Taking Students to the Museum: Interview with Warren D. Allmon, Judy Diamond, and Martin Weiss

Three museum professionals with extensive expertise in informal science education about evolution—Warren D. Allmon, Judy Diamond, and Martin Weiss—are interviewed about the interaction of teachers and natural history museums and science centers in improving the effectiveness of evolution education.     

Human Skeletal Populations Of The Northwestern Plains: A Preliminary Analysis

Abstract

Preliminary analysis has been completed on samples of American Indian skeletons from three museums in Wyoming, and special collections from Montana, Wyoming, northern Colorado and western Nebraska. All 84 specimens come from burial sites within the Northwestern Plains geographical region, and cover a temporal span of approximately 5,000 years. Fifty-four cranial and postcranial measurements, and 47 morphological observations were recorded for each complete specimen; and means and indices were compared among the various regional and temporal samples. Important temporal changes and a few regional differences are suggested by the preliminary results.     

Deconstructing the genesis of animal form

Santa Fe - with its museums and galleries full of art and crafts inspired by natural forms - was the perfect setting for a Keystone conference on vertebrate organogenesis in February 2004. Organized by Gail Martin and Cliff Tabin, the conference sessions were loosely subdivided into anatomical systems - 'skin, hair, teeth', 'pancreas, liver, gut', 'skeleton', and so on. However, from the outset, common themes emerged that transcended particular organ systems and generated a sense of unity and excitement among the participants.     

Cortical bone maintenance and geometry of the tibia in prehistoric children from Nubia's Batn el Hajar

The relationship between advancing age in adults and patterns of cortical bone maintenance has been extensively documented for archaeological populations (Dewey, et al., 1969; Van Gerven et al., 1969; Perzigian, 1973). Most recently, this research has been expanded to include a more thorough consideration of the geometric properties of bone in relationship to adult age changes (Martin and Atkinsin, 1977; Ruff and Hayes, 1983). To date, however, few studies have documented subadult patterns of cortical bone maintenance in archaeological populations and none have incorporated the relationship between patterns of cortical bone loss and gain and the changing geometric properties of growing bone. Using a sample of 172 tibias from children excavated from the Medieval Christian site of Kulubnarti, located in Nubia's Batn el Hajar, the present research examines the relationship between percent cortical area, bone mineral content, and cross-sectional moments of inertia. Among these children, bone mineral content increases steadily from birth in spite of a reduction in percent cortical area during early and late childhood. It appears, therefore, that tissue quality of the bone is not adversely affected by the reduction. Furthermore, the reduction in percent cortical area in later childhood corresponds to a dramatic increase in bending strength measured by cross-sectional moments of inertia. Thus, whether this cortical reduction is due entirely or in part to either normal modeling or nutritional stress, the tissue and organ quality of the bone is not adversely affected.     

Prehistory, Identity, and Archaeological Representation in Nordic Museums

In this article, I examine the variable representation of Saami (Lapp) prehistory in several Nordic museums. The analysis is situated at the intersection of (1) the examination of the ideology of archaeological practice, (2) the discourse about creation of indigenous identity, and (3) the visual culture of museum exhibitions. I describe and analyze displays about archaeology and prehistory from seven museums in Sweden, Finland, and Norway. The presentation of Saami prehistory differs significantly between majority community museums and those run by Saami communities. These presentations reflect ideologies implicated in building indigenous, nationalist, and pannational identities as well as in establishing legitimacy of Saami claims to land and heritage. Representations of the past are inevitably political because they are about linking people, place, and legitimacy. Ambiguities in these uses of prehistory are discussed, as is the globalizing role of the European Union.     

Dento-alveolar lesions and palaeodietary inferences from the Paso Alsina 1 site (eastern Pampean–Patagonian transition, Argentina)

Several archaeological researches in northeastern Patagonia and southeastern Pampas have evaluated various indicators of the diets of hunter-gatherers who inhabited these regions during the Late Holocene, including the role of plant foods. Dental analysis is an important way to introduce new information about subsistence. In this sense, the objective of this work is to document and interpret dento-alveolar lesions in an osteological sample recovered from the Paso Alsina 1 archaeological site (eastern Pampean–Patagonian transition, Argentina). This paper will explore the oral health status of individuals and discuss palaeodietary information of hunter-gatherers that inhabited the lower valley of the Colorado River during the final Late Holocene (ca. 500 years BP). The site is defined as a formal area bundle composed of 10 secondary multiple burials containing 56 individuals of both sexes and various ages (e.g., perinatal, infant, and adult). In this study, 781 teeth and 1036 alveoli from 47 maxillae and 38 mandibles were analysed from 51 adult individuals. The results indicate a moderate rate of dental wear, and dental calculus, and low percentages of caries, abscesses, and antemortem tooth loss. The information obtained suggests a diet based on a combination of proteins, fat and carbohydrates. Results are then compared with those from other lines of analysis for the study area and for the neighboring regions (northeastern Patagonia and southeastern Pampas).     

An Isolated Human Burial of Probable Woodland Association from Golden Gate Canyon,Colorado

Abstract

In late 1975 a human burial was discovered under rather fortuitous circumstances during quarrying operations for gravel in Golden Gate Canyon, just north of Golden, Colorado. The skeletal matenal, recognized as being prehistoric by authorities, was subsequently turned over to the University of Colorado at Denver for analysis. The burial is analyzed in terms of its metric, nonmetric and pathological features. The archaeological sequence in the immediate area of the discovery indicates a probable Woodland period age for the burial, although no cultural materials were recovered and all contextual relationships were destroyed prior to examination by archaeologists.     

Multi-millennial occupation in northwestern Laos: Preliminary results of excavations at the Ngeubhinh Mouxeu rock-shelter

With over half a century of political instability, resulting from armed conflicts, decolonisation and the Cold War, archaeological investigations in Laos have been rare, leaving little more than a blank page in the chapter of Southeast Asia's prehistory. Recent research has shown that Laos holds a rich prehistoric heritage. In conjunction with the research initiated by J. White who conducted the first professional archaeological survey of northern Laos since decades, we have extended the investigations to the Luang Namtha province. This work allowed us to gather important data about Hoabinhian stone tool assemblages and former cultures. In particular, the archaeological remains and dating from the Ngeubhinh Mouxeu rock-shelter indicate that this mountainous region of Laos has been inhabited over a long period of time that possibly spans as far back as 56,000 ± 3000 BP.     

Clients, Contracts, and Profits: Conflicts in Public Archaeology

The client-oriented approach to contract archaeology is a technical service rather than genuine scientific research. Such an approach fails to meet the requirements of the law, fails to satisfy the needs of archaeological science, and frequently fails to protect the client's interests. A client orientation encourages an excessive emphasis on profits from contract work. Profits not only exclude a balance of archaeological, client, and public interests but threaten the scientific future of contract work. Solutions to the problem of client-oriented work include better academic training as researchers, support for government archaeologists, a strong professional consensus on ethical and performance standards, and attention to public interests.

Integrating Modern Vegetation and Ethnographic Data to Understand Dietary Choices in the Past: the Case of the Southern Paiute,Utah

Ethnographic information on dietary plants can be cast into an ecological framework by using vegetation sampling techniques. Lists of ethnobotanical species become the basis of a dietary inventory that applies to a regional assemblage of vegetation types in a landscape associated with an archaeological site. But such lists are usually derived from many sources often without biogeographic or temporal reference. In effect, the dietary inventory represents potential food plants that may ultimately be found in archaeological deposits. The dietary palette, however, is composed of plant species that actually occur within the greater landscape of an archaeological site and that may or may not be known from the ethnographic record. Vegetation sampling provides a quantitative assessment of the dietary palette in the local ecosystem by using standard metrics, such as plant cover, basal area, density, and even productivity. By comparing vegetation data to the dietary inventory and archaeobotanical record, general patterns of foraging behavior as predicted by behavioral ecology are verified. This study of the Southern Paiute in south-central Utah also compares the plant species composition of modern and ancient landscapes, emphasizing a lack of correspondence between the dietary inventory and the dietary palette, as well as with the archaeobotanical record. Our example is from North Creek Shelter, a well-stratified archaeological site on the Colorado Plateau.     

Social Theory,Ecology and Epistemology: Theoretical Issues in Australian Prehistory

Analysis of certain discussions in Tasmanian prehistory reveals a tacit but strong environmental determinism. This approach, which centres on the notion of cultural adaptation, dominates current research in Australian prehistory. Recent theoretical discussions have, however, shown that the ecological approach is untenable; it is suggested that neo-marxist economic anthropology, emphasizing social rather than ecological relations, provides an alternative. The interpretation of archaeological data in social terms is a problem, but it should be dealt with rather than ignored. A further difficulty arises from the epistemological framework within which most archaeological work has operated: this is simplistic and empiricist. Greater consideration needs to be given to the role of theory in, and the social context of knowledge.     

Museums teach evolution

Natural history museums play a significant role in educating the general public about evolution. This article describes Explore Evolution, one of the largest evolution education projects funded by the National Science Foundation. A group of regional museums from the Midwestern United States worked with leading evolutionary scientists to create multiple permanent exhibit galleries and a curriculum book for youth. This program invites the public to experience current evolutionary research on organisms that range in size from HIV to whales. Learning research is being conducted on museum visitors to understand how they reason about evolution and to determine what influences the process of conceptual change.     

Subverting the Venue: A Critical Exhibition of Pre-Columbian Objects at Krannert Art Museum

My temporary exhibition in Krannert Art Museum, The Social Context of Violence in Ancient Peruvian Art (March 27–May 23, 2004), is transgressive and self-critical. While presenting a small number of objects in the university art museum's collection that depict ancient violence (battles, human sacrifice, and trophy head taking), the exhibition simultaneously argues that the objects themselves are the result of violence, specifically to the archaeological record through the act of looting. The exhibition further suggests that the looters are themselves the victims of a failed national economic system that does not enable them to earn a living wage as farmers and of an exploitative international art market that similarly pays them little for objects that become immensely valuable (financially and culturally) once out of the country. Museums, and especially university museums, may be enabling venues for the interrogation of their own hegemonic practices.     

Nature,Natives, and Nations: Glorification and Asymmetries in Museum Representation,Fiji and Hawaii

The Fiji Museum and Hawaii's Bishop Museum research and represent local indigenes differently, and more extensively, than they do the culture and history of descendants of plantation laborers. While these museums connect Japanese-Hawaiians and Indo-Fijians to themes of economic struggle and multiculturalism, the erstwhile 'natives'are strongly, if implicitly, connected to 'nature.'Against Foucaultian approaches depicting museums as 'modern' institutions of classification, this argument locates museums with a liberal focus on nature, natives and nations (three conceptions, from the same Latin root, for self-constituting objects) as descendants of imperial museum projects, and finds not classification but glorification originally organizing museum representations. The politics of museum representation concern dilemmas in glorification, not classification. The asymmetries traced here follow local will as well as institutional design.     

Modelling the Spread of Farming in the Bantu-Speaking Regions of Africa: An Archaeology-Based Phylogeography

We use archaeological data and spatial methods to reconstruct the dispersal of farming into areas of sub-Saharan Africa now occupied by Bantu language speakers, and introduce a new large-scale radiocarbon database and a new suite of spatial modelling techniques. We also introduce a method of estimating phylogeographic relationships from archaeologically-modelled dispersal maps, with results produced in a format that enables comparison with linguistic and genetic phylogenies. Several hypotheses are explored. The ‘deep split’ hypothesis suggests that an early-branching eastern Bantu stream spread around the northern boundary of the equatorial rainforest, but recent linguistic and genetic work tends not to support this. An alternative riverine/littoral hypothesis suggests that rivers and coastlines facilitated the migration of the first farmers/horticulturalists, with some extending this to include rivers through the rainforest as conduits to East Africa. More recently, research has shown that a grassland corridor opened through the rainforest at around 3000–2500 BP, and the possible effect of this on migrating populations is also explored. Our results indicate that rivers and coasts were important dispersal corridors, but do not resolve the debate about a ‘Deep Split’. Future work should focus on improving the size, quality and geographical coverage of the archaeological ¹⁴C database; on augmenting the information base to establish descent relationships between archaeological sites and regions based on shared material cultural traits; and on refining the associated physical geographical reconstructions of changing land cover.     

Predation on Colorado Potato Beetle Eggs by Generalist Predators in Research and Commercial Potato Plantings

Field studies quantified predation on Colorado potato beetle [Leptinotarsa decemlineata(Say)] eggs and determined the relationship between predation and egg mass abundance in research and commercial potato plantings in eastern North Carolina. Predator exclusion experiments were conducted weekly in research plantings. In addition, egg mass density and predation on egg masses were monitored throughout the season in research plots and commercial potato fields. Predation was an important source of mortality for Colorado potato beetle eggs. Survivorship of eggs exposed to predators was consistently, significantly lower than survivorship of eggs protected from predation. Averaged over 2 years, the mean survivorship of eggs protected from predation was 69%, compared with 26% survivorship of eggs exposed to predation. Regression analysis failed to detect any relationship between egg mortality due to predation and egg abundance. These results imply that efforts to reduce Colorado potato beetle populations selectively will not be offset by an according decline in abundance of natural enemies and therefore should be fully compatible with naturally occurring biological control.     

Technical note: Removal of metal ion inhibition encountered during DNA extraction and amplification of copper‐preserved archaeological bone using size exclusion chromatography

A novel technique for the removal of metal ions inhibiting DNA extraction and PCR of archaeological bone extracts is presented using size exclusion chromatography. Two case studies, involving copper inhibition, demonstrate the effective removal of metal ion inhibition. Light microscopy, SEM, elemental analysis, and genetic analysis were used to demonstrate the effective removal of metal ions from samples that previously exhibited molecular inhibition. This research identifies that copper can cause inhibition of DNA polymerase during DNA amplification. The use of size exclusion chromatography as an additional purification step before DNA amplification from degraded bone samples successfully removes metal ions and other inhibitors, for the analysis of archaeological bone. The biochemistry of inhibition is explored through chemical and enzymatic extraction methodology on archaeological material. We demonstrate a simple purification technique that provides a high yield of purified DNA (>95%) that can be used to address most types of inhibition commonly associated with the analysis of degraded archaeological and forensic samples. We present a new opportunity for the molecular analysis of archaeological samples preserved in the presence of metal ions, such as copper, which have previously yielded no DNA results.

Economic Analysis of the Legal Regimes Governing Salvage of Historic Shipwrecks

This article offers an economic analysis of the international and U.S. laws governing the recovery of archaeological data from historic shipwrecks. The framework combines values of treasure salvage and archaeological knowledge. It is suggested that U.S. salvage law, sometimes extended to international waters, gives insufficient protection to archaeological value, but that UNESCO's Convention on the Protection of the Underwater Cultural Heritage goes too far in the other direction. Two other legal regimes (government-salvager and interstate agreements) are shown to have the potential to maximize the social values of historic shipwrecks. It is also suggested that a move towards maximizing social values would be promoted if the U.S. admiralty courts tied the size of salvage awards more closely to the quality of the archaeological work performed.     

The domestication of Helianthus annuus L. (sunflower)

All modern domesticated sunflowers can be traced to a single center of domestication in the interior mid-latitudes of eastern North America. The sunflower achenes and kernels recovered from six eastern North American sites predating 3000 b.p. that document the early history of this important crop plant are reanalyzed, and two major difficulties in the interpretation of archaeological sunflower specimens are addressed. First, achenes and kernels obtained from a modern wild sunflower population included in a prior genetic study because of its minimal likelihood for crop-wild gene flow, and its close genetic relationship to domesticated sunflowers, provide a new and more tightly drawn basis of comparison for distinguishing between wild and domesticated achene and kernel specimens recovered from archaeological contexts. Second, achenes and kernels from this modern wild baseline population were carbonized, allowing a direct comparison between carbonized archaeological specimens and a carbonized modern wild reference class, thereby avoiding the need for the various problematic shrinkage correction conversion formulas that have been employed over the past half century. The need for further research on museum collections is underscored, and new research directions are identified.     

TMJ osteoarthritis: a new approach to diagnosis

Disorders of the temporomandibular joint (TMJ), including TMJ osteoarthritis (TMJ OA), are the topic of intensive clinical research; however, this is not the case in the archaeological literature, with the majority of work on the subject ceasing with the early 1990s. The methods employed in the diagnosis of TMJ OA within the archaeological work appear nonrepresentative of the disease and may have led to erroneous assumptions about the pattern and prevalence of OA. This current work presents a new method for evaluating OA specifically for the TMJ, considering both the biomechanics of the joint and the mechanisms of the disease. Totally, 496 specimens (including a group of modern documented specimens) were analyzed for the presence of TMJ OA using the following criteria: eburnation, osteophytes (marginal and new bone on joint surface), porosity, and alteration to joint contour. The results suggest that eburnation occurs rarely in the TMJ, so should not be used as an exclusive criterion. Rather a combination of at least two of the other criteria should be used, with osteophytes and porosity occurring the most frequently on both the mandibular condyle and articular eminence. Additionally, the prevalence of TMJ OA in the modern assemblage was similar to that observed in current clinical research, suggesting that the method employed here was able to produce a reasonable approximation of what is found in contemporary living populations.
