Even regarding looks, when I look at images of Neanderthals such as this guy on the Smithsonian's web site (https://humanorigins.si.edu/evidence/human-fossils/species/homo-neanderthalensis https://humanorigins.si.edu/evidence/human-fossils/species/h...), I see a human, and nothing more. Leaving aside the idea that Neanderthals probably lived in groups with other Neanderthals, and modern humans with modern humans, I don't have a problem believing they may have intermated.
