Evo in the news: Where species come from
Grade Level(s):
- 9-12
- 13-16
- General
Source:
- UC Museum of Paleontology
Resource type:
- Evo in the News article
Time: 15 minutes
Overview
Lush tropical ecosystems house many times more species than temperate or Arctic regions. This news brief from November 2006 discusses the evolutionary explanation for this diversity trend and reveals why threats to tropical ecosystems may threaten diversity on a global scale.
Exploring KT extinction patterns
Grade Level(s):
- 13-16
- Advanced
Source:
- UC Museum of Paleontology
Resource type:
- Lab activity
Time: 2-3 hours
Overview
Students will be introduced to a data set about mollusk genera that survived and did not survive the KT extinction event. They will formulate hypotheses regarding extinction patterns and mechanisms and analyze the data for evidence relevant to those hypotheses.
Extinction with Melissa Kemp and Liz Hadly
Grade Level(s):
- 9-12
- 13-16
Source:
- UC Museum of Paleontology
Resource type:
- Classroom activity
Time: 1.5 hours
Overview
In this article (and the linked assignments and student readings), students examine and interpret data that Melissa and Liz used to study the extinction bias in Caribbean lizards. Use the tabs at the bottom of the feature to find related videos, assignments, and lessons to build this example into a lesson sequence on extinction.
How to survive a mass extinction: The work of David Jablonski
Grade Level(s):
- 9-12
- 13-16
- General
Source:
- UC Museum of Paleontology
Resource type:
- Research profile
Time: 40 minutes
Overview
Through detailed analysis of patterns in the fossil record, scientist David Jablonski reconstructs the rules that helped dictate who lived and died in past mass extinctions. This research profile describes his surprising discoveries and their disturbing implications for the biodiversity crisis today.
Mass extinction
Grade Level(s):
- 9-12
- 13-16
- Advanced
- General
Source:
- UC Museum of Paleontology
Resource type:
- Tutorial
Time: 30 minutes
Overview
Usually, extinction operates at a fairly constant rate, culling some species while speciation generates new ones. However, at a few points in life's history the humdrum of regular extinction has been interrupted by mass extinctions. Learn more about these biodiversity crises.

- Article
Time: 1.5 hours
Overview
This excerpted chapter from Carl Zimmer's book, The Tangled Bank, describes the evolutionary processes responsible for large scale patterns in the diversity of life through time. Reprinted with the permission of Roberts and Company Publishers, Inc.
