• Evolution and Optimality: Feathers, Bowling Balls, and the Thesis of Adaptationism

      Sober, Elliott; University of Wisconsin, Madison (1996-01-01)
      This paper discusses the thesis of adaptationism in evolutionary biology. It is argued that there is a serious scientific question here whose answer is not yet in hand. The truth or falsity of adaptationism is a substantive question about the history of life that must be decided on a trait by trait basis.
