“Ear infections likely killed off the Neanderthals...” This bit of science brought to you by the same schmoes pushing man-made global warming.
I agree with you as they have no real way to prove such a theory. They just dream it up and pass it on as settled science.
I caught on to their far out conclusions when watching a T-Rex show where they said the monster had an outstanding ability to smell. This was based on a rather large olfactory cavity. For an animal that primitive it is likely such a large cavity could be proportionately primitive, meaning size has nothing to do with how well it can smell anything.
