Biol 103 - Sex, Death, & Evolution

Course description

Evolution is the conceptual foundation for all the life sciences. Using examples that are inherently engaging—because they involve sex and death—this course will provide an educated citizen’s overview of theoretical and empirical evolutionary biology. Designed for non-majors.

Learning goals

After taking Sex, Death, & Evolution, students will be able to:

  • Critically evaluate stories on evolution in the popular press;
  • Recognize and correct misconceptions about evolution;
  • Ask good questions about evolution, suggest reasonable answers, design simple studies, and perform basic graphical analyses of data;
  • Make informed personal and political decisions on issues related to evolution.

Topics for each session

The first two-thirds of the course covers basic concepts via compelling examples; the last third covers interesting questions that will each draw on multiple concepts from earlier in the quarter.
