My point exactly, an important distinction is being ignored, Neanderthals larger brains needed to oxygenate more than their counterparts.

Very interesting study and hypothesis regarding the Neanderthal’s more massive turbo charged air intake. A more important distinction was ignored however, Neanderthals had larger brains than even modern humans. This does not detract away from their greater need to oxygenate since our heads are big consumers of it.
