Phenetics,cladistics, and the search for the Alaskan ancestors of the Paleoindians: a reassessment of relationships among the Clovis,Nenana, and Denali archaeological complexes

Clovis, Nenana, and Denali are the earliest well-documented archaeological complexes in the New World. Clovis has been found at sites throughout the lower 48 states of the USA and in parts of Canada but not in Alaska, whereas Nenana and Denali have been found in Alaska but not elsewhere in North America. In 1991, Goebel and colleagues reported phenetic analyses of tool types from Clovis, Nenana, and Denali. They found that Nenana clustered more closely with Clovis than with Denali, and concluded from this that Nenana was likely ancestral to Clovis. Goebel et al.'s study has been cited frequently since it was published, and their conclusions have been widely accepted. Here we explain why analyses of the type performed by Goebel et al. are problematic and also demonstrate empirically that their results are dependent on the algorithm and distance measure used. We then reanalyze their dataset with a technique from biology called cladistics. Cladistics has replaced phenetics as the method of choice for reconstructing evolutionary relationships in biology, because it is more objective. The results of this analysis differ from those obtained by Goebel and colleagues. The results strongly suggest that Denali and Clovis are in fact more closely related to each other than either is to Nenana.     

Teaching the Craft of Archaeology: Theory, Practice, and the Field School

Field schools are a rite of passage for archaeologists, the first experience of what for many is the defining activity of the discipline: fieldwork. While teaching competence in practical techniques is the minimum goal of any field school, this technical training must be situated within the broader goals that drive the fieldwork. The University of Denver Archaeological Field School provides the fieldwork for the Colorado Coal Field War Archaeological Project. This project is an experiment in archaeology as political action in the present. It explores the possibility of an emancipatory archaeology through engagement with contemporary audiences and struggles. In this paper we discuss some of the ways we try to link technical training with the admittedly unusual theoretical and political goals of the project, teaching not only skills but an awareness of the responsibilities these skills should bring.     

An epidemic on wheels? Road safety,public health and injury politics in Africa (Respond to this article at http://www.therai.org.uk/at/debate)

Anthropologists have showed only marginal interest in road safety, despite the loss of some 1.3 million people killed in road crashes every year, the bulk of which occurs in ‘developing’ countries. 2011 marks the beginning of a UN Decade of Action for Road Safety. Its scope is ambitious: to save five million lives and fifty million injuries by the end of the ‘decade’ in 2020. In this article, the author examines the way public health professionals and educators have appropriated the language of epidemiology to argue that road death and injury can be viewed as an ‘epidemic on wheels’ or a ‘disease of development’, to mention two often cited epithets among participants in the global road safety lobby. One major consideration of interest to anthropologists and policy makers is to what extent this effectively essentializes road death in Africa and depoliticises its injury politics. Bearing in mind the historical context of medical interventions in Africa, the article examines the global road safety lobby and its affinity with public health as a form of transnational governance, arguing alternatively that if the UN Decade of Action on Road Safety is to have any significant impact, it must recognize more clearly the political stakes being raised in claims to reduce deaths and injuries caused by automobility.     

Modern observations: new ornithology and the science of ourselves, 1920–1940

The emergence and organisation of amateur networks of observation in Britain in the period between 1920 and 1940 are addressed in this paper. It examines the geographical, organisational and epistemological associations between networks of ornithological observation (traced through the British Trust for Ornithology), which emerged from the 1920s, and amateur ethnography (traced through Mass-Observation) which emerged in the late 1930s. I approach these ‘observational cultures’ as spaces which brought together new concepts of the local, of everyday nature and society, as well as the possibilities of changing the everyday. The paper suggests that popular observation during the period partly constituted a reframing of ways of knowing Britain differentiated through the everyday production of natural and social knowledge and the construction of the active citizen and new communities of practice.
