South Amerindians are frequently thought of as a rather biologically homogeneous megapopulation. However, when native South Americans are assessed by information coming from DNA variability analysis, they resolve into two, major distinct entities of Eastern and Western zones. The purpose of this study is to investigate if the same dual pattern emerges from craniometric data. We approached this ...

On the basis of karyologically identified individuals of the common vole Microtus arvalis and the sibling vole Microtus rossiaemeridionalis from Europe and the Asiatic part of Turkey, a canonical craniometric classification function for the differentiation of these sibling species was worked out. The function is sex-independent and includes four craniometric parameters measured in millimeters (...

Tumors of the base posterior cranial fossa are among most difficult for surgical treatment in neurosurgery. Numerous studies being conducted on factors that determine clinical manifestations and outcomes. The aim study was to linear angular parameters patients with extracerebral neoplasms evaluate their effect results treatment. Craniometric performed 115 sub-tentorial tumors. A computer progra...

This study sets out to consider the influence of geographical scale on association between molecular genetic differentiation and craniometric phenotypic in recent human populations. We employ interpopulation distance measurements for three different anatomical regions skull systems markers 30 Eurasian Our original dataset comprises 703 male skulls measured 21 mid-facial, 15 neurocranial 6 mandi...

The designation of Homo floresiensis as a new species derived from an ancient population is controversial, because the type specimen, LB1, might represent a pathological microcephalic modern Homo sapiens. Accordingly, two specific craniometric ratios (relative frontal breadth and cerebellar protrusion) were ascertained in 21 microcephalic infants and children by using MRI. Data on 118 age-equiv...

Body weights of adult baboons (genera Papio, Mandrillus, and Theropithecus) were gathered from notes of collectors and museum records. However, these data were insufficient to establish mean body weights for all baboon groups. Thus, log cube roots of mean body weights were regressed as functions of the logs of several cranial and dental variables. The resulting least squares regression coeffici...

The presence of Nycticebus coucang in Singapore is doubtful, and there have been publications expressing such doubts. This study tries to establish the presence of native lorises in Singapore, and the possibilites that sightings might be escapees. Night surveys, craniometric tests to compare lorises from the regions surrounding Singapore, and external morphology comparisons from photographs wer...

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 anatomy...
