This diploma thesis deals with sexual dimorphism and interpopulation variability of skull morphology between recent Egyptian population and a historical population, which is not geographically distanced but originates from the Old Kingdom period (Egypt, 2700-2180 BC). Estimating sex and population affinity is an important part of the process of building a biological profile of unknown human remains, and the skull is one of the best parts of the skeleton to estimate these attributes. Sex estimation is based on the existence of sexual dimorphism, which is very population specific, and sex determination is more reliable when population-specific methods are applied. Therefore, it is required to perform population affinity estimation before sex determination. A total of 143 adult specimens were included in the analysis. 47 three-dimensional exocranial meshes of skulls of individuals originating from the Old Kingdom period (31 males and 16 females) and 96 CT images of the heads from the recent Egyptian population in the age range of 18-86 years. (49 males and 47 females). The material was evaluated using the methods of geometric morphometry. In the analysis of the form, significant differences between the sexes were found. The most sexually dimorphic areas were the supraorbital arches, glabella, arcus...
