this study estimated the magnitude of sexual dimorphism in a relict sheep from catalunya (ne spain), called fardasca,using geometric morphometric techniques. for these analyses, a total of 18 skull specimens (2 adult males and 16 females) were studied. our results suggest that the breed is not cranially dimorphic, so sex determination using landmarks described here as criteria is likely to yiel...

Previous research on the causes of craniometric variation within and among human populations has invoked both genetic and environmental explanations. Recent studies of modern populations in the United States and Portugal, among other populations, suggest that changes in environmental conditions have resulted in significant changes in cranial morphology. While similar changes in cranial morpholo...

OBJECTIVE The purpose of this study was to evaluate the significance for sex determination of the measurement of the area formed by the xerographic projection of 3 craniometric points related to the mastoid process: the porion, asterion, and mastoidale points. METHOD Sixty skulls, 30 male and 30 female, were analyzed. A xerographic copy of each side of the skull was obtained. On each xerograp...

Recent studies comparing craniometric and neutral genetic affinity matrices have concluded that, on average, human cranial variation fits a model of neutral expectation. While human craniometric and genetic data fit a model of isolation by geographic distance, it is not yet clear whether this is due to geographically mediated gene flow or human dispersal events. Recently, human genetic data hav...

The study was performed in 30 subjects with class II/1 and 30 subjects with class II/2 anomalies. The aim of the study was to assess the extent to which class II anomalies influenced individual craniometric and gnathometric dimensions as well as to determine whether there were any significant differences between the two subgroups. Craniometric dimensions were measured in each subject by means o...

The origins of the ancient Egyptian state and its formation have received much attention through analysis of mortuary contexts, skeletal material, and trade. Genetic diversity was analyzed by studying craniometric variation within a series of six time-successive Egyptian populations in order to investigate the evidence for migration over the period of the development of social hierarchy and the...
