As a step toward elucidating the causative factors of morphological characters, ecological correlations were estimated between specific morphological characters, the gene frequencies for biochemical/physiological characters, and environmental factors. Principal component analyses of the ecological correlations or the rotation of their results showed that the cephalic index had significant inverse associations with phosphoglucomutase 1, average annual temperature, and the amount of annual rainfall; that the nasal index had an inverse association with glyoxalase I and, simultaneously, positive associations with average annual temperature and the amount of annual rainfall; that the mesiodistal crown diameter of the maxillary first molar had significant associations with haptoglobin-alpha and average temperature in the coldest month; and that the buccolingual crown diametr of the maxillary second molar had an inverse association with alleles MS of the MNS system and, simultaneously, positive associations with average annual temperature and the amount of annual rainfall. These findings suggest that a morphological character comprises a character complex together with some biochemical/physiological characters which support the emergence or existence of the morphological character in a certain environment, or, merely, that an ecological association between a morphological character and a biochemical/physiological character is due to two independent adaptations to the same environmental factor or due to gene flow.
