✦ Synopsis

Abstract

Data from 142 male and 43 female samples of African populations have been used to analyze the geographical variation of digital dermatoglyphics (arches, loops, whorls, and pattern intensity index) in Africa. The patterns of geographical variation have been summarized as contours of sixth‐degree polynomial surfaces by means of trend‐surface analysis.

As pointed out by early studies, Africa exhibits geographical clines of digital dermatoglyphic patterns. However, only some of the frequency gradients previously described for the region find confirmation in the present study.
