Why Is Evolution Important Now? Antibiotic Resistance

Students participated in an adapted activity found at:
then did the following assignment:

If a bacterium can divide and produce 2 bacteria every 20 minutes, how soon will the two initially surviving resistant germs reach a total of one million organisms? 10 million? 100 million? One billion bacteria? Populations of this size, if pathogenic, are more than adequate to cause great harm.

Students then completed a note-taking study guide that is a companion to the following website:
and other websites listed on the study guide.

Students watched Debi's Story about antibiotic resistant tuberculosis, as part of a lesson about why understanding evolution is important now. They also watched a video about diseases.

Students watched a video titled: Why Is Evolution Important Now? This video is available to watch online at:

Information and visual diagrams that explain how antibiotic resistance develops:

Knowledge of evolution assists in choosing the appropriate drugs for treating bacterial infections:

Exposure to antibiotics can not only cause resistance to the antibiotics, it can also cause the mutant bacteria to reproduce faster!

For more reasons to understand evolution, the following posts also address the question: Why is Evolution Important Now?
