• A bi-level nasal floor, although present in most Pleistocene and recent human samples, reaches its highest frequency among the western Eurasian Neandertals and has been considered a feature distinctive of them. Early modern humans, in contrast, tend to feature a level (or sloping) nasal floor. Sufficiently intact maxillae are rare among eastern Eurasian Pleistocene humans, but several fossils provide nasal floor configurations. The available eastern Eurasian Late Pleistocene early modern humans have predominantly level nasal floors, similar to western early modern humans. Of the four observable eastern Eurasian archaic Homo maxillae (Sangiran 4, Chaoxian 1, Xujiayao 1, and Chang-yang 1), three have the bi-level pattern and the fourth is scored as bi-level/sloping. It therefore appears that bi-level nasal floors were common among Pleistocene archaic humans, and a high frequency of them is not distinctive of the Neandertals.
