Abstract: | The data used in this study are the fingerprints of 744 females from 6 Sardinian linguistic groups. We analyzed 15 dermatoglyphic
variables of directional asymmetry, namely the right vs left signed differences between i-th homologous fingers for larger
ridge counts, radial counts and ulnar counts. Principal components analysis of the dermatoglyphic variables in the females
of Sardinian linguistic groups revealed a pattern of biological relations among the groups which is consistent with their
linguistic, but especially historical and demographic, backgrounds. |
