Evo in the news: Evolving conservation strategies
This news brief, from June 2007, explains how biologists are using evolutionary theory to protect the biodiversity that exists today and that may evolve tomorrow.
9-12 Article
Evo in the news: Hotspots for evolution
Why are there so many different species in the tropics? This news brief, from June 2006, suggests why: warmer weather may be linked to a quicker pace for evolution.
9-12 Article
Evo in the news: Where species come from
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.

How to survive a mass extinction: The work of David Jablonski
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.

Interview: Anthony Barnosky on climate change and mammal evolution
UC Berkeley Professor Anthony Barnosky gives the inside scoop on how climate change has affected past speciation of mammals and how it may affect biodiversity in the future.

9-12 Interview with Scientist
Modeling Modes of Evolution- PuncEq & Gradualism
Students learn the differences between “gradualism” and “punctuated equilibrium” by manipulating two sets of simulated fossils (Caminalcules).
9-12 Classroom activity
Parsimonious explanations for punctuated patterns
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.

Using trees to understand plants: The work of Chelsea Specht
This research profile follows scientist Chelsea Specht as she pieces together the evolutionary history of tropical plants and their pollinators--and in the process, tries to figure out how to conserve endangered species.
9-12 Article
Visualizing life on Earth: Data interpretation in evolution
This web-based module leads students through an exploration of the patterns in the diversity of life across planet Earth. Students are scaffolded as they practice data interpretation and scientific reasoning skills.
