ANTHROPOMETRIC COMPARISM OF CEPHALIC INDICES BETWEEN YORUBA AND BENIN ETHNIC GROUPS RESIDING IN OKADA TOWN, EDO STATE.

Project Abstract

Anthropometric studies play a crucial role in understanding human diversity and population variations. This research project focused on comparing cephalic indices between the Yoruba and Benin ethnic groups residing in Okada town, Edo State. Cephalic index is a valuable anthropometric measurement that provides insights into skull shapes and variations among different populations. The Yoruba and Benin ethnic groups are two prominent ethnic groups in Nigeria with distinct cultural and historical backgrounds. The aim of this study was to investigate and compare the cephalic indices of individuals from the Yoruba and Benin ethnic groups living in Okada town. The research involved measuring and analyzing cranial parameters such as head length, head width, and cephalic index. These measurements were taken using standard anthropometric tools and techniques. The data obtained were then analyzed statistically to determine if there were significant differences in cephalic indices between the two ethnic groups. The findings of the study revealed interesting results regarding cephalic indices among the Yoruba and Benin ethnic groups in Okada town. The results indicated that there were variations in cephalic indices between the two groups, suggesting differences in skull shapes and proportions. These differences could be attributed to genetic factors, intermarriages, or other environmental influences that have shaped the cranial characteristics of these populations over time. Furthermore, the study highlighted the importance of conducting anthropometric research within specific population groups to understand the variations and similarities in physical characteristics. By comparing cephalic indices between the Yoruba and Benin ethnic groups, this research contributes to the broader field of anthropometry and provides valuable insights into population diversity within Nigeria. In conclusion, this study emphasized the significance of anthropometric comparisons in elucidating human biological variations and population differences. The research on cephalic indices between the Yoruba and Benin ethnic groups in Okada town sheds light on the unique cranial characteristics of these populations and underscores the importance of considering cultural and genetic factors in anthropometric studies. Further research in this area could provide additional insights into the evolutionary history and population dynamics of diverse ethnic groups in Nigeria.

Project Overview

<p> </p><p><strong>INTRODUCTION</strong></p><p><strong>BACKGROUND OF THE STUDY</strong></p><p>Anthropometry deals with the measurement of <a target="_blank" rel="nofollow" href="https://www.modishproject.com/ethnic-militias-nationalism-nigeria-comparative/">physical sizes and shapes</a>&nbsp;of human body (D. Poswillo, 1963). In <a target="_blank" rel="nofollow" href="https://www.modishproject.com/framing-broadcasts-indigenous/">differentiating people</a>&nbsp;of different ethnic backgrounds, nutritional status, and gender, according to G. V. Shah and H. R. Jahhav, 2004, anthropometric data seems to be useful. <a target="_blank" rel="nofollow" href="https://www.modishproject.com/quality-acceptability-microbial-2/">Several measurable anthropometric</a>&nbsp;parameters or variables have been developed over the years for establishing possible differences amongst different groups (G. V. Shah and H. R. Jahhav., 2004).</p><p>According to G. V. Shah and H. R. Jahhav (2004), S. W. Lobo, T. S. Chandrashekhar, and S. Kumar (2005), M.J.Golalipour (2006), Cephalic index is one of such very useful measurable anthropometric variables used in physical anthropology to determine geographical gender, age, and racial and ethnic variations. They proved that comparison of changes in cephalic index between parents, <a target="_blank" rel="nofollow" href="https://www.modishproject.com/solid-waste-management/">offspring, and siblings</a>&nbsp;gives clues to genetic transmission of inherited characters or traits which play a role in forensic science. Argyropoulos and Sassouni(1989) showed that morphological features of different races and ethnic groups are not randomly distributed but appear in geographic clusters. Arguably, Cephalometry continues to be the most versatile technique in the investigation of the<a target="_blank" rel="nofollow" href="https://www.modishproject.com/phosphorus-grain-yield/">&nbsp;craniofacial skeleton</a>&nbsp;because of its validity and practicality (G. T. McIntyre and P. A. Mossey, 2003). Cephalometry is associated with the morphological study of all the structures present in the human head. Cephalometry is the scientific measurement of the dimensions of the head usually through the use of standardized lateral skull radiographs (I. EI-Feghi et al, 2004). Based on the above factors, anthropometric studies are <a target="_blank" rel="nofollow" href="https://www.modishproject.com/religious-conflicts-nigeria-solutions/">conducted on the age, sex</a>, and social or ethnic groups in certain geographical zones (G. V. Shah and H. R. Jahhav, [2004], P. Williams et al, [2003], M.J.Golalipour et al, [2003], M.J.Golalipour et al, [2005], B. C. Didia and D. V. Dapper, [2005], S. H. Garba, [2008], H. B. Fawehinmi and A. M. Eroje, [2009], O. Joy et al, [2009], G. S. Oladipo et al, [2009], G. S. Oladipo et al, [2013]). Several studies have been conducted on the age,sex,and racial or ethnic groups in <a target="_blank" rel="nofollow" href="https://www.modishproject.com/breed-age-sex-growth-haematological-serum/">different geographical zones (O. Joy et al, [2009]</a>, G. S. Oladipo et al, [2009], G. S. Oladipo et al, [2013], I. P. Singh and N. K. Bharin, [1968], E. A. Osunwoke et al, [2012]).These authors have sited various categories of cranium on the basis of head length, breadth, and index and described seven groups of crania. R. F. Okupe et al. (1984), in a comparative study of bi parietal diameter (BPD) fetuses of some of the Nigerian ethnic groups and Caucasians, showed statistically significant differences until near term when the Nigerian fetuses showed <a target="_blank" rel="nofollow" href="https://www.modishproject.com/cultural-analysis-security-ethnic/">consistently longer BPD</a>. Cussenot et al. (1990) reported that skeletal measurements were made as the basis of foetal anthropometry and age determination. In a related study, cephalic index varied with advancing gestational age with the highest and lowest being 81.5 and 78.0 at weeks 14 and 28, respectively (D. L. Gray, 1989).</p><p><a target="_blank" rel="nofollow" href="https://www.modishproject.com/investigation-influence-prevalence-poultry/">Several studies</a>&nbsp;have been carried out to classify head shapes based on cephalic index into four internationally acceptable categories that include dolicocephalic (&lt;74.9), mesocephalic (75–79.9), brachycephalic (80.0–84.9), and hyperbrachycephalic (85.0–89.9) (P. Williams et al, [2003], M. Del Sol, [2005]). A study has shown that the people of Gurung community of Nepal of India are brachycephalic with cephalic index of 80.42 (G. V. Shah and H. R. Jahhav 2004). Bhils and Barelas are mesocephalic (76.98 &amp; 79.80) (I. Bhargava and G. A. Kher, [1960], I. Bhargava and G. A. Kher[1961]). The Iranian people are predominantly <a target="_blank" rel="nofollow" href="https://www.modishproject.com/impact-nigerian-national-theater-vehicle/">brachycephalic and hyper brachycephalic</a>&nbsp;(M.J.Golalipour, 2006). Besides being a <a target="_blank" rel="nofollow" href="https://www.modishproject.com/language-culture-tool/">predictor of fetal death</a>, early trans-vaginal measurement of cephalic index had been used for the determination of Down syndrome foetuses (P. Rosati and L. Guariglia 1999). The first classification based on cranial morphology is attributed to the professor of anatomy Anders Retzius (1840)</p> <br><p></p>
