I'm not following what you mean by this ... could you clarify your statement?
Basically, this guy is preaching "micro-evolution" because all he sees is a single step, and intentionally refuses to see the evidence of a series of "steps."
He doesn't have (or refuses to use, more likely) the mental ability to see how multiple small changes can accumulate to create something completely different.
It is akin to seeing hand drawn animation frames not running through the projector and not seeing how one can have motion --- just a bunch of pictures, each slightly different.
