Evolution and E. coli: Natural selection in a constant environment
Grade Level(s):
- 9-12
Source:
- BiteScis
Resource type:
- Classroom activity
Time: Two to three 50-minute class periods
Overview
In this reading-, writing-, and discussion-based activity, students explore bacterial evolution occurring in a stable environment, which counters the intuitive misconception that environmental change is a necessary component to natural selection. A landmark study provides the backdrop against which students can challenge their thinking about what it means for a population to evolve.
Evolution of human skin color

- Smithsonian National Museum of Natural History
Resource type:
- Classroom activity
Time: Seven to ten 50 minute class periods
Overview
Students examine evidence for the relationship between UV and melanin in other animals; investigate the genetic basis for constitutive skin color humans; learn to test for natural selection in mouse fur color; investigate how interactions between UV and skin color in humans can affect fitness; and explore data on migrations and gene frequency to show convergent evolution of skin color.
