AbstractRelatively little is known about Nubia’s genetic landscape prior to the influence of the Islamic migrations that began in the late 1st millennium CE. Here, we increase the number of ancient individuals with genome-level data from the Nile Valley from three to 69, reporting data for 66 individuals from two cemeteries at the Christian Period (~650–1000 CE) site of Kulubnarti, where multiple lines of evidence suggest social stratification. The Kulubnarti Nubians had ~43% Nilotic-related ancestry (individual variation between ~36–54%) with the remaining ancestry consistent with being  introduced through Egypt and ultimately deriving from an ancestry pool like that found in the Bronze and Iron Age Levant. The Kulubnarti gene pool – shaped over a millennium – harbors disproportionately female-associated West Eurasian-related ancestry. Genetic similarity among individuals from the two cemeteries supports a hypothesis of social division without genetic distinction. Seven pairs of inter-cemetery relatives suggest fluidity between cemetery groups. Present-day Nubians are not directly descended from the Kulubnarti Nubians, attesting to additional genetic input since the Christian Period.

The Impact

Nubia has been a corridor for the movement of goods, culture, and people between sub-Saharan Africa, Egypt, and West Eurasia since prehistory, but little is known about the genetic landscape of the region prior to the influence of the Islamic migrations that began in the late 1st millennium CE. We report genome-wide data for 66 individuals from the site of Kulubnarti (∼650–1000 CE), increasing the number of ancient individuals with genome-level data from the Nile Valley from three to 69. Our results shed light on the genetic ancestry of a Christian Period group and help to address a long-standing question about the relationships among people buried in two neighboring cemeteries who show skeletal evidence of differences in morbidity and mortality that are broadly suggestive of differences in social status. We find that the Kulubnarti Nubians were admixed with ∼43% Nilotic-related ancestry on average (individual proportions varied between ∼36-54%) and the remaining ancestry reflecting a West Eurasian-related gene pool likely introduced into Nubia through Egypt, but ultimately deriving from an ancestry pool like that found in the Bronze and Iron Age Levant. The admixed ancestry at Kulubnarti reflects interactions between genetically-distinct people in northeast Africa spanning almost a millennium, with West Eurasian ancestry disproportionately associated with females, highlighting the impact of female mobility in this region. We find no significant differences in ancestry among individuals from the two plausibly socially-stratified cemeteries at Kulubnarti, supporting hypotheses that the groups may have been socially divided but were not genetically distinct. We identify seven pairs of inter-cemetery relatives as close as second-degree, suggesting that any social divisions at Kulubnarti did not prevent mixing between groups. Present-day Nubians are not directly descended from the Christian Period people from Kulubnarti without additional admixture, attesting to the dynamic history of interaction that continues to shape the cultural and genetic landscape of Nubia.

Motivated Social Cognition

This study proposes that monuments are technologies through which communities think. I draw on conceptual blending theory as articulated by Mark Turner and Gilles Fauconnier to argue that monuments are material anchors for conceptual integration networks. The network model highlights that monuments are embedded in specific spatial and socio-historical contexts while also emphasizing that they function relationally by engaging the imaginations of communities. An enactivist understanding of these networks helps to explain the generative power of monuments as well as how they can become dynamic and polysemic. By proposing a cognitive scientific model for such relational qualities, this approach also has the advantage of making them more easily quantifiable. I present a test case of monumental installations from the Iron Age Levant (the ceremonial plaza of Karkamiš) to develop this approach and demonstrate its explanatory power. I contend that the theory and methods introduced here can make future accounts of monuments more precise while also opening up new avenues of research into monuments as a technology of motivated social cognition that is enacted on a community-scale.

The Bronze Age

“China” here designates much but not all of China Proper or Inner China, terrain controlled during the Imperial era (221 bce to ce 1912) by historic dynastic states. Vast regions to the northeast, north, and west—Manchuria, Mongolia, Xinjiang, and Tibet—are excluded even though they are now integral to the modern-day nation-state. Similarly, we slight areas of the south, for example the modern-day Lingnan and Yun-Gui macroregions, that only gradually were absorbed after the Bronze Age. In Chinese scholarship, “Bronze Age” (qingtong shidai青铜时代) serves as an alternate for the “Three Dynasties” (san dai三代) of traditional historiography: Xia (Hsia), Shang, and Zhou (Chou). Bracketing dates of c. 2000–221 bce are now widely used, the first an approximation, the latter firm. Bronze alloy, however, was just one ingredient of material cultures of the Three Dynasties. Other features include the appearance of states, social stratification, urbanization, warfare, and the appearance of iron (the Iron Age), in addition to achievements in literature, music, and philosophy during the latter centuries, a kind of “Classical Age.” Today, “arts” may encompass many forms of crafting materials for a variety of purposes and audiences. This bibliography specifically addresses architecture, bronze, jade, lacquer, and silk as well as music, pictorial representation, and writing. A term from the Bronze Age—“Six Arts” (or “skills,” liu yi六艺)—defined expertise for an elite male as ritual, music, archery, chariot driving, writing, and calculation. While the overlap between the ancient and modern categories is at best partial, these concepts do intersect in terms of makers and consumers and in social and religious purposes. The elite’s luxury lifestyle was sustained by the “arts.” Ritual required bronze vessels, and the requisite music was performed on instruments of bronze, stone, lacquer, etc. Chariots were outfitted with bronze; writing and picturing employed silk. This bibliography emphasizes Chinese archaeology, both as a discipline and as a realm of knowledge that have burgeoned since the late 20th century. Archaeology creates fresh evidence, which then becomes the stuff of excavation reports, investigative scholarship, exhibitions and museum displays, and reference works. Only some of this bounty can be cited here, and readers are directed to Oxford Bibliographies for Chinese Studies (e.g., Chinese Architecture, Calligraphy, Ceramics, Paleography, Ancient Chinese Religion) for further advice. This essay is limited to publications from 1980 and, when possible, favors English-language sources.

An important missing piece in the puzzle of how plastids spread across the eukaryotic tree of life is a robust evolutionary framework for the host lineages. Four assemblages are known to harbour plastids derived from red algae and, according to the controversial chromalveolate hypothesis, these all share a common ancestry. Phylogenomic analyses have consistently shown that stramenopiles and alveolates are closely related, but haptophytes and cryptophytes remain contentious; they have been proposed to branch together with several heterotrophic groups in the newly erected Hacrobia. Here, we tested this question by producing a large expressed sequence tag dataset for the katablepharid Roombia truncata , one of the last hacrobian lineages for which genome-level data are unavailable, and combined this dataset with the recently completed genome of the cryptophyte Guillardia theta to build an alignment composed of 258 genes. Our analyses strongly support haptophytes as sister to the SAR group, possibly together with telonemids and centrohelids. We also confirmed the common origin of katablepharids and cryptophytes, but these lineages were not related to other hacrobians; instead, they branch with plants. Our study resolves the evolutionary position of haptophytes, an ecologically critical component of the oceans, and proposes a new hypothesis for the origin of cryptophytes.

Iron Age Levant

The Bayesian model presented in this article is the first attempt to produce a chronological framework for the Iron Age in the Levant, using radiocarbon dating alone. The model derives from 339 determinations on 142 samples taken from 38 strata at 18 sites. The framework proposes six ceramic phases and six transitions which cover c. 400 years, between the late twelfth and mid eighth centuries BC. It furnishes us with a new scientific backbone for the history of Iron Age Levant.The article is supported by an online supplement which can be found in at http://antiquity.ac.uk/projgall/finkelstein324

The Cost

Abstract The precipitous drop in the cost of genomic sequencing and the concomitant availability of computational methods for comparing genome-level data has made the accurate taxonomic placement of bacteria affordable and relatively rapid. Inaccurate taxonomic placement of bacteria has serious implications in clinical, environmental, and regulatory microbiology, but it can also adversely affect interpretation of research results. The quorum biosensor strain CV026 was derived from an isolate of Chromobacterium that was labeled as C. violaceum ATCC 31532, and is catalogued by the ATCC under that species. Nearly 200 papers have been published that use CV026 as an indicator for quorum sensing activity in many Gram negative bacteria, but the inability of C. violaceum strains to complement the quorum sensing mutation in CV026 has called the taxonomic placement of the parent strain into question. We used molecular phylogeny and a large number of metabolic and phenotypic characters to demonstrate that Chromobacterium strain ATCC 31532 is a member of species Chromobacterium subtsugae.

First Time

The geographical location and shape of Apulia, a narrow land stretching out in the sea at the South of Italy, made this region a Mediterranean crossroads connecting Western Europe and the Balkans. Such movements culminated at the beginning of the Iron Age with the Iapygian civilization which consisted of three cultures: Peucetians, Messapians and Daunians. Among them, the Daunians left a peculiar cultural heritage, with one-of-a-kind stelae and pottery, but, despite the extensive archaeological literature, their origin has been lost to time. In order to shed light on this and to provide a genetic picture of Iron Age Southern Italy, we collected and sequenced human remains from three archaeological sites geographically located in Northern Apulia (the area historically inhabited by Daunians) and radiocarbon dated between 1157 and 275 calBCE. We find that Iron Age Apulian samples are still distant from the genetic variability of modern-day Apulians, they show a remarkable genetic heterogeneity, even though a few kilometers and centuries separate them, and they are well inserted into the Iron Age Pan-Mediterranean genetic landscape. Our study provides for the first time a window on the genetic make-up of pre-imperial Southern Italy, whose increasing connectivity within the Mediterranean landscape, would have contributed to laying the foundation for modern genetic variability. In this light, the genetic profile of Daunians may be compatible with an autochthonous origin, with plausible contributions from the Balkan peninsula.

Modern Nation State

This book presents a new model for the kingdoms that clustered around the northeast corner of the Mediterranean Sea during the Iron Age, ca. 1200–600 BCE. Rather than presenting them as an ancient version of the modern nation-state, characterized by homogenous ethnolinguistic communities like “the Aramaeans” or “the Luwians” living in neatly bounded territories, this book presents these polities as being fundamentally diverse and variable, distinguished by demographic fluidity and cultural mobility. This conclusion is reached via an examination of a host of evidentiary sources, including site plans, settlement patterns, visual arts, and historical sources. Together, these lines of evidence lead to the awareness that this time and place consisted of a complex fusion of cultural traditions that is nevertheless distinctly recognizable unto itself. This book thus proposes a new term to encapsulate that diversity: the Syro-Anatolian Culture Complex.
