Dating of modified femora of extinct dwarf Hippopotamus from Southern Madagascar: Implications for constraining human colonization and vertebrate extinction events

Two significant events in the late Holocene history of Madagascar were (a) the arrival of people, and (b) the loss of nearly two dozen species of land vertebrates in the socalled “subfossil extinctions”. The consensus is that the faunal losses occurred shortly subsequent to human arrival, but the timing of these events is poorly constrained. The minimum age for initial human presence on the island may now be set at approximately 2000 bp, on the basis of AMS ¹⁴C dates for human-modified femora of extinct dwarf hippos from SW Madagascar. Assuming that this date also marks the beginning of deleterious human interactions with the subfossil fauna, and assuming that this fauna became completely extinct by 900 bp, the width of the anthropogenic “extinction window” may have been as long as c. 1000 a. This estimate, nearly twice the length of previous ones, is close to the unadjusted minimum for the duration of the terminal Pleistocene extinction event in the Americas. Whether or not this length of time comports with theoretical expectations of a “blitzkrieg” pattern of losses is uncertain, but greater refinement in dating the end of the subfossil extinctions is unlikely to produce radically shorter estimates of duration.     

Early Cotswold woodland

Many “wold” names are derived from the OE wald, meaning “woodland”. In a recent paper Everitt examined the evidence for Kent and suggested that areas of wold downland had been wooded in the Anglo-Saxon period. They had also been territorially linked to river-estates as areas of outlying wood-pasture. The present paper examines the evidence for the Cotswolds. Here the name “wold” is applied to an area which was largely open pasture by the medieval period and the use of the term in its later sense of “high, open country” would not have been out of place. Yet the evidence from early place-names and pre-Conquest charters suggests that a great deal of woodland was present in the Anglo-Saxon period, especially in the valleys dissecting the escarpment and along the scarp face. Although this was a watershed area, divided between adjacent valley-based estates, as in Kent, there is little direct evidence here of an early interest in woodland-pasture. The importance of the area seems to have arisen in the middle and later Anglo-Saxon period as a result of an increased use of the upland for sheep pasture. Nevertheless, the term “wold” seems to date from an earlier period when woodland was indeed extensive.     

Geographies of Hardy's Wessex

The novels of Thomas Hardy represent a number of different “geographies”—the means by which their various characters and narrators explore places and come to know them. The “geographies” of the characters and narrators in Tess of the d'Urbervilles and The return of the native are examined in this essay. It shows that the “primal” geography of the youthful Tess, and of those who live on Egdon Heath, is represented as circular, and is constructed by more senses than the visual, while that of the reader is linear and wholly visual in its preoccupations with geology, cartography and the picturesque; and it examines the destruction of the “primal” geography in Tess, as she becomes an itinerant labourer. The task of the narrators, in their attempt to mediate between the two geographies, is considered, and it is suggested that this attempt is bound to fail, because the division between them is founded in an idea of history, as of a moment of primal unity and its subsequent differentiation, which is not perceived as open to question.     

A system for classification and description of the horn cores of cattle from archaeological sites

A system is proposed for the classification and sexing of the horn cores of cattle recovered from archaeological sites. The cores are first divided into four groups depending on their length. The terms “small”, “short”, “medium” and “long horned” are given to these groups but bear no relation to the names used for modern breeds of cattle. After differentiation according to length, the sex of the core is designated by visual appraisal of the shape, curvature and angle of attachment of the cores to the frontal bones. It is not claimed that the sex of individual horn cores can always be established but from the sample of 80 cores that we tested by statistical analysis (presented in an appendix) it was evident that the categories based on length and assessment of sex did separate out as expected.     

The limits of biomolecular palaeopathology: ancient DNA cannot be used to study venereal syphilis

To determine whether ancient DNA (aDNA) can be used to study the palaeopathology of venereal syphilis, we carried out a comprehensive analysis of the preservation of human and pathogen DNA in a set of 46 bones of various ages, most of which displayed osteological indications of the disease. Bones came from seven English cemetery sites that were in use during the 9th–19th centuries. Twelve of the 46 bones consistently yielded mitochondrial DNA (mtDNA) sequences after replicate polymerase chain reactions (PCRs), and a further 13 bones yielded mtDNA sequences with less reproducibility. The sequence data enabled tentative mitochondrial haplogroups to be assigned to nine of the bones, and the identities and frequencies of these haplogroups were compatible with the geographical origins of the bones. Twenty-one bones consistently gave negative results with all mtDNA PCRs, indicating that at least these bones were not contaminated with modern human DNA, and those bones that gave positive results only yielded one sequence each, again suggesting that widespread modern contamination had not occurred. Mycobacterium tuberculosis sequences were obtained from seven bones, including three of five bones with tuberculous lesions. The cloned and direct sequences obtained from both the mtDNA and M. tuberculosis PCR products showed features typical of degraded aDNA. All of these results suggest that at least some of the 46 bones that we studied were suitable for aDNA analysis. All 46 bones were tested with nine different treponemal PCRs, each optimised to give a detection limit of ≤5 genomes. Although various bones gave PCR products of the expected size with one or more of these PCRs, sequencing showed that none of these products were authentic treponemal amplicons. Our failure to detect treponemal DNA in bones that were suitable for aDNA analysis, using highly sensitive PCRs, suggests that treponemal DNA is not preserved in human bone and that it is therefore not possible to use aDNA analysis to study venereal syphilis. Any past or future paper claiming detection of treponemal aDNA should therefore be accompanied by a detailed justification of the results.     

Beyond Boundaries: Nature,Culture and a Holistic Approach to Domestication in the Levant

The main objective of this paper is to suggest an alternative approach for the investigation of domestication in the Levant. First, basic data regarding domestication in the Levant are presented. Then the various traditional approaches towards domestication in the prehistoric Levant, labeled (1) environmental, (2) social and anthropological, and (3) cognitive, are briefly reviewed. This discussion forms the basis for a proposal of a “holistic approach,” in which domestication is regarded as a long-term, multidimensional and multirelational phenomenon, including many elements—such as plants, animals, humans, material culture and ancestors—with increasing human manipulation of these various constituents. After a presentation of the theoretical framework, a growth metaphor is used to reconstruct the process of domestication (ca. 20,000–6500 B.P.) as a number of phases: (1) germination in the Kebaran; (2) development in the Early Natufian; (3) retreat/dormancy in the Late/Final Natufian; (4) growth in the Pre-Pottery Neolithic A; (5) florescence in the Early- and Middle Pre-Pottery Neolithic B: (6) further development in the Late Pre-Pottery Neolithic B; (7) dispersal in the Final Pre-Pottery Neolithic B and the Pottery Neolithic. In each of these phases, relations between the various elements are dealt with, special attention being paid to symbolical relations, as evidenced by “art” and ritual.     

Droughts as random events in the Maya lowlands

Because the values of most of the parameters controlling the occurrence and severity of a drought in a given location are unknown, and no periodicity has been observed, droughts can be considered random events. Running a random number generator within the limits of the annual rainfall variability relevant to the Maya lowlands, and defining a “Lean Year”, it is observed that strings of lean years occur quite frequently. Defining “Severe Drought”, “Disaster”, and “Catastrophe” based on the length of these strings, it is observed that a severe drought occurs on average every 32 years, a disaster occurs on average every 130 years, and a catastrophe on average every 500 years. These values fit the measured variability of the Yucatan climate, as observed in lake core sediments and in the post conquest written records. It also fits the average occurrence of “megadroughts” in the US Great Plains.The fit between the random occurrence model and the actual, “measured” occurrence of droughts supports the notion that for all practical purposes, droughts had been random events in the Maya region and could not be predicted. The lack of evident periodicity could be one of the reasons why means for long-term storage of food products were not developed there. It may also have affected the relationship between the priesthood and the general populace in that region.Since the method described here can be applied to any climatic region once the rainfall variability and the sensitivity of the local agriculture are known or can be estimated, if similar results are found they may probably have affected other regions with other ancient cultures in a similar way.     

Improved methodology for extraction and amplification of DNA from single grains of charred wheat

Comparisons were made between two commonly used methods for the extraction of ancient DNA from charred plant remains. Using artificially charred wheat seeds, we show that silica-binding is the most efficient method for extraction of DNA. We describe a improved silica-binding procedure, including pre-incubation with N-phenacylthiazolium bromide and increased washing of bound DNA, which yields amplifiable DNA from seeds heated at 200 °C for up to 8 h, conditions which promote the formation of Maillard products which often copurify with aDNA and inhibit subsequent PCRs. We believe that this method will be effective in ancient DNA extraction with most types of charred archaeobotanical material. Both cold- and hot-start PCR procedures gave good amplicon yields with extracts prepared in this way, but cold-start PCRs also resulted in synthesis of short artefact products. Addition of bovine serum albumin to PCRs, an inert carrier substance thought to enhance amplification efficiency by binding contaminants, had no advantageous effect and in fact reduced amplicon synthesis.     

An improved PCR method for endogenous DNA retrieval in contaminated Neandertal samples based on the use of blocking primers

Neandertal skeletal remains are usually contaminated with modern human DNA derived from handling and washing of the specimens during excavation. Despite the fact that the distinct Neandertal haplotypes allow the design of specific primer pairs, for instance in most of the mitochondrial DNA (mtDNA) hypervariable region 1 (HVR1), the human contaminants can often outnumber the endogenous DNA, thus preventing a successful retrieval of Neandertal sequences. We have developed a novel PCR method, based on the use of blocking primers that preferentially bind to modern human contaminant DNA and block their amplification, and greatly improve the efficiency of Neandertal DNA retrieval. We tested the method in four El Sidrón Neandertal samples (two teeth and two bone fragments) with different contamination levels and taphonomic conditions, and we have been able to significantly increase the Neandertal yield from figures around 25.23% (5–69.6%) up to 90.18% (75.3–100%).     

A comparison of the treatment of errors in radiocarbon dating calibration methods

The application of radiocarbon dating to archaeological samples generally requires calibration of ¹⁴C dates to calendar ages and interpretation of dating errors. In this paper, four recent methods of age calibration are assessed, particularly with regard to their quality of error treatment. Recent experimental research has suggested that commonly quoted errors on “raw” ¹⁴C dates may require enlargement to more realistic levels, which, when incorporated in the calibration schemes, produce a considerable increase in the size of the typical calibrated interval. A general decrease in the sensitivity of ¹⁴C dating using single, “normal precision” dates is implied. Thus typical calibrated age intervals range from 300 to 1300 years (approximate 95% confidence level), with little improvement resulting if “high precision” calibration systems are used to correct “normal precision” dates. Of the four methods considered here, that proposed by Neftel is found to provide the most objective, flexible, comprehensive and “easy to use” scheme. This method is particularly recommended for its treatment of errors both on the dates to be calibrated and on the calibration curve itself.     

A Mediaeval Case of Lepromatous Leprosy from 13–14th Century Orkney, Scotland

Erosion in the 1960s resulted in exposure of human skeletal remains from a Norse Christian cemetery at Newark Bay, Orkney, Scotland. One set of remains showed osteological evidence of advanced lepromatous leprosy, but the absence of bones from the lower limbs precluded definitive diagnosis. The aim of the present study was to determine whether Mycobacterium leprae could be detected in bone extracts, as a means of confirming the diagnosis of leprosy. Bone samples were examined from the suspected leprosy case and from a second contemporary burial thought to be free of disease. DNA was amplified by polymerase chain reaction (PCR) using primers specific for a repetitive element (RLEP) characteristic of M. leprae. Additional PCR tests specific for Mycobacterium tuberculosis and for amelogenin (a human gene suitable for sex determination) were also applied to the samples. M. leprae DNA was detected only in the skull sample from the suspected leprosy case. The DNA sequence was identical to that found in present day isolates of M. leprae. Positive results were obtained only using a PCR reaction designed to amplify relatively short stretches of DNA (<175 bp), suggesting the microbial DNA had undergone extensive fragmentation. There was no evidence of M. tuberculosis DNA in bones from the leprosy suspect or control individual. The ability to recover ancient samples of DNA provides an opportunity to study long-term evolutionary changes that may affect the epidemiology of microbial pathogens.     

Lithostratigraphy of Border Cave, KwaZulu, South Africa: a Middle Stone Age sequence beginning c. 195,000 b.p.

Border Cave is well-known for its Middle Stone Age (MSA) sequence and associated hominids, as well as for the earliest demonstrable Later Stone Age (LSA) (c. 38,000 b.p.) strata in southern Africa. Detailed lithostratigraphic and sedimentological study permits identification of 8 Pleistocene sedimentary cycles, including 6 major cold phases and 2 intervening weathering horizons. The 2 youngest cold phases are associated with the LSA and have 8 ¹⁴C dates 38,600-13,300 b.p. By gauging sedimentation rates in finer and coarser sediments, duration of sedimentary breaks, and allowing for differential compaction, the excellent radiocarbon framework provided by 28 available ¹⁴C dates can be extrapolated to the 6 cold intervals and 2 palaeosols that are older than 50,000 b.p. These clearly span oxygenisotope stages 4, 5 and 6, placing the base of the MSA deposits at c. 195,000 b.p., Homo sapiens sapiens at c. 90,000–115,000 b.p. and the sophisticated, microlithic “Howieson's Poort” industry at 95,000 b.p. These results require radical reassessment of the age and nature of the MSA complex and of the earliest evolution of anatomically-modern people.     

Ancient DNA in human bones from Neolithic and Bronze Age sites in Greece and Crete

Attempts were made to detect ancient DNA (aDNA) in samples of 88 human skeletons from eight Neolithic and Bronze Age sites in Greece and Crete. Ancient DNA was absent in specimens from Nea Nikomedia, Lerna, Karaviádena (Zakro), Antron Grave Circle A and Mycenae Grave Circle A. For each of three skeletons from Antron Grave Circle B that were sampled, polymerase chain reactions (PCRs) gave products for nuclear but not mitochondrial DNA, but amplicon yield was low and inconsistent with replicate PCRs failing to give reproducible results. With specimens from Mycenae Grave Circle B, evidence for mitochondrial aDNA was obtained for four of the 22 skeletons that were studied, and at Kouphovouno evidence for mitochondrial and/or nuclear aDNA was obtained with eight of the 20 skeletons that were examined. We conclude that, although aDNA might be present in some Eastern Mediterranean skeletons from later centuries of the Bronze Age, it is not commonly found in material from this period and is likely to be absent from older material.     

Immigration, the internet, and spaces of politics

This paper examines the kinds of politics that are enabled by the Internet with respect to immigrants to the United States; its primary concern is whether the political spaces created through the Internet can foster incorporation of immigrants in the political community or whether the political activity on the Internet seems likely to lead to a more fractionalized political community in which the position of immigrants remains marginal. This exploration is based first on a random sample of web-sites about immigration and second on a more targeted sample of sites aimed specifically at two immigrant groups. The analysis of web-sites indicates that there is a great deal of information about immigrants on the Internet, and that most of it seems to be directed to service providers, policy makers, and researchers. There is relatively little discussion by or about immigrants, and beyond a few notable sites, there is almost no sign of mobilization. To the extent that the Internet is used to create new political spaces, it may not be spaces for deliberation and discussion. Rather, the political spaces seem to be informational spaces in which the politics are not easily or directly read.

The Internet is widely heralded as opening spaces for a wide variety of politics and political voices. But as it is praised for its inclusiveness, it is also pilloried for enabling the fragmentation of political opinion without providing a forum in which common political ground can be identified or consensus achieved. In the former view, the Internet fosters greater inclusion in democratic debate and political community. In the latter view, it contributes to a weakening of the bonds that are necessary for a political community to reach consensus and to provide guidance for democratic governance.Consider the examples in the epigraph to the paper. Al-Awda is a political movement devoted to securing the right of return for Palestinian refugees and their families. It organizes marches and demonstrations in cities across the US and Western Europe. One reason for the apparent mismatch between the locations of the “problem” and of the “action” is that many – though by no means all – of the participants in the marches are immigrants from the Middle East or they are of Arab descent. While the organization is based in Massachusetts, most of the mobilization through it occurs on-line, and it is not clear that there is either a permanent staff or regular meetings, other than the marches. Café Arabica provides a venue for discussion of a wide range of topics related to Arab culture and politics. Much like the romanticized café society, discussion can be lively and seems to include a wide range of participants and viewpoints. Café Arabica includes an on-line discussion forum, again with many of the participants apparently either being from the Middle East or the descendants of immigrants from the region. It labels itself as an Arab-American on-line community.These two web-sites were not chosen at random. They both relate to immigrants – social groups that are often not able to participate in political discussion and debate in their host countries. As such, these sites exemplify both the possibilities and the limitations that commentators have identified when they discuss the Internet and its role in fostering political dialogue. Some people would see these sites as signs of a group that wants to use the political process in one country to influence events in another country. Some people will read these sites as a an indication that at least one immigrant group – if not all immigrants – refuse assimilation, which is the basis of incorporation into the American political community. Still others will view these sites as attempts to incorporate a set of political voices and agents into a more inclusive political community. This paper examines the use of the Internet in political debate and mobilization around immigrants in the United States. It considers the nature of political discussion on the Internet and the agents involved in it. The overarching concern is whether the Internet fosters a more inclusive political community or whether it leads to alternative political spaces that remain unincorporated with respect to the political community of the host society.The paper is organized in four sections. The first provides a background for the debates about immigrants, the Internet, and politics. The second section is an overview of the theoretical debates about the public sphere as a political space in which members of a polity can participate and the ways in which the Internet may transform that space. The third section highlights some of the key issues that condition migrants’ acceptance into a polity, focusing primarily on the United States. With these sections serving as background, the final section of the paper explores political discussion on the Internet by and about immigrants. This exploration is based first on a random sample of web-sites about immigration and second on a more targeted sample of sites aimed specifically at two immigrant groups. The goal in these examinations is to evaluate the extent to which the Internet can provide the basis of a political space in which issues related to the incorporation of immigrants can be debated or whether it is a space that fosters a more fractionalized politics unlikely to lead to greater political incorporation of immigrants.     

Warrior geopolitics: Gladiator, Black Hawk Down and The Kingdom Of Heaven

The “war on terror” and remilitarization of political anxiety in the aftermath of September 11th in the West, is both facilitated and challenged by representations of geopolitical danger and the supposed necessity for warriors to fight wars in distant lands. Ridley Scott's three movies, Gladiator, Black Hawk Down and most recently The Kingdom of Heaven explore the morality and identity of warriors. They do so in exotic landscapes and settings that emphasize the confrontation with danger as external and frequently unknowable; political violence is presented as something that has both simple and very complicated geographies. The public discussion of the necessity for warfare and “intervention” in Western states is enmeshed in discourses of moralities, rights and “just war”. The professional Western warrior, whether a special forces operative or garrison soldier in peacekeeping mode, is a key figure of the post September 11th era, physically securing the West, and simultaneously securing its identity as the repository of virtue against barbaric threats to civilization. These themes are key to Ridley Scott's work. Analyzing them in terms of the warrior, empire and the particular geographies of combat adds a specifically military dimension to the critical geopolitical literature on war and representation.     

FOCUS: The Scapula Representation could be the Key: A Further Contribution to the ‘Klasies Pattern’ Debate

Past discussion on the unusual skeletal part representations at Klasies River Mouth is briefly summarized. Recent discussion in this journal, regarding the “Klasies Pattern”, has focused upon the differential destruction of small and large bovid bone epiphyses by carnivore ravaging and density-mediated attrition. Bartram & Marean (1999) argue, from ethnoarchaeological study and consideration of other archaeological sites, that, unless shaft fragments are painstakingly identified, the upper limb bone epiphyses of large bovids will be seriously under-represented. They therefore suggest that the “Klasies Pattern” is likely to be artefact of taphonomic and analytical processes. Klein, Cruz-Uribe & Milo (1999) replied with a defence of the analytical procedures employed during the original Klasies River Mouth analysis. They also state that there was very little evidence of carnivore ravaging at Klasies River Mouth. In this paper, it is pointed out that Bartram & Marean's (1999) study only considered the humerus, radius, femur, tibia and metapodia. However, in the “Klasies Pattern” it is the scapula that is most notably abundant in the small bovid classes and most notably scarce in the large bovid classes. It is argued that, from the study of bone mineral densities and Brain's (1981) carnivore ravaging experiment, there is no reason to expect a differentially greater taphonomic destruction of large bovid scapulae. In fact, exactly the reverse may be true. It is therefore argued that at least this aspect of the “Klasies Pattern” must be considered to represent human differential bone transport, rather than an artefact of taphonomic processes.     

Max Stirner, Hegel and the Young Hegelians: A reassessment

Max Stirner is generally considered a nihilist, anarchist, precursor to Nietzsche, existentialism and even post-structuralism. Few are the scholars who try to analyse his stands from within its Young Hegelian context without, however, taking all his references to Hegel and the Young Hegelians as expressions of his own alleged Hegelianism. This article argues in favour of a radically different reading of Stirner considering his magnum opus “Der Einzige und sein Eigentum” as in part a carefully constructed parody of Hegelianism deliberately exposing its outwornness as a system of thought. Stirner's alleged Hegelianism becomes intelligible when we consider it as a formal element in his criticism of Bauer's philosophy of self-consciousness. From within this framework it becomes quite clear what Stirner meant with such notions as “ownness” and “egoism”. They were part of his radical criticism of the implicit teleology of Hegelian dialectics as it found according to him its highmark in Bauer. In short, this article puts the literature on Stirner into question and tries for the first time in 30 years to dismantle Stirner's entire undertaking in “Der Einzige und sein Eigentum” by considering it first and foremost a radical criticism of Hegelianism and eventually the whole of philosophy while fully engaged in the debates of his time.     

“Random” hunting and the composition of faunal samples from archaeological excavations: A modern example from New Zealand

The ability of analyses of the age- and sex-composition of faunal samples from archaeological excavations to permit reliable inferences concerning prehistoric culling practices and, in particular, to distinguish between wild and domesticated animals is investigated by examining the demographic composition of 14 groups of red deer (Cervus elaphus) shot at random from a helicopter in the Southern Alps of New Zealand in early 1975. It is concluded that such “random” hunting can produce samples of bones that are apparently biased with respect to age and/or sex. The implications of these findings for prehistoric studies are discussed briefly with particular reference to the exploitation of red deer in Italy and Switzerland, and greater caution in excavating and analysing faunal samples is urged.     

Post-mortem DNA damage hotspots in Bison (Bison bison) provide evidence for both damage and mutational hotspots in human mitochondrial DNA

Post-mortem damage-driven mutations are a phenomena associated with ancient DNA (aDNA) studies. A previous study has demonstrated that the distribution of such mutations in human mitochondrial DNA is not random, but is concentrated in ‘hotspots’ that correlate with sites of elevated mutation rate in vivo. However, as the previous study was undertaken on human samples, it is possible for a critic to argue that the results might be biased through the presence of modern contaminant DNA sequences among the ancient DNA extracts. In this study we confirm the phenomena of DNA damage hotspots using a data set that is unlikely to be affected by contamination – cloned mitochondrial control region sequences extracted from 81 ancient bison (Bison bison). Furthermore, using published data from modern bovid specimens, we confirm that the damage hotspots correlate with sites of in vivo hypermutation. In conclusion, the aDNA sequences from archaeological specimens provide evidence that structural elements of mitochondrial DNA confer a degree of in vivo and post-mortem protection from sequence modification. This in turn provides useful insights into the debate as to whether mutational hotspots or mitochondrial recombination might best explain homoplasies observed on phylogenetic trees of human mitochondrial sequences.
