Behe made the claims about unselected mutations, and in his responses to
his critics in 2000 he claimed that well matched, and the order and
arrangement of mutations would make the system his type of IC.

Behe doesn't like to admit it, but his changes have been trying to
maintain the IC stupidity, while keeping IC something that could not
have evolved by natural mechanisms. The stupid "scientific test" for IC
that both Minnich and Behe put up in their Dover testimony was to start
with a bacteria with out a flagellum and get it to evolve a flagellum.
If a flagellum could have been evolved then Behe would be wrong and IC
will have failed. Both Minnich and Behe admitted that they had never
attempted the only scientific test that they proposed, so it was obvious
that neither cared about IC being testable.

Behe as always admitted that biological evolution is a fact of nature.
He has admitted that his designer might be dead because he doesn't see
any evidence for designer activity in the last couple of hundred million
years of biological evolution. His last IC system evolved in
vertebrates over 400 million years ago (the adaptive immune system).
His flagellum evolved in bacteria both Archea and Eubacteria over a
billion years ago. That is the major reason why Behe can't tell anyone
if the flagellum is his type of IC. It evolved so long ago that much of
the molecular history has been destroyed by multiple mutations a pretty
much ever site in the proteins that can change.
Behe relies on biological evolution to help him demonstrate the order
and arrangement of the mutations that will make a system his type of IC.
He thinks that there are orders and arrangements of mutations that
would need to be done by his designer. His crowing about finding two
unselected steps in the evolution of systems demonstrates how he thinks
that he will be vindicated. He admits that two are not enough, but he
claims that this is the edge of IDiocy, and that biological evolution
should not be able to go beyond that. Just like any other science
researchers have just determined what happened and it isn't what Behe
needs. Labs like Thornton's lab can use a top down analysis to work
backwards and determine the order of mutations in the evolution of the
proteins that they are working with. Behe accepts their work and likely
hopes that such work will vindicate him, but so far it hasn't. He
hasn't initiated such research for any of his systems. It is just more
science that he doesn't want to do because he doesn't want to know the
answer based on what has already been found.
