Nope. And I'm not ashamed to say it.
I pride myself on having a fairly strong grasp of the English language. While I may be relatively dense in some subject matter (math, for example), I'd put my reading, vocabulary and comprehension skills up against most anyone's.
I'm not saying it's not an accurate definition... I'm saying it's highly unlikely that PrezBO used it with that obscure definition in mind. If he was THAT astute, he wouldn't have said "reptilian SIDE of our brains"... he'd have said "component", since even in microevolution, changes occur on BOTH sides of the brain, not just one exclusively.
I think he may have meant to say, "some pre-evolutionary component" of our brain... as in, some leftover evolutionary feature that causes us to fear that which is different (which would have made total sense). Still, wouldn't reconcile very well with a Creationist viewpoint, but at least it would have been more accurate.
