Mitochondrial DNA HVRI variation in Balearic populations.

The Balearic archipelago (Majorca, Minorca, and Ibiza islands and the Chuetas, a small and inbred community of descendants of Sephardic Jews) and Valencia were studied by means of the sequencing of a 404-bp segment of hypervariable region I (HVRI) mtDNA in 231 individuals. In total, 127 different haplotypes defined by 92 variable positions were identified. The incidence of unique haplotypes was very low, especially in Ibiza and the Chuetas. A remarkable observation in the Chueta community was the high frequency (23%) of preHV-1, a Middle Eastern lineage that is closely related, though not identical, to many others found at high frequencies in different Jewish populations. The presence of this haplogroup convincingly supported the Jewish origin of the Chueta community. The studied populations showed a reduced African contribution, and no individuals were detected with North African haplogroup U6, indicating a lack of maternal contribution from the Moslem settlement to these populations. Only Ibiza showed a lower diversity, indicating a possible genetic drift effect, also supported by the historical information known about this island. The variability in the sequence of mtDNA hypervariable region I correlated well with the existing information from the populations, with the exception of that of the Y-chromosome, which could indicate a differential contribution of the maternal and paternal lineages to the genetic pool of the Balearic Islands. The phylogenetic trees showed the intermediate position of the Chueta population between the Middle Eastern and Majorcan samples, confirming the Jewish origin of this population and their Spanish admixture.

Research trends in human osteology: a content analysis of papers published in the American Journal of Physical Anthropology.

This paper explores recent research trends in human osteology, based on articles published in the American Journal of Physical Anthropology (AJPA) during two 5-year intervals: 1980--1984 and 1996--2000. Topical "visibility" is measured in terms of article counts; "impact" is estimated through citation indices. Our results indicate that human osteologists continue to publish a range of methodological, analytical, and descriptive research papers that address a broad array of subjects. Analytical articles are cited more frequently than descriptive articles and thus have higher impact, reflecting the discipline's continued commitment to problem-oriented research. Differences in publication patterns exist between scholars during early and later stages of their careers. Articles published by students and Ph.D.s within 2 years of their doctoral degree are more frequently descriptive than analytical, when compared to people with longer career histories. Topics such as pathology, forensic anthropology, and biodistance modeling remain highly visible, while articles on the dentition have waned. An increase in functional research directed toward the postcranial skeleton is also reflected in our data. While continued visibility for morphological investigations is apparent, the impact of recently developed applications in bone chemistry and molecular anthropology is amply documented in our data, particularly during the more recent survey years.
