This set of two PowerPoint slides featuring personal response questions (i.e., multiple choice questions that can be used with "clicker" technology) can be incorporated into lectures on the mechanisms of evolution in order to actively engage students in thinking about evolution.

Teaching tips:
With increased experience, the instructor will be able to develop new personal response questions, optimizing them for particular applications and topics. To learn more about how personal response questions and other types of active learning activities can be easily incorporated into lecture (and for more downloadable slides!), visit our guide to active learning in the undergraduate classroom.

Correspondence to the Next Generation Science Standards is indicated in parentheses after each relevant concept. See our conceptual framework for details.

  • Smaller populations are more strongly affected by genetic drift than are larger populations.

  • Genetic drift can cause loss of genetic variation in a population.

  • Founder effects occur when a population is founded from a small number of individuals.

  • Founder effects can affect the genetic makeup of a newly started population (and reduce its genetic variation) through sampling error.
