“…It is also interesting to note that the dimension which is the most dimorphic (acetabular diameter) is one that is associated simply with robusticity, and has nothing to do with child bearing at all. This measurement was also found to be one of the best indicators of sexual dimorphism in similar studies [5,11,34].…”

The ability to determine sex from unknown skeletal remains is vital, and methods to do this on the various bones of the human skeleton have been researched extensively. Many researchers have emphasized the need for population specific data for methods which are based on measurements, as there are vast differences in body size in various populations. The pelvis is known to be the most sexually dimorphic part of the human body, and no discriminant function formulae for this bone are available for Greek or other Mediterranean groups. The purpose of this study was therefore to develop discriminant functions which can be used for sex determination on measurements of the pelvis of modern Greeks. A sample of 97 male and 95 female pelves in a skeletal collection housed in Heraklion, Crete, was used. Measurements were taken from the articulated pelvis, single os coxae and the sacrum. Discriminant function formulae for all measurements and various combinations were used in order to assess the degree of sexual dimorphism in various parts of the pelvis, and to make the formulae usable on fragmented remains. For the single os coxae, average accuracies of 79.7 -95.4% (79.1 -93.5% on crossvalidation) were found. However, it was found that measurements of the sciatic notch were unreliable and yielded poor results, and it is advisable that this characteristic must only be used as a last resort. Dimensions of the sacrum were not very dimorphic (average accuracy 60.9%), while measurements from the articulated pelvis yielded poorer results than that from single innominate bones. The diameter of the acetabulum was the single most dimorphic characteristic, providing on average 83.9% accuracy when used in isolation.

“…Although morphometric traits are more objective, a random set of measurements may not invariably be conclusive. 8 The most widely used statistical technique has been multivariate discriminant analysis of sex determination for skeletal measurements. 13 Discriminant analysis is used to classify individuals into two or more alternative groups on the basis of a set or measurements.…”

“…The studies for sex determination are based on the dimorphism between the sexes that is present in the majority of human bones. 1,2 The determination of sex, age and race is 100% using skeleton [3][4][5][6][7] , 95% reliable when using the pelvis alone, 8,9 92% using the skull alone 10 and 98% using the pelvis and skull. 8,9 Skull is probably the second best region of the skeleton to determine the sex since skull is composed of hard tissue and is the best preserved part of skeleton after death; hence, in many cases it is the only available part for forensic examination.…”

“…13 The methods of sex determination on skull are obviously imperfect; although efforts are constantly being expanded to improve them. 7,8 Discriminant function analysis is a statistical technique that enables the researcher to examine the relationships among two or more groups based on any number of variables simultaneously, and is used to predict group membership from a set of predictors and to classify cases into the values of a categorical dependent, usually a dichotomy. Discriminant function analysis is increasingly utilized for sex diagnosis of skeleton measurements.…”

Objective: The present study is an attempt to develop a method to determine sex from the skull with lateral cephalometric radiograph using discriminant function analysis. Study design:The superciliary ridges, frontal sinuses, sella, cranial base and mastoid process were adopted as objects of lateral radiographic cephalometric measurements. The present study included cephalometric radiographs of 100 Indian adults chosen randomly from the records, each cephalometric radiograph was traced and nine linear and five angular measurements and one proportion were recorded for each case.Results: Using the discriminant functional analysis, the randomly chosen 100 adult patient cephalometric radiographs were classified into two sexual groups 84% of accuracy. Conclusion:From the results of the present study, it may be concluded that sex determination can be done with greater reliability.

Bergmann's and Allen's Rules predict a relationship between climate and morphology as a thermoregulatory adaptation. These ecogeographic principles predict/explain change in the ratio of body surface area to body mass in hot and cold climates. With regard to Allen's Rule we would expect short and relatively broad limb proportions. Such adaptation should be observable in skeletal architecture. This paper provides a test of Allen's Rule using osteometric data for the second metacarpal from the Sadlermiut of Southampton Island, Northwest Territories, Canada. Following adjustment for body size, ANOVA by sample and sex shows the Sadlermiut second metacarpal to be shorter, wider at the base and deeper at the distal metacarpophalangeal joint, in comparison to an historic sample of European settlers. This pattern of difference suggests an Inuit hand with a thermally adapted morphology, viz. a large mass relative to surface area. Copyright © 1999 John Wiley & Sons, Ltd.
