[Man among the primates. His position after multivariate analysis of his mandible].

Abstract

Multivariate analysis are applied to 31 ensembles (species of Primates or human breeds), in 31 mandibular linear parameters. A reciprocal averaging show that first factorial plane reproduce the Simpson classification, simplified in 4 groups, with 63.3% of whole inertia. Discriminant analysis calculated with 13 parameters, situates these 4 groups in 3 planes. The D2 Mahalanobis generalised distance is calculated between all groups. The most contributive parameters to generalised distances are inter-molar width and breadth between foramen mentales.
