I'm glad Orr mentioned the genomic doubling in vertrebrates. (For one thing, I didn't know about that. I'd like to read more about it.) Otherwise, ID creationists would faint, come to, dust themselves off and claim proof that all the genomic "information" was front loaded--and that all the rest of diversity didn't include any new information, just fiddling with whatever was already in the genome. Blah blah blah.
I agree with Orr that switching probably plays a decisive role in evolutionary schema, but that its not so extreme as to overturn any current paradigms in evolutionary thought. I wish the media would be more responsible about the way they portray scientific discoveries.
