Environment-Related Variation in the Human Mid-Face
International audience Previous studies that have examined mid-facial morphology in geographically dispersed and genetically diverse groups of humans have shown a strong adaptation of the nasal part to extreme cold environments, which was not observed in non-Arctic regions. However, it remains uncle...

Additionally, partial least square analyses indicate that tropical and subtropical environments are associated with smaller zygomatic and more triangular nose aperture compared to more temperate environments. These findings suggest that temperate and tropical climates have induced adaptation of zygomatic and nasal parts of the mid-face in humans, and that this adaptation was probably driven by temperature and sunlight exposure conditions.
