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.
