 | What did T. Rex Taste Like?
In this web-based module students are introduced to cladistics, which organizes living things by common ancestry and evolutionary relationships.

 | Understanding Macroevolution Through Evograms
Evograms convey information about how a group of organisms and their particular features evolved. This article explains how to read evograms and delves into the evolutionary history of whales, tetrapods, mammals, birds, and humans.

 | A Strange Fish Indeed: The “Discovery” of a Living Fossil
Through a series of fictionalized diary entries, this case recounts the 1939 discovery by Marjorie Courtenay-Latimer (and identification by J.L.B. Smith) of a living coelacanth, a fish believed to have been extinct for 70 million years.

 | Anolis Lizards
Students "take a trip" to the Greater Antilles to figure out how the Anolis lizards on the islands might have evolved.

 | 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.

 | Classification and Evolution
Students construct an evolutionary tree of imaginary animals (Caminalcules) to illustrate how modern classification schemes attempt to reflect evolutionary history.

 | It takes teamwork: How endosymbiosis changed life on Earth
You might be surprised to learn that descendents of an ancient bacterium are living in every cell of your body! Find out how endosymbiosis factored into the evolution of your own cells and learn about a modern example of this process.

 | Evo in the news: The evidence lines up in early mammal evolution
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.
