This review will guide you through an adaptive, research-backed study session. As you answer questions, we will actively assess your current understanding of the material. Questions will continue to be drawn until you have demonstrated mastery of each learning objective.

Reviews are graded based on completion. You will receive full credit for achieving 100% mastery or answering all questions.

Learning objectives for this review:

  • Explain how selective pressures, such as predation, competition, and environmental factors, influence the survival and reproduction of organisms.
  • Investigate specific case studies, such as antibiotic resistance in bacteria and the peppered moth, to illustrate natural selection.
  • Explain how natural selection can lead to adaptation, speciation, and changes in allele frequencies in populations.
