In this sophisticated and insightful anthropological critique of the global surge in bioscience and bioeconomic activity, we are reminded that global biodata extraction and organization have become a centering force of life sciences everywhere. Peter C. Little, Rhode Island College This book poses a critical question needed at this moment. Is it possible to build ethical infrastructures for learning and thinking about our biologies and health? Using an impressive ethnographic practice, the authors deliver a powerful call for the social groundedness of our knowledge not only for biodata, but beyond. Deboleena Roy, Emory College of Arts and Sciences This book deftly shows how to understand todays big biodata investments. Gonzalez-Polledo and Posocco evocatively demonstrate how sedimented histories of biocolonial extraction carry forward in data repositories, and how bioinformation dataflows cross domains of knowledge and practice, accruing value and redefining life in the process.
