title: Darwin and the uses of extinction.
abstract: We currently view extinction with dismay and even horror, but Darwin saw extinction as ordinary and as necessary to evolutionary change. Still, the degree to which extinction is fundamental to his theory is rarely discussed. This essay examines Darwin's linking of the idea of "improvement" with that of natural selection and tracks a cluster of reasons for our changed valuation of extinction now. Those reasons demonstrate how scientific information and ideological preferences have reshaped the concept. The essay challenges the reader to assess some current assumptions about extinction and concludes by considering the shift in Darwin's own understanding from the "Origin" to the late "Autobiography".
