Synopsis
- In this activity, students learn about natural selection in populations by analyzing and interpreting two graphs showing how anole lizards adapt to extremely cold temperatures.
- The graphs are from a study in which scientists investigated how winter storms in Texas affected local populations of anoles.

Teaching Materials
Positives
- The educator materials document contains labeled illustrations, background information, interpretation of the illustrations, and discussion questions.
- Students learn how to analyze data from a scientific illustration and understand how natural selection is impacted by climate change.
Additional Prerequisites
- The resource includes an educator guide and student handout in PDF format.
- The image of Texas and the two graphs are available to download as JPGs.
Differentiation
- For students needing additional guidance, the teacher could lead the discussion and help students develop observations and interpretations.
- Advanced students may be asked to write a paragraph on the relationship between extreme climate events, natural selection, and animal adaptation based on this resource.
- The teacher could ask students to complete a project in which they study another species affected by extreme climate events.
- Other resources related to the topic include the video Ecosystem Dynamics, Functioning and Resilience and the article 5 Plants and Animals Utterly Confused by Climate change.
The resource describes changes in evolution as a result of the cascading climate change impact. The graphs shows the distribution of lizards and the changes within a critical thermal minimum. There is no contradiction in the model; thus, this resource is recommended for teaching.
