The article grudgingly admits the obvious, that Neanderthals invented jewellery LONG before early modern humans, and other sources show that Neanderthals invented cave-art, flint technology etc. LOng before early modern humans as well. So the articles OoA(Out-of-Africa) premise is already proven false beforehand. The only good part of the article is when it has a separate subsection on how Neanderthals perhaps became extinct as a result of getting into contact with new diseases(presumably from arriving early modern humans).
