1. Evolutionary Biology
Visible Thinking

2. Step 1: Introduce Anchor Phenomenon
Explanation Game
I notice that…
How/why did it happen that way?

3. Think Pair Share Why are they different?
Siberian Husky
Greyhound
Why are they different?
How did they become different?

4. Compare And Contrast How are they the same? How are they different?
Cheetah
Jaguar
How are they the same?
How are they different?

5. Think-Pair-Share Why are they different?
How did they become different?
Above: Cheetah on the African plain (start video at 0:28)
At right: Jaguar in the South American jungle (start video at 1:20)

6. Step 2: Revisit Anchor Phenomenon
Revisit the work you completed at the beginning of the unit (see step 1 above). The process of humans selectively breeding dogs is called artificial selection. Through the various activities we’ve completed together in class, you have also learned about natural selection.
Complete the compare/contrast chart to show the similarities and differences between artificial selection and natural selection.

7. Step 3: Evidence for Evolution
Your Task: Construct a claim-evidence-reasoning explanation to communicate the details about ONE of the lines of evidence to support common descent and evolutionary theory.
Claim: _______________________ demonstrate(s) that different species have descended from a common ancestor.
Evidence: (from the activity or the negotiated notes)
Reasoning:
