The article sets up a bit of a straw man (or maybe a motte-and-bailey) I think, because it says "all mammal brains (and most likely, all vertebrate brains as well) are built from a single manufacturing plan using the same kinds of neurons."; but I'm not sure that really refutes the notion that most of us have when we think of the lizard brain. Ontology doesn't recapitulate phylogeny, but we do have a cerebellum, and our actions and reactions happen along a broad spectrum of temporal control and conscious awareness.
