   Recent work in the philosophy of biology (Orzack and Sober 1994a, Sober 1996, Amundson 1988, 1990, Godfrey-Smith 2001) has helped uncover three “flavors” of adaptationism; these reflect differences in beliefs among current professional developers and users of evolutionary arguments. They represent commitments about the state of nature, about the way to do science, and about what is important to study.
