2018 revision

The Student Handout for Evolution by Natural Selection has been substantially revised to improve clarity and to incorporate more challenges for students to think critically and creatively. The section on peppered moths has been expanded to include student analysis of trends in allele frequencies. In addition, we now offer a small group version of the simulation of natural selection that engages students more actively in understanding the simulation and natural selection. Revisions of the Teacher Preparation Notes clarify the instructions and provide additional background information.
