| Research Abstract |
The growth balance of the upper and lower limbs, and the trunk, was represented by the developmental change in the cross-ratio. We introduced the triple-ratio, which is constant by the Mobius transformation and can deal with four consecutive structures, such as the metacarpal bone and proximal, middle, distal phalanges. The difference of the triple-ratios of the fingers among the primates corresponds to the difference of their behavior, such as arboreal, semi-arboreal, or terrestrial. The cross-and triple-ratios may be applicable for the assessments of the growth balance, and Mobius transformation may be used as a function that represents the relationship between the skeletal structure of the hand and its mechanics.
