Human herpes simplex virus 1 (HSV-1), a life-long infection spread by oral contact, infects a majority of adults globally. Phylogeographic clustering of sampled diversity into European, pan-Eurasian, and African groups has suggested the virus codiverged with human migrations out of Africa, although a much younger origin has also been proposed. We present three full ancient European HSV-1 genomes and one partial genome, dating from the 3rd to 17th century CE, sequenced to up to 9.5× with paired human genomes up to 10.16×. Considering a dataset of modern and ancient genomes, we apply phylogenetic methods to estimate the age of sampled modern Eurasian HSV-1 diversity to 4.68 (3.87 to 5.65) ka. Extrapolation of estimated rates to a global dataset points to the age of extant sampled HSV-1 as 5.29 (4.60 to 6.12) ka, suggesting HSV-1 lineage replacement coinciding with the late Neolithic period and following Bronze Age migrations.

Background The human pathogen Haemophilus influenzae was the main cause of bacterial meningitis in children and a major cause of worldwide infant mortality before the introduction of a vaccine in the 1980s. Although the occurrence of serotype b (Hib), the most virulent type of H. influenzae, has since decreased, reports of infections with other serotypes and non-typeable strains are on the rise. While non-typeable strains have been studied in-depth, very little is known of the pathogen’s evolutionary history, and no genomes dating prior to 1940 were available. Results We describe a Hib genome isolated from a 6-year-old Anglo-Saxon plague victim, from approximately 540 to 550 CE, Edix Hill, England, showing signs of invasive infection on its skeleton. We find that the genome clusters in phylogenetic division II with Hib strain NCTC8468, which also caused invasive disease. While the virulence profile of our genome was distinct, its genomic similarity to NCTC8468 points to mostly clonal evolution of the clade since the 6th century. We also reconstruct a partial Yersinia pestis genome, which is likely identical to a published first plague pandemic genome of Edix Hill. Conclusions Our study presents the earliest genomic evidence for H. influenzae, points to the potential presence of larger genomic diversity in the phylogenetic division II serotype b clade in the past, and allows the first insights into the evolutionary history of this major human pathogen. The identification of both plague and Hib opens questions on the effect of plague in immunocompromised individuals already affected by infectious diseases.

What is osteobiography good for? The last generation of archaeologists fought to overcome the traditional assumption that archaeology is merely ancillary to history, a substitute to be used when written sources are defective; it is now widely acknowledged that material histories and textual histories tell equally valid and complementary stories about the past. Yet the traditional assumption hangs on implicitly in biography: osteobiography is used to fill the gaps in the textual record rather than as a primary source in its own right. In this article we compare the textual biographies and material biographies of two thirteenth-century townsfolk from medieval England-Robert Curteis, attested in legal records, and "Feature 958," excavated archaeologically and studied osteobiographically. As the former shows, textual biographies of ordinary people mostly reveal a few traces of financial or legal transactions. Interpreting these traces, in fact, implicitly presumes a history of the body. Osteobiography reveals a different kind of history, the history of the body as a locus of appearance and social identity, work, health and experience. For all but a few textually rich individuals, osteobiography provides a fuller and more human biography. Moreover, textual visibility is deeply biased by class and gender; osteobiography offers particular promise for Marxist and feminist understandings of the past. ¿Para qué sirve la osteobiografía? La última generación de arqueólogos luchó para superar la suposición tradicional de que la arqueología es meramente (accesoria) a la historia, una sustituta que se puede utilizar cuando las fuentes escritas son deficientes. Ahora es ampliamente reconocido que las historias materiales y las historias textuales igualmente válido y complementario del pasado. Sin embargo, la suposición tradicional continúa implícitamente en la biografía: se utiliza la osteobiografía para llenar los vacíos en el historial textual en vez de utilizarla como fuente primaria por derecho propio. En esta investigación comparamos las biografías textuales y biografías materiales de dos ciudadanos de la Inglaterra medieval del siglo XIII-Robert Cuteis, documentado en registros legales, y "Feature 958", excavada arqueologicamente y examinada osteobiograficamente. Como demuestra la primera, biografías textuales de la gente común sobre todo revelan algunos rastros de transacciones financieras o legales. La interpretación de estos rastros de hecho presume implícitamente una historia del cuerpo. La osteobiografía revela una clase de historia distinta, la historia del cuerpo como un sitio que contiene información sobre apariencia e identidad social, trabajo, salud y experiencia. Para todos aparte de algunos
