    Abstract
    Introduction: Neanderthals, our extinct
    relatives, exhibited distinct nasal
    morphology compared to Homo sapiens.
    Objectives: This study explores these
    differences through a comparative
    analysis of cranionasal measurements.
    Material and Methods: Data on Neanderthal
    nasal features were obtained from
    existing paleoanthropological literature,
    focusing on 16 hominid fossils. A parallel
    sample of 38 modern human CT scans was
    retrospectively reviewed, with
    measurements focusing on nasal region.
    Results: Neanderthals displayed
    significantly larger nasal cavities with
    increased basion-nasion and basion-prosthion
    distances, wider intercanine dimensions, and
    larger nasal breadth and height compared to
    modern humans. Choanal width and nasal index
    did not differ significantly. Conclusions:
    These findings suggest functional
    adaptations in Neanderthal nasal morphology,
    potentially aiding in thermoregulation
    within cold environments. Further research
    is needed to fully understand the
    evolutionary significance of these
    adaptations.
