Ask them for an exact measurement process. What definition of information it's supposed to measure and how it applies to genetics.
Then, once they avoid doing that like the plague, you can hit them with a few studies that show step-wise evolution of major changes in systems.
My personal favorite is Darwinian Evolution on a Chip. http://www.plosbiology.org/article....0060085
Because it shows the stepwise changes in the RNA sequence from the original product all the way through the final sequence which has a 90-fold improvement over the original.
Plus, there is an example of an early negative mutation being a prerequisite mutation for further increasing the effectiveness of the sequence.
Then, you can ask them, exactly where the designer stepped in. Dr. Joyce is still around and they can ask for the original data, including the sequences that were collected throughout the experiment... if they dared.
No, it's not a change in species, genus, or family, but only creationists have those requirements anyway.
You might read up on evolutionary developmental biology as well. I predict that the next move will be the whole "How did body plans develop".
It's in the creationist playbook.
Ignored by those who can't provide evidence for their claims.
