ABSTRACT: This article discusses rape from a biological perspective and dispels some
myths about what that perspective is, and what it entails. It emphasizes that evolution
applies to rape, just as it does to any feature of life. How exactly evolution applies is
unclear, but various hypotheses are presented and evaluated. A rape-specific adaptation
in men seems likely, but more research is needed to discriminate the rape adaptation
hypothesis from the incidental effect hypothesis. In addition, this essay suggests that the
widespread opposition to studying rape from an evolutionary biological perspective stems
from a bias against viewing rape in biological terms, a bias we must understand and
confront if rape research is to progress.

(1999).
Many people dislike the idea that rape has a biological basis, and have
extreme difficulty thinking or talking about rape in biological terms.1 The
widespread opposition to the study of rape from an evolutionary biological
perspective stems, in part, from misunderstanding biological facts and theory and
the inferences that can be drawn from supporting data.
I. COMMON MISUNDERSTANDINGS
Most people have little knowledge of developmental biology. As a result,
they do not understand that developmental programs of organisms are evolved

Mar.-Apr. 1994, at 60-63 (supporting this inference and concluding that rape literature is rarely
scientific and frequently explicitly anti-biological).
