Bio 3184: Topics in American Literature: Ascendancy of Biology (spring) Same as L14 Elit 423.
Increasingly, over the past several decades post-Kantian divisions among areas of inquiry have been challenged, both by figures working within the sciences (Wilson's 'consilience,' Gould's scientific humanism, Zeki's 'inner vision') and in science studies (Stengers' 'cosmopolitics,' Latour's 'sociology of associations,' Haraway's 'situated knowledges'). The various approaches suggested here are just the tip of the iceberg. Whereas a century ago the physical sciences were clearly dominant, the early twenty-first century is marked by an ascendancy of the biological sciences. In this team-taught seminar, we will investigate relations between these two shifts in disciplinary formation as well as ways they have registered in scientific fictions and poetries by Merrill, Kenney and Powers, among others.

After a brief survey of pre-twentieth-century theories of heredity, this course examines the work of Gregor Mendel and its rediscovery in 1900, and its expansion as an interfield theory in combination with the chromosome theory, pioneered beginning in 1910 by T.H. Morgan at Columbia and R.A. Emerson at Cornell, and led to the expansion of classical genetics up to World War II. The beginnings of biochemical and molecular genetics in the1920s and 1930s developed rapidly after the war with the double-helix theory of DNA and the rise of molecular genetics. The course ends with examination of the Human Genome Project (Initiative) and the ramifications of genetic biotechnology. Throughout, emphasis is placed not only on the technical and theoretical developments comprising genetics as an epistemic field, but also on the economic, social, political and philosophical interconnections between genetics and society.
