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.
