A bioclimatic model is evaluated as an explanation of variation in cranial capacity among 122 ethnic groups. Distribution of absolute and relative endocranial volume is mapped. Significant correlations occur with all nine climatic variables examined. Major foci of adaptation occur with solar radiation, vapor pressure, and winter temperature. Global mean trait increase is 2.5 cm per degree of equatorial distance. The interactive geometry between cranial size and shape is described, with… Expand
