Model-based clustering is applied to 2,504 crania of 28 populations of recent Homo sapiens using 57 cranial metric variates. This technique uses no a priori knowledge about the population affiliation of each skull. Model-based clustering varies the number and form of the clusters and selects a “good” model, showing a balance of data fit and parsimony, using the Bayes Information Criterion. Four...

The purpose of this study is to present the biological affinity of four Taiwanese Indigenous groups. Previous studies based on linguistics and ethnography had shown that there are differences between the indigenous groups in Taiwan (Ferrell 1969; Utsurikawa et al. 1935). Archaeological remains also indicate that there was a wide variety of groups (Tsang 1995). In order to provide some biologica...

Abstract BACKGROUND. Fractures of the naso-orbito-ethmoido-maxillary (NOEM) complex are frequently acquired post-traumatic lesions, with both aesthetic and functional consequences, if diagnosis is not promptly established surgical correction delayed. OBJECTIVES. This study was conducted in order to facilitate NOEM fractures by using anthropometric measures. The aim obtain normal mean values eva...

Debates surrounding the nature of the Neolithic demographic transition in Europe have historically centred on two opposing models; a 'demic' diffusion model whereby incoming farmers from the Near East and Anatolia effectively replaced or completely assimilated indigenous Mesolithic foraging communities and an 'indigenist' model resting on the assumption that ideas relating to agriculture and an...

A new species of swamp rat of the genus Scapteromys from the Meridional Plateau of Southern Brazil is described. Morphological, molecular, and karyological analysis support the recognition of the new species, distinct from S. aquaticus and S. tumidus. Scapteromys sp. nov. is significantly smaller than the congeneric taxa considering most of the external and craniometric measurements and the pel...

The Institute of Forensic Medicine, Copenhagen, houses a collection of historical skulls of unclear origin, marked with a general geographic or "racial descriptor". Would these historical skulls be of any value for the forensic odontologist and anthropologist concerned with teaching and casework? We tried to clarify this question by recording non-metric dental traits and by performing craniomet...

Introduction: The existence of sexual dimorphism in human skeletons especially skull and its medico-legal importance had long been studied [3] [2,1]. This study has investigated the existence of sexual dimorphism in cranial dimensions of Nigerian population. Methods: A total of 100 adult dry skulls, (78 males, 22 females) free from damage and deformity fully ossified from Departments of Ana...
