The role of experimental knapping in empirically testing key themes in the evolution of lithic technology: reduction intensity, efficiency and behavioural complexity Antoine Muller BA (archaeology) BA Honours (archaeology) A thesis submitted for the degree of Master of Philosophy at The University of Queensland in 2017 School of Social Science Abstract Experimental knapping has complimented and stimulated lithic analyses for over a century. Throughout this period, the discipline has witnessed an increase in the scientific rigour and theoretical grounding with which these studies are conducted. This thesis charts these key trends and in doing so establishes a best-practice model of experimental knapping, the veracity of which is in turn tested using four new lithic experiments. These case-studies employ experimental knapping to advance our understanding of flake platform measurement, reduction intensity, technological efficiency, and behavioural complexity. The first case-study, Chapter 3, offers a more accurate and precise calliper-based method of flake platform measurement that relies on simple geometric approximations of platform shape rather than the inflexible and unreliable existing method of multiplying platform width by thickness. In Chapter 4, a new reduction intensity metric for backed blades, a hitherto overlooked tool-type, is developed and tested on the backed blades from an early Neolithic site in Turkey. This new metric allows a reconstruction of the raw material consumption patterns at the site, finding that the backed blades likely contributed to conserving the inhabitants’ scarce lithic raw material. Meanwhile, Chapter 5 outlines the results of a comparison of the raw material efficiency of eight different lithic technologies, finding that lithic technological efficiency was a generally ascending trend over the last 3.3 million years and that the main transition in efficiency occurred between the Lower to Middle Palaeolithic. On a similar time-scale, Chapter 6 explores the behavioural complexity of five different technologies by charting the relative levels of hierarchical organisation required for their production, finding equivalencies in the behavioural complexity required for the tool-kits of Neanderthals and their contemporary Homo sapiens. These four case-studies, coupled with a consideration of existing knapping experiments, allow an understanding of how experimental knapping is embedded in the broader archaeological research process, and ultimately tests the efficacy of a best-practice model of experimental knapping. This model identifies the initial scope, methodological control, and breadth of interpretations as the key variables dictating the validity of an experiment. While knapping experiments may differ markedly in their scope and control, they do not necessarily vary in their validity. Instead, it is the interplay of these variables that dictates the validity of experimentation. Within this best-practice model, lithic experiments are most robust when the scale of the initial scope, methodological control and ensuing interpretations are congruent, and when they involve explicit and falsifiable hypothesis testing. ii Declaration by Author This thesis is composed of my original work, and contains no material previously published or written by another person except where due reference has been made in the text.

Chapter 5 built on that pilot study by expanding the sample and analyses conducted. Dr Tyler Faith provided assistance with statistical analyses and insightful comments on the manuscripts presented here. Tierney Lu, Kasih Norman, Perri Braithwaite, Kathy Lai, and Jackie Child, participated in the inter- observer variability portion of Chapter 3. Statement of Parts of the Thesis Submitted to Qualify for the Award of another Degree Chapter 6 was based on a pilot study conducted by the author (AM), submitted as partial fulfilment of the requirements of an Honours degree at the University of Queensland, 2014. This chapter significantly expanded the sample, methodology, theory, and analytical scope of the pilot study. vi Acknowledgements I would like to sincerely thank my supervisors, Chris Clarkson and Andrew Fairbairn for their unending guidance, feedback and support throughout this process. A special thank you goes to Chris Clarkson for imparting and contributing his abundant expertise in lithic technology and knapping, on which this thesis so often relied.
