We report a molecular methodology to obtain and analyse ancient bacterial DNA from archaeological dental calculus. Recent and archaeological DNA samples, as old as 4000 bp , were successfully extracted and amplified with species‐specific PCR primers. We propose this approach in order to: detect the presence of specific bacterial species infecting past human populations; compare the composition of ancient oral microbiomes among human populations; and analyse the genetic variability and covariation of bacteria and human host populations. Genomic analysis of bacteria from dental calculus is a promising source of evidence for palaeopathological and micro‐evolutionary studies, focused either on micro‐organisms or their human hosts. 相似文献

The remnant of once-famous “London Stone” stands almost unnoticed today in Cannon Street, in the City of London. Speculation about its origin began as early as the sixteenth century. This paper considers in particular the identification of the Stone as London's talisman (a view embodied in an invented “ancient saying” that linked it to the city's legendary Trojan foundation), or as a prehistoric “fetish stone” set up when London was first settled. The mythologising of London Stone continues, and at the turn of the twenty-first century it is regarded by some as an essential element in London's indefinable “sacred geometry.” 相似文献

Qualitative, quantitative and distributional aspects of the overall results from archaeological surveillance of the routes before and during construction of the M4 and M5 motorways in Wiltshire, Gloucestershire and Somerset are discussed. By comparing the data from the M4 and M5, and from the M40 in Oxfordshire too, some elements of numerical consistency are adduced for which explanations are sought rather than provided. An implication is that, despite the circumstances of their recovery, archaeological data from motorways are, in bulk, not without significance for the lowland English landscape. 相似文献

The Germans from Russia are a prominent settlement group in the rural landscape of Saskatchewan. Perhaps because they came incrementally, by chain migration, rather than by organized group colonization, they compose an ethnic group little noticed by historians. Also, their immediate origins are divided, inasmuch as earlier German-Russian immigrants came directly from Russia, whereas many twentieth-century German-Russian immigrants came to Canada from the United States, mainly from North Dakota and South Dakota. This article offers the first focused, scholarly historical treatment of German-Russian immigration and life in Saskatchewan. Drawing on oral histories collected with the support of the Faculty Research Program of the Canadian Embassy, it focuses particularly on growing up German-Russian on the prairies, positing a German-Russian ethnic identity distinct both from neighbor immigrant groups in Saskatchewan and from origin communities in the United States. 相似文献

The arrival of Europeans in the New World had profound and long-lasting results for the native peoples. The record for the impact of this fundamental change in culture, society, and biology of Native Americans is well documented historically. This paper reviews the biological impact of the arrival of Europeans on native populations via the study of pre- and postcontact skeletal remains in Spanish Florida, the region today represented by coastal Georgia and northern Florida. The postcontact skeletal series, mostly drawn from Roman Catholic mission sites, are among the most comprehensive in the Americas, providing a compelling picture of adaptation and stress in this setting. Study of paleopathology, dental and skeletal indicators of physiological stress, stable isotope (carbon and nitrogen) analysis, tooth microwear, and skeletal morphology (cross-sectional geometry) reveals major alterations in quality of life and lifestyle. The bioarchaeological record indicates a general deterioration in health, declining dietary diversity and nutritional quality, and increasing workload in the contact period. The impact of contact in Spanish Florida appears to have been more dramatic in comparison with other regions, which likely reflects the different nature of contact relations in this setting versus other areas (e.g., New England, New France). The bioarchaeological record represents an important information source for understanding the dynamics of biocultural change resulting from colonization and conquest. 相似文献

Models to investigate categorical data can be divided into preprocessing, limited parameterization, and formal logit models. To illustrate the advantages of preprocessing and limited parameterization models they are applied to a data set of tenure and type of housing choice before the data are examined with hierarchical logit and nested logit models. The preprocessing approaches are useful in selecting optimal subsets of independent variables with respect to the dependent variable. The ease of application and interpretation of a limited parameterization approach extends the clarity of the results from the preprocessing approaches. Because some variables are only relevant at specific levels of other independent variables, nonstandard (nested) logit models are necessary to understand the nested relationships. 相似文献

The history of research into the Middle Stone Age of East Africa and the present state of knowledge of this time period is examined for the region as a whole, with special reference to paleoenvironments. The known MSA sites and occurrences are discussed region by region and attempts are made to fit them into a more precise chronological framework and to assess their cultural affinities. The conclusion is reached that the Middle Stone Age lasted for some 150,000 years but considerably more systematic and in-depth research is needed into this time period, which is now perceived as of great significance since it appears to span the time of the evolution of anatomically Modern humans in the continent, perhaps in East Africa. 相似文献
