Population affinities of Parsis in the Indian subcontinent

The present study was an attempt to document changes in frequencies of dental morphology traits and understand phenetic affinities of Parsis, who migrated to the Indian subcontinent around the 8th century. Despite successfully integrating themselves into the Indian society, they have retained their ethnicity and distinct cultural practices. This study was conceived as a result of an excavation at the site of Sanjan, Gujarat which, as per historical records, is believed to be the first town in the Indian subcontinent with a large Parsi settlement thereby facilitating a diachronic comparison between the ancestral and extant Parsi groups. We compared and analysed dental traits between the two groups expecting a very close relationship between them owing to their ancestor–descendent relationship. Eleven discrete dental traits were selected and scored using the Arizona State University Dental Anthropology System (ASUDAS). Frequency changes were assessed by comparing trait frequencies; whereas phenetic affinity between Parsis was assessed by statistically comparing them with 13 populations using Smith's mean measure of divergence (MMD) statistic. Comparison of dental trait frequencies between Sanjan and extant Parsi samples show significant differences in incisor morphology, Carabelli cusp and Hypocone development. Trait frequencies, MMD values and 2D multidimensional scaling (MDS) plot indicate that extant Parsis and Sanjan samples are distantly separated from each other. Extant Parsis show closer affinity to low caste Mahars and tribal Madia Gonds than South and Central Asian groups. Sanjan is distant from all other groups including extant Parsis. It is likely that genetic drift accentuated by their small numbers and strict endogamy has resulted in divergence of Parsi groups. Similarly, their convergence with Maharashtran groups indicates admixture of Parsis with local groups, which supports earlier conducted mtDNA studies. Copyright © 2009 John Wiley & Sons, Ltd.     

Cultural Changes in Funeral Rites During the Neolithic in the Northeast of the Iberian Peninsula? The Cave of Pantà de Foix (Barcelona)

During the third millennia bc , there is a change in the funerary patterns of the populations in Catalonia. This novelty usually has been usually related to a change in the economical source of the human groups that become less sedentary as the stockbreeding becomes more important. In the present study, we analyse this change, reflected in the mortuary practices, by the study of diet and health markers such as caries, dental calculus or enamel hypoplasias and of biological affinities based on dental non‐metric traits. It has been included a total amount of 317 permanent teeth from Cova del Pantà de Foix sites, a sepulchral cave found at the south‐west of the city of Barcelona and dates from the third millennia bc . The 74.2% of them present dental calculus deposits, which are usually related to a high protein intake. Nevertheless, the high prevalence of carious lesions (15.3% of the teeth) suggests that the main dietary contribution comes from carbohydrates. Furthermore, when this group is compared with one from the Middle Neolithic Age, which presents a lower calculus prevalence, no biological differences are observed. This lack of differences among these groups denote that the origin of the high amount of calculus deposit is environmental, which is consistent with the elevated observation of hypoplasias of the crown enamel. The absence of dietary, biological and economical differences indicates that the population substrate during the Neolithic in Catalonia is the same and that the transition in the funerary rite is related to a substantial change only regarding to mortuary practices.
