Abstract

This essay examines the Mission paléontologique française of the 1920s, a series of scientific expeditions into the Ordos Desert in Inner Mongolia in which a team of Jesuit scholar-scientists worked with local collaborators to provide material for the Muséum d’Histoire Naturelle in Paris. The case study shows that the global and colonial expansion of Western science in the early twentieth century provided space for traditional scientific institutions, such as universalizing metropolitan collections and clerical scholarly networks, to extend their research projects. The linking of approaches, agendas, and geographic regions was facilitated by the concepts and practices of the deep-time sciences of geology, paleontology, and human prehistory. These were based on the interchange of expertise, common projects of unveiling the development of life, and the alignment of different regions and specimens. Moreover, the expeditions did not just conduct research based around global movement and transmission. They also conceptualized the ancient development of life in terms of movement, migration, and exchange. The act of forming research networks that linked Asia and Europe also led scientists to conceive of these regions as bound by deep natural processes. Circulation and transfer became important actors’ categories used to understand the origins and history of life.
