Since its inception in the history of ideas, the concept of race has been oscillating between the political-social and biological domains. While the political-social perspectives have been dominant in the second half of the 20thcentury, “race” seems to be subject to a new kind of biologisation during the time of epigenetics. In this article, I show that the epigenetic approach to race echoes earlier externalist conceptions of race, and that it leads to the articulation of naturalism, environmentalism, and biosocial constructivism. (...) I argue that it invites us to think about race as a relational, plastic, and accidental property, and so-called “racial groups” as biosocial historically contingent constructs. (shrink)
