Indigenous DNA as a metaphor: Nation-building and scientific debates on the rediscovery of Taiwanese ancestry.

In this paper, I investigate the co-production of genetic research and national politics in post-martial law Taiwan. This entails analyzing two co-produced phenomena: the nationalization of biomedicine-in which the national discourse over racial/ethnic categories and ancestral origin increasingly shapes scientists' biomedical research; and the biomedicalization of the nation-in which people in public discourse increasingly use biomedical categories in characterizing national differences and identities. I analyze how the production and representation of scientific knowledge of the ancestral origins and genetic make-up of Taiwan have been embedded in Taiwanese politics. This includes the emergence of a new categorization into four great ethnic groups, multiculturalism, and the assertion of a distinct Taiwanese national identity, particularly in response to the People's Republic of China's claims of common ancestry. I also examine how the scientific findings produced in the lab have spilled out into both Taiwan and China through journals, media, history textbooks, and public disputes since the 1990s and brought about significant social impact.
