Spondylolysis in Inuit skeletons from Arctic Canada

Inuit skeletons from archaeological sites in Arctic Canada were examined for the presence of spondylolysis. The largest series represent the Thule culture and historic Inuit from northwest Hudson Bay and Labrador, and Sadlermiut from Southampton Island. The condition was found in 90 individuals, with a total of 120 affected vertebrae producing 198 hemi‐arch defect sites. As in other studies, L5 is affected most frequently, followed by L4 and L3, but examples of L1, L2, L6, and S1 involvement are represented. Incomplete separations account for 20% (40) of the 198 defects, and 5% (10) occur at sites other than interarticularis. Affected males outnumber females at a ratio of 2.4 to 1. The condition was found to increase in frequency from adolescence to young adulthood, and then decrease to middle adulthood and decrease again to old adulthood, but the drop in frequency with age in the adult categories is significant only at the .20 level. Where comparisons could be made, the data obtained from the Canadian Inuit closely resemble those obtained from Alaskan Eskimos and Aleuts, especially their closest linguistic relatives, Inupiat speakers in northern Alaska.

Minimally destructive DNA extraction from archaeological artefacts made from whale baleen

Here we demonstrate the successful extraction and amplification of target species DNA from artefacts made of whale baleen collected from excavations of past palaeo-Eskimo and Inuit cultures in Greenland. DNA was successfully extracted and amplified from a single baleen bristle of 1.5 cm length dated based on archaeological context to the period of the Saqqaq culture, more than 4000 years ago and following decades of storage at room temperature at the National Museum. The results reveal ancient baleen in archaeological material as a potential source of DNA that can be used for population genetic studies. We conclude that genetic investigation of historical baleen collections can contribute to our knowledge of the prehistoric population genetics of baleen whales, for example by quantifying the impact of modern whaling on the genetic diversity of bowhead whales.     

Greenland in the center: what happened when the Danish–Norwegian officials met English and Dutch whalers in Disko Bay, 1780–1820

Between 1780 and 1820 crucial changes took place in the economic and cultural relationship between Denmark–Norway and its North Atlantic dependencies. In Greenland, the state imposed a stringent set of social and economic controls, at the same time when the restrictions on trade in Iceland and Northern Norway were relaxed. In 1776 the Royal Greenlandic Trading Company was established, but during the eighteenth century the waters around Greenland were a hub of international whaling trade as Dutch, American, and British ships came into contact with the Inuit, who were legally under Danish-Norwegian social regulation. This article uses records of Danish officials in Greenland and those of incidental observers to understand the disjuncture between the law of Denmark–Norway and the realities of Disko Bay. The officials contended with better equipped foreign ships, the Inuit desire to trade with these ships, and communication problems with the capital. This period is characterized by experimentation with different methods of production, contrasting strongly with the later nineteenth century, in which Danish–Greenlandic policy became more restrictive. By the nineteenth century international whaling trade had followed the declining whale stocks westward to the Canadian and American waters, so Denmark-Norway could impose these restrictions more easily.     

Cultural Identity and the Archaeological Construction of Historical Narratives: An Example from Chaco Canyon

The Bonito Phase (ca. AD 850 to 1140) in Chaco Canyon, New Mexico, is widely assumed by archeologists to reflect the growth and decline of a coherent sociopolitical entity, one of the classic examples of emergent social complexity among ancient indigenous North American populations ending in a societal collapse. This understanding of Chaco is based, in part, on the interpretation of temporal changes in material culture as intentional efforts to maintain cultural identity and continuity in the face of social disruption. In this study, I suggest that the Bonito Phase actually encompassed at least one major episode of cultural discontinuity, calling into question the perception of a distinct “Chaco society.” Instead, patterns of material production in Chaco point to multiple cultural identities linked to serial reoccupation of the canyon.     

Decadal-scale sea ice changes in the Canadian Arctic and their impacts on humans during the past 4,000 years

Abstract

Climate warming of >1.5°C over three decades has diminished Arctic sea ice and forced drastic changes on Inuit people of the Canadian Arctic. Discontinuities in archaeological records also suggest that climatic changes may have caused site abandonment and life style shifts in Paleo- and Neo-eskimo societies. We therefore examine the decadal-scale palaeoclimatic changes recorded by quantitative palynological data in marine records from Coburg Polynya, near Palaeo- and Neo-eskimo settlements on the North Devon Lowlands, and from the North Water Polynya between Canada and Northwest Greenland. Palaeotransfer functions from dinoflagellate cyst assemblages provide quantitative estimates of changes in sea surface temperature (SST) and sea ice cover (SIC) with the accuracy of historical measurements.

Both sites record temperature variations of 2–4°C corresponding to changes in hunting modes and occupation-abandonment cycles on Devon and Ellesmere Islands. Our data show that from ～6500 to 2600 BP, there were large oscillations in summer SST from 2–4°C cooler than present to 6°C warmer and SIC ranged from 2 months more sea ice to 4 months more open water. The warmer interval corresponds to the period of pre-Dorset cultures that hunted muskox and caribou. Subsequent marine-based Dorset and Neo-eskimo cultures correspond to progressively cooler intervals with expanded sea ice cover. The warming took ～50–100 years and lasted ～300 years before replacement by colder intervals lasting ～200–500 years. These climate oscillations are more rapid than the archaeological cultural changes, but are of similar length to successive Palaeoeskimo occupations in the Nares Strait region.     

The Place of the Dog: AKC Breeds in American Culture

The American Kennel Club (AKC), the primary registry agency for purebred dogs in the United States, had recognized 138 breeds through September 1995. An investigation of the source areas of these breeds reveals the cultural authority of Great Britain in organized dog breeding in the United States. Although Great Britain accounts for more than one-third of the AKC breeds, however, its importance has declined. Dogs from Asia account for more than one-fifth of the breeds recognized since World War II. Breed names that contain toponymic elements (such as Sussex Spaniel) usually reinforce the importance of the area in which the breeds were developed. An analysis of the patterns of geographic names reveals a pronounced emphasis on Western Europe, particularly Great Britain. A decline in the prominence of names from Europe has occurred. Asian name sources have become more important, and Australia and Africa have begun receiving attention. North America as a source of breeds as well as a source of naming has occupied a relatively minor role throughout the AKC's history. American breeders and promoters of purebred dogs have tended to look outward, especially toward Europe, for sociocultural forms.     

Fossil dogs and wolves from Palaeolithic sites in Belgium,the Ukraine and Russia: osteometry,ancient DNA and stable isotopes

Using multivariate techniques, several skulls of fossil large canids from sites in Belgium, Ukraine and Russia were examined to look for possible evidence of the presence of Palaeolithic dogs. Reference groups constituted of prehistoric dogs, and recent wolves and dogs. The fossil large canid from Goyet (Belgium), dated at c. 31,700 BP is clearly different from the recent wolves, resembling most closely the prehistoric dogs. Thus it is identified as a Palaeolithic dog, suggesting that dog domestication had already started during the Aurignacian. The Epigravettian Mezin 5490 (Ukraine) and Mezhirich (Ukraine) skulls are also identified as being Palaeolithic dogs. Selected Belgian specimens were analyzed for mtDNA and stable isotopes. All fossil samples yielded unique DNA sequences, indicating that the ancient Belgian large canids carried a substantial amount of genetic diversity. Furthermore, there is little evidence for phylogeographic structure in the Pleistocene large canids, as they do not form a homogenous genetic group. Although considerable variation occurs in the fossil canid isotope signatures between sites, the Belgian fossil large canids preyed in general on horse and large bovids.     

DNA analysis of archaeological sheep remains from China

Recent research has thrown considerable light on the history of the domestic sheep, but has not extended to ancient sheep specimens. In the present study, ancient DNA analysis was carried out on eight archaeological sheep remains recovered from Erlitou archaeological site in Henan Province (ca. 2100–1800 B.C.) to explore the genetic structure of ancient sheep and the phylogenetic relationship between ancient and modern sheep. We analyzed the control region sequences and coding regions of mitochondrial DNA from the remains by direct sequencing and restriction fragment length polymorphism analysis, respectively. Our results reveal that all ancient sheep belong to lineage A defined by modern sheep sequences. Phylogenetic analysis shows that neither argali (Ovis ammon) nor urial (Ovis vignei) mtDNA is closely related to Erlitou ancient sheep. In addition, our results suggest that ancient DNA analysis can serve as a powerful tool in tracing prehistoric population movement.     

Genetic analysis of archaeological wood remains: first results and prospects

A total of 51 ancient oak wood samples originating from various European archaeological sites, dating from the Neolithic period to the 18th century, were assayed for the presence of reproducible chloroplast (cp) DNA sequences. Five polymorphic chloroplast fragments were targeted. Only five of the samples could be fully genetically characterised, revealing four different oak cpDNA haplotypes. In all cases, the haplotypes detected on ancient woods and the haplotypes characterised from fresh samples from the same localities matched. Overall, this congruence is consistent with a genetic continuity between ancient and modern European oaks, confirming the hypothesis that the mapped genetic patterns largely reflect the original structure that established during the post-glacial. This stability of the genetic structure implies that, in the future, the technique could be used to infer or confirm the transport of wood by man, providing interesting perspectives for the genetic analysis of ancient woods.     

The other cold war: the United States and Greenland’s ice sheet environment, 1948–1966

During the early Cold War, no part of the Arctic was as important to the United States’ strategic interests as Greenland: situated on the shortest straight-line route between the industrial centers of the two superpowers, Greenland was integral to North American continental security. The US desire to control Greenland, however, was complicated by the island’s isolated geography, harsh climate and barren landscape. Between 1948 and 1966, US forces in Greenland were entrenched in the ‘other cold war’: the struggle with the ice sheet environment which threatened to impede American capabilities in the region. This paper explores the ‘other cold war’ through two case studies: US scientific efforts to understand and cope with polar whiteouts and the plastic deformation of ice. These case studies illuminate a struggle between two philosophical approaches to nature: a brash, aggressive approach which aimed to conquer the Greenland environment, and a more nuanced approach which aimed to collaborate with that environment. I show that the second approach won out as Greenland’s exceptional geography and environment forced the US military to reassess its relationship with nature: rather than striving for control over the island space, US military personnel ultimately chose strategic cooperation with that space.     

Frequency of Complete Cleft Sacra in a Native American Sample

The purpose of this paper is to contribute to the current understanding of the variability of complete sacral clefts in human populations by presenting new data on a large prehistoric and historic Native American skeletal sample (n = 1943). Results are examined by age, sex, time period, and regional distribution and compared with reported frequencies of complete sacral clefts in other modern, historic, and ancient populations. In all, 1.6% of the sample exhibited complete sacral clefts, including 2.1% of males and 1.1% of females. Although males exhibit a frequency twice as high as females, this difference is not statistically significant. However, within the Alaskan sample, the sex difference was significant (p = 0.002), with 3.4% of males and 0.5% of females exhibiting complete clefts; these differences may be related to mechanical influences during growth and development in males. Differences among age groups are not significant. Regional comparisons among Alaska, Eastern Woodlands, Great Basin/Northwest/California, Great Plains, and Southwest showed no significant differences overall, but Alaska (2.2%) and Great Plains (0.5%) do show a significant difference (p = 0.024). No significant differences were found between prehistoric, protohistoric, and historic/recent samples, suggesting a lack of a secular trend in frequency of complete sacral clefts in Native American populations. One individual exhibited an enlarged canal, which may be indicative of a more severe condition. Copyright © 2012 John Wiley & Sons, Ltd.     

Technical aspects of a worked proboscidean tusk from Inmachuk River,Seward Peninsula,Alaska

Prehistoric reduction sequences of proboscidean ivory have been described and discussed within the Russian and European Upper Paleolithic archaeological literature. A culturally modified proboscidean tusk (Mammuthus sp.) in Seward Peninsula, northwestern Alaska, displays longitudinal grooving, providing an insight into a reduction technique rarely described within North American archaeological literature. Similar reduction sequences have been described for the production of bone, antler and walrus ivory artifacts in the North American prehistoric record; however, examples on proboscidean ivory are extremely rare.     

Using finite element methods to analyze ancient architecture: an example from the North American Arctic

Developing theories of vernacular architecture in archaeology has been hindered by the lack of a defined methodology for studying ancient buildings, and the absence of information on the mechanical properties of construction materials uncommon in today's building practices. In this paper we use Finite Element Methods and recent research on the structural properties of whalebone to analyze the architecture of Thule semi-subterranean houses. These unique dwellings were constructed and used by the ancestors of Inuit/Eskimo peoples in the Canadian Arctic and Greenland. Little is known about how they were designed and constructed because few have ever been discovered intact. The substantial weight of whalebone roof frames suggests that some designs would have performed better than others. Poorly planned houses, or the use of whalebone in a symbolic rather than strictly utilitarian capacity, may have resulted in higher maintenance costs, thereby shortening their anticipated use life. In extreme cases, errors in design, or the failure of materials may have caused dwellings to collapse, resulting in injuries or possibly even death. We demonstrate through this case study that Finite Element Methods constitutes an effective methodology for studying ancient buildings, with the proviso that more research is needed on the mechanical properties of building materials used in the past.     

A double dog burial from San Nicolas Island, California, USA: osteology, context, and significance

Recent archaeological excavations on San Nicolas Island, located off the coast of southern California, revealed the remains of a double dog burial interred sometime during the 13th and 14th centuries. Two carefully laid to rest and possibly sacrificed juvenile, female domestic dogs (Canis familiaris) between the ages of 1 and 6 months were found within a Native American village. Digestive tract residues include burned and unburned fish and marine mammal bone that suggest scavenging behavior or direct feeding by humans. Breed classifications place it between the Short-Nosed Indian dog and the Plains-Indian dog, likely representing a cross between those and other varieties of North American dogs. Comparisons with other dog burials from archaeological sites across southern California suggest commonalities and possible cultural linkages.     

Trauma and pathology of a buried dog from San Nicolas Island,California, U.S.A.

To date more intact dog remains have been found on San Nicolas than on any of the other seven California Channel Islands. However, little is known about them. During the 2007 summer field season we excavated a medium sized young male dog in a flexed burial position from a pit at CA-SNI-25, a large Native American village site. The dog exhibits hypodontia, noticeable tooth attrition, severe scapular trauma, and vertebral, rib, and phalanx pathologies. Most of the injuries appear to have resulted from a severe blunt force trauma of unknown origin and it is likely the dog would not have survived without human care. The results of our analysis contribute to the, somewhat limited, published data on archaeological dogs in California. In this paper we describe the biological characteristics of the dog especially his anomalies and pathologies and compare them with published reports of other North American archaeological dogs with similar conditions.     

Toward an archaeology of late prehistoric Eskimo bands in coastal northwest Alaska

The methodology of analogical explanation of prehistoric Eskimo remains in northwest Alaska is examined. The sociospatial organization of Wales or, Kingigan, settlement and the greater Kingikmiut territory is evaluated as an example based on ethnohistorical studies and archaeological excavations carried out at three sites in the locality since 1926, and relationships between the archaeological material and historic socio-spatial divisions of Kingigan are explored. The review reveals that only two historic family compound locations have been sampled archaeologically, and that several others have not yet been sampled. However, existing samples nevertheless represent the larger Agianamiut, Kiatanamiut and Kurigitavik districts in the settlement, ca. AD 1800–1850 and extending back to prehistoric times from ca. AD 1000. A nomenclature for socio-spatial units is proposed that includes compound families, local bands, tribal capitals and tribes based on examples of historic Eskimo territorial organization. Caution is suggested in applying the nomenclature to prehistoric cultures in cases where continuity of artifact forms, art styles and motifs with historic local cultures are not demonstrable. Application of historic Eskimo analogues to prehistoric entities such as Birnirk and Punuk cultural remains risk fallacious interpretations because continuity with historic examples are not demonstrable and alternative explanations cannot be eliminated.     

Oil in the Arctic 1. Historical,Environmental and Regional Perspectives

Abstract

An ecologist's point of view of the historical, scientific and social background to the Alaskan pipeline and offshore oil is presented ranging over many discipline and their close interplay. Starting with a deep concern about the protection of the Arctic's unique environment and the oil industry's impact upon it, the work of the Alaska Conservation Society is reviewed. The lack of biological information about Alaska's hinterland made environmental surveillance of the pipeline difficult. The political conflict between State and Federal authorities has hindered scientific effort and the author concludes that the outlook of this many-faceted interdisciplinary impact of technology on the Arctic and Alaska is at present uncertain.     

Nuutauniq (Moves in Inuit Life): Arctic Transformations and the Politics of Urban Inuit Mobility

ABSTRACT

Today, one in four Inuit live outside of Inuit Nunangat, the Arctic territory incorporating the four northern Inuit land claims regions. With the majority of those Inuit living in cities, the issue of urban Inuit populations is becoming a more prominent focus for policy debate. In this article, I argue that urban Inuit mobility is a historically complex and multilayered phenomenon embedded in, not detached from, the major processes of social transformation affecting Inuit across the Canadian Arctic from the mid-twentieth century on. I use this analysis to explore the diverse formulation of Inuit-specific policy initiatives in Montreal, a task that, I show, is made easier by the Montreal Inuit radio show called Nipivut.
