Show moreThe research contained in this dissertation explores the origins of fire making in prehistory, focusing primarily on the fire use practices and fire production capacities of Neandertals. The dissertation is comprised of four peer-reviewed articles published in the journals Quaternary International, PLoS ONE, Journal of Archaeological Science and Scientific Reports, respectively, which are flanked by an introductory and synthesis chapter. The early chapters confront the debate surrounding the prevalence of fire use by Neandertals and discuss avenues by which we, as archaeologists, can better understand how fire use manifests in the Palaeolithic archaeological record. The latter chapters seek to provide a means for identifying artefactual evidence for fire making by Neandertals, ultimately presenting a series of French Middle Palaeolithic tools that exhibit use traces suggesting they were employed as fire starters, making these the earliest evidence for the regular production of fire by humans currently known.

Show moreEvidence for fire use becomes increasingly sparse the further back in time one looks. This is especially true for Palaeolithic assemblages. Primary evidence of fire use in the form of hearth features tends to give way to clusters or sparse scatters of more durable heated stone fragments. In the absence of intact fireplaces, these thermally altered lithic remains have been used as a proxy for discerning relative degrees of fire use between archaeological layers and deposits. While previous experimental studies have demonstrated the physical effects of heat on stony artefacts, the mechanisms influencing the proportion of fire proxy evidence within archaeological layers remain understudied. This fundamental study is the first to apply a computer-based model (fiReproxies) in an attempt to simulate and quantify the complex interplay of factors that ultimately determine when and in what proportions lithic artefacts are heated by (anthropogenic) fires. As an illustrative example, we apply our model to two hypothetical archaeological layers that reflect glacial and interglacial conditions during the late Middle Palaeolithic within a generic simulated cave site to demonstrate how different environmental, behavioural and depositional factors like site surface area, sedimentation rate, occupation frequency, and fire size and intensity can, independently or together, significantly influence the visibility of archaeological fire signals.
