An in-depth discussion of a collaborative paper on "Historical Molecular and Microbiomic Interventions in the Gene-Culture Coevolution of Lactase Persistence" forms the body of this workshop. This work-in-progress undertakes a history of scientific inquiry into dairy consumption based on 1890s anthropological and cultural geography field studies on dairy pastoralism evolution, and demonstrates how research into lactose intolerance brought biomedical methods to bear upon that geographical research, while simultaneously hardening Eurocentric notions of racial difference. The first day is devoted to discussion of changes in assay techniques and objects of scientific research and how these illuminate a materials-based understanding of multi-disciplinary scientific field-formation, and the second day focuses upon future research and writing strategies.
