Explaining Evolution - Darwin Proposes Descent with Modification
Who? - Darwin, born 1809, scientist
What? - collected evidence to support theory of evolution
When? - sailed on HMS Beagle 1831
Where? - S. America, Galapagos Islands
How? - sailed on HMS Beagle, observations
Why? - Noticed similarities between organisms in Europe and
S. America. Wanted to know why!
Proposed that all organisms on earth are related through descent from some unknown ancestor.

Voyage of the HMS Beagle
• Stopped in Galapagos Islands

Darwin’s finches
• Differences in beaks
– different foods
• Darwin’s conclusions
– when original South

HW: Complete Natural Selection Lab. Packet.

Process and Procedure #1-2, pg. 59
Scenario #1: Penicillin and other antibiotics were not available in 1925. (Penicillin was discovered in the late 1920s and was available in 1925.) So, doctors had no way to treat a staph infection at that time.
Scenario #2: In the 1945 scenario, the patient has the same infection, but is treated with penicillin, which kills the bacteria.
Scenario #3: By 1965, penicillin had been used so often that some resistant bacteria strains had evolved. Although the classic treatment is administered, the patient does not survive because the bacteria are different and do not respond to penicillin.

Study the graph in Figure 2.10 on page 60:
• What information is listed on the axes?
• What is the testable question?
• Describe the data shown in the graph.
• What conclusions can be drawn from the graph?

Process and Procedure #1-2, pg. 59
1. Read the background on antibiotics and study the graph in
Figure 2.10. Describe why the outcomes for the 3 scenarios are different?
2. For each outcome, write 1 paragraph that explains why that outcome is possible at that time of history.

• What conclusions can be drawn from the graph?

In a short essay (about a paragraph), explain how the example of bacterial infection listed in scenario 1, 2, and 3 illustrates evolution in action in modern times. Use specific examples and evidence to support your claim!
Include the following terms: evolution, variation, mutation, adaptation, and natural selection.
What kind of evolutionary change do we see in the bacteria population?
What is the factor in the bacteria’s environment that exerts environmental pressure for natural selection?
What is the role of variation in creating resistant strains of bacteria?
What is the role of new generations in creating resistant strains of bacteria?
