Öğe The frequency of metopism in Anatolian populations dated from the Neolithic to the first quarter of the 20th century(Wiley, 2008) Eroglu, S.Metopism, which is defined as a condition in which the two pieces of the frontal bone fail to merge in early childhood, displays varying degrees of incidence. In this study, the variation of the frequency of metopism across historical periods is investigated on the skulls of 487 adults from 12 different Ancient Anatolian populations dated to various periods of history ranging from the Neolithic to the first quarter of the 20th century. In addition, the study also examines the relationship of metopism to sex and cranial form. It is revealed that the frequency of metopism showed a relative increase across time periods in Anatolia after the Neolithic Period, with the exception of the Cevizcioglu Ciftligi population. However, no significant relationship was found between metopism and cranial form or sex. It is found that the frequency of metopism in Ancient Anatolia had a distribution range of 3.3-14.9%. This distribution shows that the inhabitants of Anatolia have a heterogeneous genetic make-up due to the geographical situation of Anatolia, which has been open to gene flow both in the past and at present.Öğe Variations in the form of the hypoglossal canal in ancient Anatolian populations: Comparison of two recording methods(Elsevier Gmbh, Urban & Fischer Verlag, 2010) Eroglu, S.In this study, the frequency of bridging of the hypoglossal canal was investigated on 324 skulls belonging to 10 ancient Anatolian populations recovered from various archaeological sites and dated from Early Bronze Age to the first quarter of the 20th century. The change in the frequency of bridging trait in the hypoglossal canal that has already been recorded according to both the traditional method (absent or present) and the graded method (0-5) was analysed here in relationship to age, sex, skull side and population. The results revealed no significant relation between the bridging of hypoglossal canal and age or sex. Both recording methods showed that the studied samples of ancient Anatolian populations exhibited a homogenous structure and they were found to differ considerably from other populations which inhabited lands other than Anatolia. This indicates that these two recording methods produce similar results in comparing populations. The differences between the sides were found to be significant with the detailed recording method as opposed to the dichotomous method. This asymmetry emerging with the detailed recording method is considered to be important in determining the effect of environmental factors upon the trait.Öğe Why did the frequency of palatine torus increase in the ancient Anatolian populations?(Elsevier Gmbh, Urban & Fischer Verlag, 2008) Eroglu, S.; Erdal, Y. S.The frequency of the palatine torus varies in various Populations from different regions of the world. In this Study, the change of frequency of palatine torus is examined using 387 skulls from 12 different ancient Anatolian populations in various periods ranging from the Early Bronze Age to the first quarter or the 20th century. While the frequency of palatine torus is 45% in the Early Bronze Age, this ratio steadily increases to 87% in the Ottoman Period and finally declines to 40% during the recent period. It was determined that the increase in the frequency of the palatine torus is statistically significant across different periods from the Early Bronze Age until the 20th century. Constituting a passageway between Asia and Europe and being located oil the crossroads of the most important trade route of the Medieval Period, the Silk Road, Anatolia is known to have been subjected to recurring invasions and migrations since the 11 th century A.D. Therefore, it is possible to say that, with the introduction of the Mongoloid influence in Anatolia, genetic flow has had a significant role in the observed increase in the frequency of this trait.
