Natural selection may favor individuals with one extreme value for a trait, shifting the average value of that trait in one direction over the course of many generations.
Evo in the News: Acidic oceans prompt evolution
Grade Level(s):
- 13-16
- Advanced
Source:
- UC Museum of Paleontology
Resource type:
- Evo in the News article
Time: 30 minutes
Overview
This news brief, from October 2012, describes new research into the evolutionary response that ocean acidification may prompt in some plankton species.
Evo in the news: Gender-biased bacteria throw off an evolutionary balance
Grade Level(s):
- 13-16
- Advanced
Source:
- UC Museum of Paleontology
Resource type:
- Evo in the News article
Time: 10 minutes
Overview
The percentage of southwestern whiteflies infected with Rickettsia bacteria has skyrocketed; but this is not a boon for local farmers, as the bacterium actively helps the pest spread. This news brief examines how evolutionary theory accounts for this and how we might turn it in our favor.
Inducing Evolution in Bean Beetles
Grade Level(s):
- 13-16
Source:
- Morehouse College and Emory University
Resource type:
- Lab activity
Time: Multi-week
Overview
In this lab, students design and conduct experiments to evaluate whether evolution by natural selection (or alternatively, genetic drift) may be induced in laboratory populations.
Problem-based discussion: Natural selection in Darwin’s finches
Grade Level(s):
- 13-16

- UC Museum of Paleontology
Resource type:
Time: 5-20 minutes
Overview
This set of two PowerPoint slides featuring questions for problem-based discussion (i.e., open-ended questions that engage students with each other and with course material) can be easily incorporated into lectures on natural selection.

Time: 1-2 class periods
Overview
This classroom exercise introduces the concept of evolution by natural selection in a hypothesis-driven, experimental fashion, using a deck of cards.
