Integrating Science, Technology and Theory in Prehistoric Archaeology

It’s Wednesday, so another round of conference presentations we have filmed. This batch is from the TAG conference:

Session Abstract:

Prehistoric archaeology is at its best when scientific, technological and theoretical approaches can be integrated, creating dynamic approaches to myriad research questions, and providing a greater understanding of the archaeological past. It is increasingly important for the theorist to engage with scientific and technological approaches, and for the scientist to engage with theoretical approaches, not least to facilitate effective research collaborations.

The 21st century has seen the expansion of archaeological science, with the increasing use of aDNA, isotopic, proteomic, and ZooMS analyses providing new information on bone identification, diet, health and the movement of humans and animals. In tandem with this, the emergence of non-destructive and digital technologies, such as raman spectroscopy, pXRF, pXRD, 3D modelling and photogrammetry, has allowed for the analysis of diverse highly delicate and rare finds to be studied in unprecedented levels of detail and to be disseminated to a broader audience. New and refined techniques for dating, such as ultrafiltration and pre-treatment in radiocarbon, and advances in uranium series dating, have also allowed for increasing accuracy in the dating of material culture and sites. Alongside these scientific advances, the 21st century has also given rise to increasingly rich theoretical frameworks to explore cognition, the continued elaboration of non-western ontologies as an alternative to western assumptions, and a resurgence of interest in material culture, expressed through materiality as well as how things interact, such as new work on entanglement theory (Hodder 2012; 2016) and assemblage theory (Bennett 2010).

At present however, there still remains somewhat of a gap to be bridged between science and theory in prehistoric archaeology – a degree of epistemological division between ‘two cultures’ running in parallel (Snow 1959). As such, this session aims to create a forum for the discussion of how diverse scientific techniques and theoretical approaches can be combined to explore future research questions in prehistoric archaeology. To facilitate this aim, the session casts a wide net over the full span of the prehistory, with an interest in innovative blends of scientific and technological approaches and applications of theory, with emphasis on how science and theory can be integrated. We therefore invite speakers of all theoretical persuasions and technical or methodological specialisms from any prehistoric period or region. Contributions that focus on the nature of science and theory and how they might be integrated at a more abstract scale are also encouraged, as well as contributions that consider future directions for an integrated prehistoric archaeology.

Flint Provenancing: Combining Archaeometric and Archaeological Perspectives to Tackle Stony Issues

Determining the geological provenance of prehistoric flint artefacts is a subject that appears to prompt both interest and scepticism in equal parts. Recent innovation in scientific methodology has spurred a flurry of studies employing geochemical profiling techniques, such as portable EDXRF and (LA) ICP-MS, to link artefacts to their geological source areas (for example Pettit et al. 2012). These projects use geochemical data to infer characteristics of prehistoric subsistence behaviour aiming to enhance knowledge of raw material acquisition. However this popularisation of flint ‘sourcing’ has incurred criticism from the archaeometric community who suggest that, at times, science is being employed without a proper methodological background (see Shackley 1998).
This is particularly pertinent to studies using portable ED-XRF, as the precision and accuracy of data generated is negatively affected by the miniaturised nature of the device. Similarly from an archaeological perspective geochemical sourcing can be seen as an expensive extra that is not guaranteed to provide reliable results and cannot substitute for good geological knowledge and
macroscopic study. Further to this the process is inherently hampered by complexities within flint itself and the propensity for prehistoric populations to use highly chemically variable secondary flint deposits (e.g. glacial till). This presentation discusses combining archaeological and archaeometric perspectives in order to surmount these challenges, highlighting the need for
geochemical data to be considered from both a scientific and archaeological standpoint.

Prime movers: Considering the “driving forces” in the exploration of Creswell Crags through sound

This paper reflects critically on the authors gradual development of an approach used in the exploration of sound within archaeological landscapes. This has played out in both the Vale of Pickering, North Yorkshire (under the Sonic Horizons of the Mesolithic Project) and at Creswell Crags, Derbyshire/Nottinghamshire (under the SoundTracks Project), and has produced a series of novel research questions and outputs to date. Drawing on existing bodies of knowledge including archaeology, palaeoecology, geology, history, acoustic ecology, sound studies, acoustic engineering, compositional practice and experimental writing, this approach has begged, borrowed and stolen technological, theoretical and scientific approaches in pursuit of its core question: what did this place sound like?
In tracing this development, we articulate the varied and conflated influences on our approach, and argue that, within this context, a search for a “prime mover” or “origin point” for our work is somewhat moot. In doing so, we wish to ultimately question the character of truly interdisciplinary research, and the potential this offered for the generation and communication of different kinds
of knowledge and understanding.

The New Migrationists? Resolving studies of ancient DNA and archaeological theory

https://youtu.be/tLrHdxtiuiE Tom Booth, Natural History Museum

That we are living through a ‘Golden Age’ of Ancient DNA research is now a truism. Recent studies of European ancient human genomes have provided unprecedented insight into population movement and cultural change in prehistoric Europe. For instance, we can now say confidently that the spread of Neolithic things and practices across Europe was accompanied by a large-scale movement of people ultimately originating from the Near East. Palaeogenetic studies have identified several large-scale prehistoric movements of people into Europe that were usually accompanied by significant cultural change. Most of these studies have been conducted with little input from archaeologists and without much detailed discussion of the complexities of the archaeological evidence. In extreme terms, the results may be viewed alternatively as atheoretical objective inferences, unladen by ideological baggage or naive and reductive generalisations, reminiscent of the ‘bad old days’ of culture history. This talk will discuss recent studies of European ancient human DNA and how the tensions between archaeological and genetic perspectives may be resolved. Better communication and engagement between geneticists and archaeologists will ultimately produce richer and more incisive interpretations of the European prehistoric archaeological record. The power of Ancient DNA in refining our understanding of the past is undeniable, but archaeological evidence is essential for making sense of genetic data on anything other than a general scale. In addition the high volume of data produced by studies of ancient DNA, somewhat unintentionally, can be used to address specific questions about prehistoric social structures, which will always require robust interpretive frameworks.
