" might apply as well...
Cheers!
