BROOKLYN, NEW YORK—A new study of the Neanderthal nasal complex suggests that Neanderthals were a distinct species separate from modern humans. Rather than comparing Neanderthal noses to those of modern Europeans and the Inuit, whose nasal complexes are adapted to cold and temperate climates, the scientists, led by Samuel Márquez of SUNY Downstate Medical Center, examined the nasal regions of diverse modern human population groups with 3-D coordinate data and CT imaging. They found that the Neanderthal upper respiratory tracts had a mosaic of features not found among any population of modern humans as a result of a separate evolutionary history. “The strength of this new research lies in its taking the totality of the Neanderthal nasal complex into account, rather than looking at a single feature. By looking at the complete morphological pattern, we can conclude that Neanderthals are our close relatives, but they are not us,” team member Jeffrey T. Laitman of the Icahn School of Medicine and the Center for Anatomy and Functional Morphology told Science Daily. To read more about Neanderthal genetics, see "Should We Clone Neanderthals?"
