TURNED ON--A revolution in the field of evolution?

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.

Yeah.  I was sorta skimming it at the end.  What'd I overlook?

Towards the end he says

The point isnít that evo devo is not important; it surely is. For the first time, we have a good understanding of how particular changes in DNA cause particular changes in embryos, which, in turn, cause particular changes in species. The point is that not all significant science turns our world upside down. Despite the nearly irresistible romance of the scientific revolution, the history of evolutionary biology might end up looking a lot more like evo devoís own history of the animal kingdom: a few radical innovations early on, followed by some intensely interesting tinkering

(a few days later...)

Well?   I'm genuinely curious!  Stevestory, please, if you have a point here, explain it. :)
