Teaching the Biology of Gender, Sex, and Sexuality Leads to a Marked Increase in Acceptance of the Theory of Evolution by Natural Selection

Abstract

Biology education in the U.S. is under threat due to resistance to the principles of modern evolutionary theory. Although religious and cultural prejudices heavily influence this resistance, poor understanding of evolutionary theory itself is at least partly responsible. Thus, coherent and aggressive strategies are needed in order to rectify this poor understanding and properly educate the next generation of the electorate and its policy makers. Herein, we examine acceptance of evolutionary concepts among students in a majors-level introductory biology course and those in a gender studies course on sex, gender, and sexuality. Through pre-and post-course surveys, we measured the change in their acceptance. Surprisingly, students in the gender studies course consistently displayed greater improvement in their acceptance of evolutionary theory than the biology students, despite only tangential coverage of these topics in the gender studies course and substantial coverage of them in the biology course. These results provide evidence that one strategy for advancing the proper education of biology and natural history is throughteaching of the biological basis of reproduction and sexuality, topicsthat exhibit a high level of student interest and uniquely convey the effects and consequence of evolutionary forces such as natural and sexual selection, adaptation, mutation, and genetic drift.
