The Evolutionary Psychology FAQ
Last updated May 18, 2003.

This FAQ is written and maintained by Edward Hagen, formerly of the Center for Evolutionary Psychology, University of California, Santa Barbara, and now at the Institute for Theoretical Biology in Berlin. The FAQ assumes a basic knowledge of genes and natural selection. Its purpose is to outline the foundations of evolutionary psychology. These foundations are extremely robust (though not beyond criticism). The status of specific hypotheses (e.g., mate selection preferences, cheater detection modules) is more debatable, and will not be discussed in detail here. In addition, I address many of the common misconceptions about evolutionary psychology. This FAQ draws upon the work of many individuals. Comments and criticisms regarding it are welcome: e.hagen@biologie.hu-berlin.de
