The University of Lucerne Research Groups ‘History Within: The Phylogenetic Memory of Bones, Organisms, and Molecules’ and ‘Collecting Humanity: How Human Remains are Made into Museum Objects’ and the Max Planck Research Group ’Historicizing Knowledge about Human Diversity in the Twentieth Century’ (Berlin) are jointly organising a conference ’Visibility Matters: Rendering Human Origins and Diversity in Space and Time’. The conference aims at bringing together scholars from various disciplines who work on the visualization of human origins and diversity. A particular focus will be on the diagrammatic forms of representation. Strategies of diagrammatic representation typically employ a series of textual, symbolic, and pictorial elements. Such strategies may include, among others, specific ways of subjectification; the serialization, spatialization, and temporalization of data; the storage of standardized data sets; and staging techniques of protagonists, events, and processes, notably in the architecture of exhibitions, parks and museums, and through the medium of film and animation.
