Darwin’s theory of evolution by natural selection is central to one of the most profound revolutions in the history of thought, generating stunning insights but also some misunderstanding and tragic abuse. This seminar aims to provide a clear understanding of how natural selection works, and how it doesn’t. We will examine objections to the theory; how the environmental and health problems we face today reflect processes of natural selection; and recent attempts to understand why we get sick, how we respond to disease, why we get old, why we choose mates the way we do, and more. Class sessions will feature a mix of lecture and discussion of concepts and issues. Students will also engage in small group projects—cooperative explorations of problems raised in class or in the readings and/or designing mini research projects.
