GOP Creationist Believes in Evolution Within Phyla

Check this out:
In addition to the usual nonsense, there is something interesting here. This guy says he believes in evolution up to a point, that is, within a phylum. Creationists all along have endorsed evolution within “kinds,” whatever those are. Supposing that this guy knows what a phylum is, he seems to extend the “kind” all the way to phyla. In short, he seems to think that you or I could have evolved from any chordate ancestor. I guess he would endorse the old song (To the tune of “It’s a Long way to Tipperary”):

It’s a long way from Amphioxus
It’s a long way to us.
It’s a long way from Amphioxus
to the meanest human cuss.
Goodbye fins and gill slits.
Hello teeth and hair!
Its a long, long way from Amphioxus,
But we came from there!

Really?!? Of course, I cannot see how this is not giving away the store. You and I might have evolved from, say, Pikaia, back in the Cambrian, but evolution cannot handle a bigger change then that. Howcome???
