Anthropometry and the biological structure of the Hvar population.

Biological structure of the population of the island of Hvar was investigated by using the data on anthropometric variation among nine village populations; 24 body and 14 head dimensions were analysed from 487 male and 437 female adult subjects. Univariate and multivariate analyses revealed heterogeneity among the populations, which says much for the strength of the isolating factors on the island. Using correlations of anthropometric and geographic distance, the observed patterns of variation among villages were closely related to geography, suggesting migration to be an important factor in the formation of the island's population structure. Populations of the examined villages were further grouped to form the population of the eastern part and the population of the western part of the island, which have an ethnodemographic and sociocultural basis. The analyses revealed heterogeneity between the populations and thus provided evidence to support the hypothesis about the existence of the genetically different groups living in the same biotope.
