Population structure analysis utilization of anthropometric and physiological raits

Population structure of the Eastern Adriatic island region has been extensively analysed using different biological and sociocultural variables. In this study, athropometric (head and body) and physiological (cardiorespiratory) data from 8 rural communities on the island of Korčula were used and analysed together with genetic, migrational kinship, linguistic, and geographical data, to further explore the interaction of biological, historical, and sociological factors in small isolated populations. A comparison of morphology and physiology on the ecologically uniform island provides a good example of the balance that occurs in microevolution between selective pressures toward homogenization and selective inertia toward heterogeneity. Head variables, being more eco-stable than body and cardiorespiratory variables, remain relatively more different between two distinct, east and west, populations than do more eco-labile body and physiological variables, although they all vary significantly between east and west. These east-west contrasts correspond with recorded history of the settlement and movement of the population onto and across the island. In addition to the regional differences, significant morhological and physiological variation exists among all village populations that correlates with geographic and linguistic distances. This is an indication of the considerable isolation that has persisted between the villages until recently.
