Abstract

The use of non-metric skeletal traits to compute population distance statistics assumes strong genetic control of trait expression. An investigation of bilateral asymmetry frequencies of human cranial and postcranial non-metric traits shows that asymmetry is common. This suggests that environmental stress, as well as the genotype, is important in controlling trait frequencies.
