Time: 40 minutes
Overview
Wondering how global warming will affect our planet? Scientist Jennifer McElwain studies the fossil record in order to learn more about how global warming has affected life on Earth in the past and how it might affect life on Earth in the future.
Discovering mass extinctions in the fossil record
Grade Level(s):
- 13-16
Source:
- UC Museum of Paleontology
Resource type:
- Online activity or lab
Time: 2 hours
Overview
This activity (suitable for distance learning) is designed to introduce students to the nature and process of science through the discovery of mass extinctions in the fossil record. Students will explore the fossil record of brachiopods and bivalves using the Paleobiological Database, identify patterns in their data, and generate and evaluate hypotheses. They will also document this process using the Understanding Science flowchart. Clicking the link above will download the Word file for this lesson.

Grade Level(s):
- 13-16
- Advanced
Source:
- UC Museum of Paleontology
Resource type:

Time: 30 minutes
Overview
This news brief, from May 2012, describes new research on the end-Ordovician mass extinction and the lessons we might glean about extinctions going on around us today.
Evo in the news: The evidence lines up in early mammal evolution
Grade Level(s):

- General
Source:
- UC Museum of Paleontology
Resource type:
- Evo in the News article
Time: 15 minutes
Overview
This news brief, from September 2011, describes the discovery of a new mammal species that highlights just how long mammals have been around. Back in the Jurassic, dinosaurs may have dominated terrestrial ecosystems, but they were not alone. Scurrying around their feet and clinging to the trees above them were the fuzzy ancestors of their successors.
Evo in the News: What comes after mass extinctions?
Grade Level(s):
- 13-16

Time: 30 minutes
Overview
This news brief, from September 2012, describes the aftermath of mass extinctions--what happens to surviving species in the wake of a massive extinction event.
Evo in the news: Where species come from
Grade Level(s):

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

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.

How to survive a mass extinction: The work of David Jablonski
Grade Level(s):
- 9-12

- 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.
Parsimonious explanations for punctuated patterns
Grade Level(s):

- General
Source:
- Evolution: Education and Outreach
Resource type:
- Article
Time: 40 minutes
Overview
Punctuated equilibrium is sometimes erroneously cited as evidence that evolutionary biology still hasn't figured out how evolution works. In fact nothing could be further from the truth. Punctuated equilibrium builds on (not tears down!) established evolutionary theory. Find out how the process works.
