Abstract

Intraspecific variability of a modern human mandible was determined using a principal component analysis following by a varimax rotation. Individual standardized data for the following series were included in the analysis: Eskimo from Ekven, 4-7 centuries AD, – 61 jaws; Eskimo from Naukan, 19-20 centuries AD, – 23 jaws; Anglo-Saxon from Dunstable, 5-6 centiries AD, – 40 jaws (Dingwall, Yaung, 1933); Ancient Egyptian series, IX dynasty, – 37 jaws (Woo, 1930); series of Badari culture, Egypt, 5-3 centuries BC, – 32 jaws (Stossiger, 1927); Hokiens, southeast China, early 20 century, – 38 jaws (Harrower, 1928); Hylams, island Hainan, China, – 39 jaws (Harrower, 1928); Tamils, India and Ceylon, – 33 jaws (Harrower, 1928). During the analysis three principle components (PC-1, 2, 3) were determined. The first PC describes the overall size of a bone and is not associated with angular dimensions. PC-2 characterizes the variability of a mandibular angle (M-79) and a height of branches (M-70). PC-3 strongly correlates with a height of a symphysis (M-69) and an angle of a chin protrusion (
