Abstract Climate is thought to be one of the factors affecting the distribution of nasal form as represented by the breadth and height of the skeletal nasal aperture. A model of nasal function is developed to predict influences on the skeletal nasal dimensions by selection acting upon the external nasal passage and aperture. Cranial series from Alaska and Australia, each series representing a climatic continuum from warmer and moister conditions to cooler and drier conditions, verify the predictions. These data suggest conditions for testing hypotheses about human variation.
