Eastern Eurasian archaic humans featured a bi-level nasal floor as seen in Neandertals
In an assessment of the nasal floor configurations of the available and sufficiently intact, if still incomplete, paleoanthropologists from Institute of Vertebrate Paleontology and Paleoanthropology (IVPP), Chinese Academy of Sciences, Washington University and University of Missouri, found that archaic Homo maxillae from eastern Eurasia seem to have a prevalence of the bi-level pattern similar to that seen in the western Eurasian Neandertals, while early modern humans from eastern Eurasia mostly exhibit the level floor pattern predominant among early and recent modern human populations, indicating that bi-level nasal floors were common among Pleistocene archaic humans, and a high frequency of them is not distinctive of the Neandertals as thought before.
