Toward elucidating the causes of brachycephalization, the correlations between the measurements of the neurocranium and the thoracic vertebrae were examined by means of principal component analysis (PCA) and Kaiser's normal varimax rotation method. In most of the direct results of the PCAs, the first principal component was significantly correlated both with the cranial length and/or basibregmatic height and with the sagittal and/or transverse diameters of the vertebral body; and, in one third of the rotated solutions for males, the factor correlated with the cranial length always had significant correlations with the sagittal diameters of the vertebral body. The concrete causes for these associations should be examined in the future.
