The Technological Condition of Human Evolution: Lithic Studies as Basic Science.

The recent elaboration and rapid expansion of aDNA, paleoproteomics, and related fields have propelled a profound "biomolecular turn" in archaeology and fundamentally changed the topology of archaeological knowledge production. Such a transformation of the archaeological research landscape is not without consequence for long-standing research practices in the field, such as lithic analysis. This special issue derives from the session Old Stones, New Eyes? organized by the authors at the UISPP World Congress in Paris in 2018, which aimed to explore the future of lithic studies. An underlying theme of our session was the felt need to respond to the increasing marginalization of lithic research in terms of its capacity to (1) contribute to the grand narratives of early human evolution and (2) better articulate the role and significance of lithic studies in interdisciplinary human origins research. In this editorial, we briefly outline some of the questions and challenges raised by the biomolecular turn and advocate for a more self-conscious and reflexive stance among lithic experts. We argue that lithic studies fulfill all necessary requirements to act as a basic science for human origins research and that its role and status depends less on technological advances, such as, e.g., improved computing facilities, novel analytical software, or automated shape capture technologies, than on continuous work on the conceptual and methodological foundations of inquiry. We finally draw attention to the unique capability of lithic studies to shed light on the human technological condition and illustrate this potential by introducing and briefly discussing the papers included in this issue.
